3.5.2 Add more tests to ff-group-tests
The audit recommends checking failure cases for from_bytes,
from_bytes_unechecked, and from_repr. This isn't feasible.

from_bytes is allowed to have non-canonical values. [0xff; 32] may accordingly
be a valid point for non-SEC1-encoded curves.

from_bytes_unchecked doesn't have a defined failure mode, and by name,
unchecked, shouldn't necessarily fail. The audit acknowledges the tests should
test for whatever result is 'appropriate', yet any result which isn't a failure
on a valid element is appropriate.

from_repr must be canonical, yet for a binary field of 2^n where n % 8 == 0, a
[0xff; n / 8] repr would be valid.

* updated test_send

* added bitcoin ci & updated test-dependencies yml

* fixed bitcoin ci

* updated bitcoin ci yml

* Remove mining from the bitcoin/monero docker files

The tests should control block production in order to test various
circumstances. The automatic mining disrupts assumptions made in testing. Since
we're now using the Bitcoin docker container for testing...

* Multiple fixes to the Bitcoin processor

Doesn't unwrap on RPC errors. Returns the expected connection error.

Fee calculation has a random - 1. This has been removed.

Supports the change address being an Option, as it is. This should not have
been blindly unwrapped.

* Remove unnecessary RPC code

* Further RPC simplifications

* Simplify Bitcoin action

It should not be mining.

* cargo fmt

* Finish RPC simplifications

* Run bitcoind as a daemon

* Remove the requirement on txindex

Saves tens of GB.

Also has attempt_send no longer return a list of outputs. That's incompatible
with this and only relevant to old scheduling designs.

* Remove number from Bitcoin SignableTransaction

Monero requires the current block number for decoy selection. Bitcoin doesn't
have a use.

* Ban coinbase transactions

These are burdened by maturity, so it's critically flawed to support them.

This causes the test_send function to fail as its working was premised on
a coinbase output. While it does make an actual output, it had insufficient
funds for the test's expectations due to regtest halving every 150 blocks.

In order to workaround this, the test will invalidate any existing chain,
offering a fresh start.

Also removes test_get_spendables and simplifies test_send.

* Various simplifications

Modifies SpendableOutput further to not require RPC calls at time of sign.

Removes the need to have get_transaction in the RPC.

* Clean prepare_send

* Update the Bitcoin TransactionMachine to output a Transaction

* Bitcoin TransactionMachine simplifications

* Update XOnly key handling

Tokens pallet (#243)
* Use Monero-compatible additional TX keys

This still sends a fingerprinting flare up if you send to a subaddress which
needs to be fixed. Despite that, Monero no should no longer fail to scan TXs
from monero-serai regarding additional keys.

Previously it failed becuase we supplied one key as THE key, and n-1 as
additional. Monero expects n for additional.

This does correctly select when to use THE key versus when to use the additional
key when sending. That removes the ability for recipients to fingerprint
monero-serai by receiving to a standard address yet needing to use an additional
key.

* Add tokens_primitives

Moves OutInstruction from in-instructions.

Turns Destination into OutInstruction.

* Correct in-instructions DispatchClass

* Add initial tokens pallet

* Don't allow pallet addresses to equal identity

* Add support for InInstruction::transfer

Requires a cargo update due to modifications made to serai-dex/substrate.

Successfully mints a token to a SeraiAddress.

* Bind InInstructions to an amount

* Add a call filter to the runtime

Prevents worrying about calls to the assets pallet/generally tightens things
up.

* Restore Destination

It was meged into OutInstruction, yet it didn't make sense for OutInstruction
to contain a SeraiAddress.

Also deletes the excessively dated Scenarios doc.

* Split PublicKey/SeraiAddress

Lets us define a custom Display/ToString for SeraiAddress.

Also resolves an oddity where PublicKey would be encoded as String, not
[u8; 32].

* Test burning tokens/retrieving OutInstructions

Modularizes processor_coinUpdates into a shared testing utility.

* Misc lint

* Don't use PolkadotExtrinsicParams

* Add in-instructions to the node

* Add the Serai runtime API to the processor

* Move processor tests around

* Build a subxt Client around Serai

* Successfully get Batch events from Serai

Renamed processor/substrate to processor/serai.

* Much more robust InInstruction pallet

* Implement the workaround from https://github.com/paritytech/subxt/issues/602

* Initial prototype of processor generated InInstructions

* Correct PendingCoins data flow for InInstructions

* Minor lint to in-instructions

* Remove the global Serai connection for a partial re-impl

* Make an unwrap an if let Some, remove old comments

* Lint the processor toml

* Rebase and update

* Move substrate/in-instructions to substrate/in-instructions/pallet

* Start an in-instructions primitives lib

* Properly update processor to subxt 0.24

Also corrects failures from the rebase.

* in-instructions cargo update

* Implement IsFatalError

* is_inherent -> true

* Rename in-instructions crates and misc cleanup

* Update documentation

* cargo update

* Misc update fixes

* Replace height with block_number

* Update processor src to latest subxt

* Correct pipeline for InInstructions testing

* Remove runtime::AccountId for serai_primitives::NativeAddress

* Rewrite the in-instructions pallet

Complete with respect to the currently written docs.

Drops the custom serializer for just using SCALE.

Makes slight tweaks as relevant.

* Move instructions' InherentDataProvider to a client crate

* Correct doc gen

* Add serde to in-instructions-primitives

* Add in-instructions-primitives to pallet

* Heights -> BlockNumbers

* Correct processor sleeps

* Remove metadata at compile time, add test framework for Serai nodes

* Remove manual RPC client

* Simplify update test

* Improve re-exporting behavior of serai-runtime

It now re-exports all pallets underneath it.

* Add a function to get storage values to the Serai RPC

* Update substrate/ to latest substrate

* Create a dedicated crate for the Serai RPC

* Remove unused dependencies in substrate/

* Remove unused dependencies in coins/

Out of scope for this branch, just minor and path of least resistance.

* Use substrate/serai/client for the Serai RPC lib

It's a bit out of place, since these client folders are intended for the node to
access pallets and so on. This is for end-users to access Serai as a whole.

In that sense, it made more sense as a top level folder, yet that also felt
out of place.

* Move InInstructions test to serai-client for now

* Final cleanup

* Update deny.toml

* Cargo.lock update from merging develop

* Update nightly

Attempt to work around the current CI failure, which is a Rust ICE.

We previously didn't upgrade due to clippy 10134, yet that's been reverted.

* clippy

* clippy

* fmt

* NativeAddress -> SeraiAddress

* Sec fix on non-provided updates and doc fixes

* Add Serai as a Coin

Necessary in order to swap to Serai.

* Add a BlockHash type, used for batch IDs

* Remove origin from InInstruction

Makes InInstructionTarget. Adds RefundableInInstruction with origin.

* Document storage items in in-instructions

* Rename serai/client/tests/serai.rs to updates.rs

It only tested publishing updates and their successful acceptance.

Initial validator sets pallet (#187)
* Initial work on a Validator Sets pallet

* Update Validator Set docs per current discussions

* Update validator-sets primitives and storage handling

* Add validator set pallets to deny.toml

* Remove Curve from primitives

Since we aren't reusing keys across coins, there's no reason for it to be
on-chain (as previously planned).

* Update documentation on Validator Sets

* Use Twox64Concat instead of Identity

Ensures an even distribution of keys. While xxhash is breakable, these keys
aren't manipulatable by users.

* Add math ops on Amount and define a coin as 1e8

* Add validator-sets to the runtime and remove contracts

Also removes the randomness pallet which was only required by the contracts
runtime.

Does not remove the contracts folder yet so they can still be referred to while
validator-sets is under development. Does remove them from Cargo.toml.

* Add vote function to validator-sets

* Remove contracts folder

* Create an event for the Validator Sets pallet

* Remove old contracts crates from deny.toml

* Remove line from staking branch

* Remove staking from runtime

* Correct VS Config in runtime

* cargo update

* Resolve a few PR comments on terminology

* Create a serai-primitives crate

Move types such as Amount/Coin out of validator-sets. Will be expanded in the
future.

* Fixes for last commit

* Don't reserve set 0

* Further fixes

* Add files meant for last commit

* Remove Staking transfer

Support caching preprocesses in FROST (#190)
* Remove the explicit included participants from FROST

Now, whoever submits preprocesses becomes the signing set. Better separates
preprocess from sign, at the cost of slightly more annoying integrations
(Monero needs to now independently lagrange/offset its key images).

* Support caching preprocesses

Closes https://github.com/serai-dex/serai/issues/40.

I *could* have added a serialization trait to Algorithm and written a ton of
data to disk, while requiring Algorithm implementors also accept such work.
Instead, I moved preprocess to a seeded RNG (Chacha20) which should be as
secure as the regular RNG. Rebuilding from cache simply loads the previously
used Chacha seed, making the Algorithm oblivious to the fact it's being
rebuilt from a cache. This removes any requirements for it to be modified
while guaranteeing equivalency.

This builds on the last commit which delayed determining the signing set till
post-preprocess acquisition. Unfortunately, that commit did force preprocess
from ThresholdView to ThresholdKeys which had visible effects on Monero.

Serai will actually need delayed set determination for #163, and overall,
it remains better, hence it's inclusion.

* Document FROST preprocess caching

* Update ethereum to new FROST

* Fix bug in Monero offset calculation and update processor

Clean and document the DKG library's encryption
Encryption used to be inlined into FROST. When writing the documentation, I
realized it was decently hard to review. It also was antagonistic to other
hosted DKG algorithms by not allowing code re-use.

Encryption is now a standalone module, providing clear boundaries and
reusability.

Additionally, the DKG protocol itself used to use the ciphersuite's specified
hash function (with an HKDF to prevent length extension attacks). Now,
RecommendedTranscript is used to achieve much more robust transcripting and
remove the HKDF dependency. This does add Blake2 into all consumers yet is
preferred for its security properties and ease of review.

Initial Tendermint implementation (#145)
* Machine without timeouts

* Time code

* Move substrate/consensus/tendermint to substrate/tendermint

* Delete the old paper doc

* Refactor out external parts to generics

Also creates a dedicated file for the message log.

* Refactor <V, B> to type V, type B

* Successfully compiling

* Calculate timeouts

* Fix test

* Finish timeouts

* Misc cleanup

* Define a signature scheme trait

* Implement serialization via parity's scale codec

Ideally, this would be generic. Unfortunately, the generic API serde 
doesn't natively support borsh, nor SCALE, and while there is a serde 
SCALE crate, it's old. While it may be complete, it's not worth working 
with.

While we could still grab bincode, and a variety of other formats, it 
wasn't worth it to go custom and for Serai, we'll be using SCALE almost 
everywhere anyways.

* Implement usage of the signature scheme

* Make the infinite test non-infinite

* Provide a dedicated signature in Precommit of just the block hash

Greatly simplifies verifying when syncing.

* Dedicated Commit object

Restores sig aggregation API.

* Tidy README

* Document tendermint

* Sign the ID directly instead of its SCALE encoding

For a hash, which is fixed-size, these should be the same yet this helps 
move past the dependency on SCALE. It also, for any type where the two 
values are different, smooths integration.

* Litany of bug fixes

Also attempts to make the code more readable while updating/correcting 
documentation.

* Remove async recursion

Greatly increases safety as well by ensuring only one message is 
processed at once.

* Correct timing issues

1) Commit didn't include the round, leaving the clock in question.

2) Machines started with a local time, instead of a proper start time.

3) Machines immediately started the next block instead of waiting for 
the block time.

* Replace MultiSignature with sr25519::Signature

* Minor SignatureScheme API changes

* Map TM SignatureScheme to Substrate's sr25519

* Initial work on an import queue

* Properly use check_block

* Rename import to import_queue

* Implement tendermint_machine::Block for Substrate Blocks

Unfortunately, this immediately makes Tendermint machine capable of 
deployment as  crate since it uses a git reference. In the future, a 
Cargo.toml patch section for serai/substrate should be investigated. 
This is being done regardless as it's the quickest way forward and this 
is for Serai.

* Dummy Weights

* Move documentation to the top of the file

* Move logic into TendermintImport itself

Multiple traits exist to verify/handle blocks. I'm unsure exactly when 
each will be called in the pipeline, so the easiest solution is to have 
every step run every check.

That would be extremely computationally expensive if we ran EVERY check, 
yet we rely on Substrate for execution (and according checks), which are 
limited to just the actual import function.

Since we're calling this code from many places, it makes sense for it to 
be consolidated under TendermintImport.

* BlockImport, JustificationImport, Verifier, and import_queue function

* Update consensus/lib.rs from PoW to Tendermint

Not possible to be used as the previous consensus could. It will not
produce blocks nor does it currenly even instantiate a machine. This is
just he next step.

* Update Cargo.tomls for substrate packages

* Tendermint SelectChain

This is incompatible with Substrate's expectations, yet should be valid 
for ours

* Move the node over to the new SelectChain

* Minor tweaks

* Update SelectChain documentation

* Remove substrate/node lib.rs

This shouldn't be used as a library AFAIK. While runtime should be, and 
arguably should even be published, I have yet to see node in the same 
way. Helps tighten API boundaries.

* Remove unused macro_use

* Replace panicking todos with stubs and // TODO

Enables progress.

* Reduce chain_spec and use more accurate naming

* Implement block proposal logic

* Modularize to get_proposal

* Trigger block importing

Doesn't wait for the response yet, which it needs to.

* Get the result of block importing

* Split import_queue into a series of files

* Provide a way to create the machine

The BasicQueue returned obscures the TendermintImport struct. 
Accordingly, a Future scoped with access is returned upwards, which when 
awaited will create the machine. This makes creating the machine 
optional while maintaining scope boundaries.

Is sufficient to create a 1-node net which produces and finalizes 
blocks.

* Don't import justifications multiple times

Also don't broadcast blocks which were solely proposed.

* Correct justication import pipeline

Removes JustificationImport as it should never be used.

* Announce blocks

By claiming File, they're not sent ovber the P2P network before they 
have a justification, as desired. Unfortunately, they never were. This 
works around that.

* Add an assert to verify proposed children aren't best

* Consolidate C and I generics into a TendermintClient trait alias

* Expand sanity checks

Substrate doesn't expect nor officially support children with less work 
than their parents. It's a trick used here. Accordingly, ensure the 
trick's validity.

* When resetting, use the end time of the round which was committed to

The machine reset to the end time of the current round. For a delayed 
network connection, a machine may move ahead in rounds and only later 
realize a prior round succeeded. Despite acknowledging that round's 
success, it would maintain its delay when moving to the next block, 
bricking it.

Done by tracking the end time for each round as they occur.

* Move Commit from including the round to including the round's end_time

The round was usable to build the current clock in an accumulated 
fashion, relative to the previous round. The end time is the absolute 
metric of it, which can be used to calculate the round number (with all 
previous end times).

Substrate now builds off the best block, not genesis, using the end time 
included in the justification to start its machine in a synchronized 
state.

Knowing the end time of a round, or the round in which block was 
committed to, is necessary for nodes to sync up with Tendermint. 
Encoding it in the commit ensures it's long lasting and makes it readily 
available, without the load of an entire transaction.

* Add a TODO on Tendermint

* Misc bug fixes

* More misc bug fixes

* Clean up lock acquisition

* Merge weights and signing scheme into validators, documenting needed changes

* Add pallet sessions to runtime, create pallet-tendermint

* Update node to use pallet sessions

* Update support URL

* Partial work on correcting pallet calls

* Redo Tendermint folder structure

* TendermintApi, compilation fixes

* Fix the stub round robin

At some point, the modulus was removed causing it to exceed the 
validators list and stop proposing.

* Use the validators list from the session pallet

* Basic Gossip Validator

* Correct Substrate Tendermint start block

The Tendermint machine uses the passed in number as the block's being 
worked on number. Substrate passed in the already finalized block's 
number.

Also updates misc comments.

* Clean generics in Tendermint with a monolith with associated types

* Remove the Future triggering the machine for an async fn

Enables passing data in, such as the network.

* Move TendermintMachine from start_num, time to last_num, time

Provides an explicitly clear API clearer to program around.

Also adds additional time code to handle an edge case.

* Connect the Tendermint machine to a GossipEngine

* Connect broadcast

* Remove machine from TendermintImport

It's not used there at all.

* Merge Verifier into block_import.rs

These two files were largely the same, just hooking into sync structs 
with almost identical imports. As this project shapes up, removing dead 
weight is appreciated.

* Create a dedicated file for being a Tendermint authority

* Deleted comment code related to PoW

* Move serai_runtime specific code from tendermint/client to node

Renames serai-consensus to sc_tendermint

* Consolidate file structure in sc_tendermint

* Replace best_* with finalized_*

We test their equivalency yet still better to use finalized_* in 
general.

* Consolidate references to sr25519 in sc_tendermint

* Add documentation to public structs/functions in sc_tendermint

* Add another missing comment

* Make sign asynchronous

Some relation to https://github.com/serai-dex/serai/issues/95.

* Move sc_tendermint to async sign

* Implement proper checking of inherents

* Take in a Keystore and validator ID

* Remove unnecessary PhantomDatas

* Update node to latest sc_tendermint

* Configure node for a multi-node testnet

* Fix handling of the GossipEngine

* Use a rounded genesis to obtain sufficient synchrony within the Docker env

* Correct Serai d-f names in Docker

* Remove an attempt at caching I don't believe would ever hit

* Add an already in chain check to block import

While the inner should do this for us, we call verify_order on our end 
*before* inner to ensure sequential import. Accordingly, we need to 
provide our own check.

Removes errors of "non-sequential import" when trying to re-import an 
existing block.

* Update the consensus documentation

It was incredibly out of date.

* Add a _ to the validator arg in slash

* Make the dev profile a local testnet profile

Restores a dev profile which only has one validator, locally running.

* Reduce Arcs in TendermintMachine, split Signer from SignatureScheme

* Update sc_tendermint per previous commit

* Restore cache

* Remove error case which shouldn't be an error

* Stop returning errors on already existing blocks entirely

* Correct Dave, Eve, and Ferdie to not run as validators

* Rename dev to devnet

--dev still works thanks to the |. Acheieves a personal preference of 
mine with some historical meaning.

* Add message expiry to the Tendermint gossip

* Localize the LibP2P protocol to the blockchain

Follows convention by doing so. Theoretically enables running multiple 
blockchains over a single LibP2P connection.

* Add a version to sp-runtime in tendermint-machine

* Add missing trait

* Bump Substrate dependency

Fixes #147.

* Implement Schnorr half-aggregation from https://eprint.iacr.org/2021/350.pdf

Relevant to https://github.com/serai-dex/serai/issues/99.

* cargo update (tendermint)

* Move from polling loops to a pure IO model for sc_tendermint's gossip

* Correct protocol name handling

* Use futures mpsc instead of tokio

* Timeout futures

* Move from a yielding loop to select in tendermint-machine

* Update Substrate to the new TendermintHandle

* Use futures pin instead of tokio

* Only recheck blocks with non-fatal inherent transaction errors

* Update to the latest substrate

* Separate the block processing time from the latency

* Add notes to the runtime

* Don't spam slash

Also adds a slash condition of failing to propose.

* Support running TendermintMachine when not a validator

This supports validators who leave the current set, without crashing 
their nodes, along with nodes trying to become validators (who will now 
seamlessly transition in).

* Properly define and pass around the block size

* Correct the Duration timing

The proposer will build it, send it, then process it (on the first 
round). Accordingly, it's / 3, not / 2, as / 2 only accounted for the 
latter events.

* Correct time-adjustment code on round skip

* Have the machine respond to advances made by an external sync loop

* Clean up time code in tendermint-machine

* BlockData and RoundData structs

* Rename Round to RoundNumber

* Move BlockData to a new file

* Move Round to an Option due to the pseudo-uninitialized state we create

Before the addition of RoundData, we always created the round, and on 
.round(0), simply created it again. With RoundData, and the changes to 
the time code, we used round 0, time 0, the latter being incorrect yet 
not an issue due to lack of misuse.

Now, if we do misuse it, it'll panic.

* Clear the Queue instead of draining and filtering

There shouldn't ever be a message which passes the filter under the 
current design.

* BlockData::new

* Move more code into block.rs

Introduces type-aliases to obtain Data/Message/SignedMessage solely from 
a Network object.

Fixes a bug regarding stepping when you're not an active validator.

* Have verify_precommit_signature return if it verified the signature

Also fixes a bug where invalid precommit signatures were left standing 
and therefore contributing to commits.

* Remove the precommit signature hash

It cached signatures per-block. Precommit signatures are bound to each 
round. This would lead to forming invalid commits when a commit should 
be formed. Under debug, the machine would catch that and panic. On 
release, it'd have everyone who wasn't a validator fail to continue 
syncing.

* Slight doc changes

Also flattens the message handling function by replacing an if 
containing all following code in the function with an early return for 
the else case.

* Always produce notifications for finalized blocks via origin overrides

* Correct weird formatting

* Update to the latest tendermint-machine

* Manually step the Tendermint machine when we synced a block over the network

* Ignore finality notifications for old blocks

* Remove a TODO resolved in 8c51bc011d

* Add a TODO comment to slash

Enables searching for the case-sensitive phrase and finding it.

* cargo fmt

* Use a tmp DB for Serai in Docker

* Remove panic on slash

As we move towards protonet, this can happen (if a node goes offline), 
yet it happening brings down the entire net right now.

* Add log::error on slash

* created shared volume between containers

* Complete the sh scripts

* Pass in the genesis time to Substrate

* Correct block announcements

They were announced, yet not marked best.

* Correct pupulate_end_time

It was used as inclusive yet didn't work inclusively.

* Correct gossip channel jumping when a block is synced via Substrate

* Use a looser check in import_future

This triggered so it needs to be accordingly relaxed.

* Correct race conditions between add_block and step

Also corrects a <= to <.

* Update cargo deny

* rename genesis-service to genesis

* Update Cargo.lock

* Correct runtime Cargo.toml whitespace

* Correct typo

* Document recheck

* Misc lints

* Fix prev commit

* Resolve low-hanging review comments

* Mark genesis/entry-dev.sh as executable

* Prevent a commit from including the same signature multiple times

Yanks tendermint-machine 0.1.0 accordingly.

* Update to latest nightly clippy

* Improve documentation

* Use clearer variable names

* Add log statements

* Pair more log statements

* Clean TendermintAuthority::authority as possible

Merges it into new. It has way too many arguments, yet there's no clear path at
consolidation there, unfortunately.

Additionally provides better scoping within itself.

* Fix #158

Doesn't use lock_import_and_run for reasons commented (lack of async).

* Rename guard to lock

* Have the devnet use the current time as the genesis

Possible since it's only a single node, not requiring synchronization.

* Fix gossiping

I really don't know what side effect this avoids and I can't say I care at this
point.

* Misc lints

Create a dedicated crate for the DKG (#141)
* Add dkg crate

* Remove F_len and G_len

They're generally no longer used.

* Replace hash_to_vec with a provided method around associated type H: Digest

Part of trying to minimize this trait so it can be moved elsewhere. Vec, 
which isn't std, may have been a blocker.

* Encrypt secret shares within the FROST library

Reduces requirements on callers in order to be correct.

* Update usage of Zeroize within FROST

* Inline functions in key_gen

There was no reason to have them separated as they were. sign probably 
has the same statement available, yet that isn't the focus right now.

* Add a ciphersuite package which provides hash_to_F

* Set the Ciphersuite version to something valid

* Have ed448 export Scalar/FieldElement/Point at the top level

* Move FROST over to Ciphersuite

* Correct usage of ff in ciphersuite

* Correct documentation handling

* Move Schnorr signatures to their own crate

* Remove unused feature from schnorr

* Move FROST signing to messages, not Readers/Writers/Vec<u8>

aiming to resolve complex types and make the code more legible by 
replacing its previously inlined state.

* clippy

* Add a repository field

* Move generators to OUT_DIR

Unfortunately, since cargo is complaining about .generators, we have to.

FROST Ed448 (#107)
* Theoretical ed448 impl

* Fixes

* Basic tests

* More efficient scalarmul

Precomputes a table to minimize additions required.

* Add a torsion test

* Split into a constant and variable time backend

The variable time one is still far too slow, at 53s for the tests (~5s a 
scalarmul). It should be usable as a PoC though.

* Rename unsafe Ed448

It's not only unworthy of the Serai branding and deserves more clarity
in the name.

* Add wide reduction to ed448

* Add Zeroize to Ed448

* Rename Ed448 group.rs to point.rs

* Minor lint to FROST

* Ed448 ciphersuite with 8032 test vector

* Macro out the backend fields

* Slight efficiency improvement to point decompression

* Disable the multiexp test in FROST for Ed448

* fmt + clippy ed448

* Fix an infinite loop in the constant time ed448 backend

* Add b"chal" to the 8032 context string for Ed448

Successfully tests against proposed vectors for the FROST IETF draft.

* Fix fmt and clippy

* Use a tabled pow algorithm in ed448's const backend

* Slight tweaks to variable time backend

Stop from_repr(MODULUS) from passing.

* Use extended points

Almost two orders of magnitude faster.

* Efficient ed448 doubling

* Remove the variable time backend

With the recent performance improvements, the constant time backend is 
now 4x faster than the variable time backend was. While the variable 
time backend remains much faster, and the constant time backend is still 
slow compared to other libraries, it's sufficiently performant now.

The FROST test, which runs a series of multiexps over the curve, does 
take 218.26s while Ristretto takes 1 and secp256k1 takes 4.57s.

While 50x slower than secp256k1 is horrible, it's ~1.5 orders of 
magntiude, which is close enough to the desire stated in 
https://github.com/serai-dex/serai/issues/108 to meet it.

Largely makes this library safe to use.

* Correct constants in ed448

* Rename unsafe-ed448 to minimal-ed448

Enables all FROST tests against it.

* No longer require the hazmat feature to use ed448

* Remove extraneous as_refs

Utilize zeroize (#76)
* Apply Zeroize to nonces used in Bulletproofs

Also makes bit decomposition constant time for a given amount of 
outputs.

* Fix nonce reuse for single-signer CLSAG

* Attach Zeroize to most structures in Monero, and ZOnDrop to anything with private data

* Zeroize private keys and nonces

* Merge prepare_outputs and prepare_transactions

* Ensure CLSAG is constant time

* Pass by borrow where needed, bug fixes

The past few commitments have been one in-progress chunk which I've 
broken up as best read.

* Add Zeroize to FROST structs

Still needs to zeroize internally, yet next step. Not quite as 
aggressive as Monero, partially due to the limitations of HashMaps, 
partially due to less concern about metadata, yet does still delete a 
few smaller items of metadata (group key, context string...).

* Remove Zeroize from most Monero multisig structs

These structs largely didn't have private data, just fields with private 
data, yet those fields implemented ZeroizeOnDrop making them already 
covered. While there is still traces of the transaction left in RAM, 
fully purging that was never the intent.

* Use Zeroize within dleq

bitvec doesn't offer Zeroize, so a manual zeroing has been implemented.

* Use Zeroize for random_nonce

It isn't perfect, due to the inability to zeroize the digest, and due to 
kp256 requiring a few transformations. It does the best it can though.

Does move the per-curve random_nonce to a provided one, which is allowed 
as of https://github.com/cfrg/draft-irtf-cfrg-frost/pull/231.

* Use Zeroize on FROST keygen/signing

* Zeroize constant time multiexp.

* Correct when FROST keygen zeroizes

* Move the FROST keys Arc into FrostKeys

Reduces amount of instances in memory.

* Manually implement Debug for FrostCore to not leak the secret share

* Misc bug fixes

* clippy + multiexp test bug fixes

* Correct FROST key gen share summation

It leaked our own share for ourself.

* Fix cross-group DLEq tests

Remove Monero as a dependency
Introduces missing CLSAG checks. The only difference now should be the 
additional rejection of torsioned points, which is relevant to 
https://github.com/serai-dex/serai/issues/25. Considering this is only 
currently used for FROST verification, this should be fine.

Closes https://github.com/serai-dex/serai/issues/19 by making it 
irrelevant.

Increases priority of https://github.com/serai-dex/serai/issues/68, as 
now it's used for the BP generators which are done at first-proof.

Also merges BP's stricter hash_to_point with the library's, since CLSAG 
has the same bound.

Implement Bulletproofs in Rust (#69)
* Initial attempt at Bulletproofs

I don't know why this doesn't work. The generators and hash_cache lines
up without issue. AFAICT, the inner product proof is valid as well, as
are all included formulas.

* Add yinvpow asserts

* Clean code

* Correct bad imports

* Fix the definition of TWO_N

Bulletproofs work now :D

* Tidy up a bit

* fmt + clippy

* Compile a variety of XMR dependencies with optimizations, even under dev

The Rust bulletproof implementation is 8% slower than C right now, under 
release. This is acceptable, even if suboptimal. Under debug, they take 
a quarter of a second to two seconds though, depending on the amount of 
outputs, which justifies this move.

* Remove unnecessary deref in BPs
