Validator DHT (#494)
* Route validators for any active set through sc-authority-discovery

Additionally adds an RPC route to retrieve their P2P addresses.

* Have the coordinator get peers from substrate

* Have the RPC return one address, not up to 3

Prevents the coordinator from believing it has 3 peers when it has one.

* Add missing feature to serai-client

* Correct network argument in serai-client for p2p_validators call

* Add a test in serai-client to check DHT population with a much quicker failure than the coordinator tests

* Update to latest Substrate

Removes distinguishing BABE/AuthorityDiscovery keys which causes
sc_authority_discovery to populate as desired.

* Update to a properly tagged substrate commit

* Add all dialed to peers to GossipSub

* cargo fmt

* Reduce common code in serai-coordinator-tests with amore involved new_test

* Use a recursive async function to spawn `n` DockerTests with the necessary networking configuration

* Merge UNIQUE_ID and ONE_AT_A_TIME

* Tidy up the new recursive code in tests/coordinator

* Use a Mutex in CONTEXT to let it be set multiple times

* Make complimentary edits to full-stack tests

* Augment coordinator P2p connection logs

* Drop lock acquisitions before recursing

* Better scope lock acquisitions in full-stack, preventing a deadlock

* Ensure OUTER_OPS is reset across the test boundary

* Add cargo deny allowance for dockertest fork

Coordinator Cleanup (#481)
* Move logic for evaluating if a cosign should occur to its own file

Cleans it up and makes it more robust.

* Have expected_next_batch return an error instead of retrying

While convenient to offer an error-free implementation, it potentially caused
very long lived lock acquisitions in handle_processor_message.

* Unify and clean DkgConfirmer and DkgRemoval

Does so via adding a new file for the common code, SigningProtocol.

Modifies from_cache to return the preprocess with the machine, as there's no
reason not to. Also removes an unused Result around the type.

Clarifies the security around deterministic nonces, removing them for
saved-to-disk cached preprocesses. The cached preprocesses are encrypted as the
DB is not a proper secret store.

Moves arguments always present in the protocol from function arguments into the
struct itself.

Removes the horribly ugly code in DkgRemoval, fixing multiple issues present
with it which would cause it to fail on use.

* Set SeraiBlockNumber in cosign.rs as it's used by the cosigning protocol

* Remove unnecessary Clone from lambdas in coordinator

* Remove the EventDb from Tributary scanner

We used per-Transaction DB TXNs so on error, we don't have to rescan the entire
block yet only the rest of it. We prevented scanning multiple transactions by
tracking which we already had.

This is over-engineered and not worth it.

* Implement borsh for HasEvents, removing the manual encoding

* Merge DkgConfirmer and DkgRemoval into signing_protocol.rs

Fixes a bug in DkgConfirmer which would cause it to improperly handle indexes
if any validator had multiple key shares.

* Strictly type DataSpecification's Label

* Correct threshold_i_map_to_keys_and_musig_i_map

It didn't include the participant's own index and accordingly was offset.

* Create TributaryBlockHandler

This struct contains all variables prior passed to handle_block and stops them
from being passed around again and again.

This also ensures fatal_slash is only called while handling a block, as needed
as it expects to operate under perfect consensus.

* Inline accumulate, store confirmation nonces with shares

Inlining accumulate makes sense due to the amount of data accumulate needed to
be passed.

Storing confirmation nonces with shares ensures that both are available or
neither. Prior, one could be yet the other may not have been (requiring an
assert in runtime to ensure we didn't bungle it somehow).

* Create helper functions for handling DkgRemoval/SubstrateSign/Sign Tributary TXs

* Move Label into SignData

All of our transactions which use SignData end up with the same common usage
pattern for Label, justifying this.

Removes 3 transactions, explicitly de-duplicating their handlers.

* Remove CurrentlyCompletingKeyPair for the non-contextual DkgKeyPair

* Remove the manual read/write for TributarySpec for borsh

This struct doesn't have any optimizations booned by the manual impl. Using
borsh reduces our scope.

* Use temporary variables to further minimize LoC in tributary handler

* Remove usage of tuples for non-trivial Tributary transactions

* Remove serde from dkg

serde could be used to deserialize intenrally inconsistent objects which could
lead to panics or faults.

The BorshDeserialize derives have been replaced with a manual implementation
which won't produce inconsistent objects.

* Abstract Future generics using new trait definitions in coordinator

* Move published_signed_transaction to tributary/mod.rs to reduce the size of main.rs

* Split coordinator/src/tributary/mod.rs into spec.rs and transaction.rs

Cache the block's events within TemporalSerai
Event retrieval was prior:
- Retrieve all events in the block, which may be hundreds of KB
- Filter to just a few

Since it's frequent to want multiple sets of events, each filtered in their own
way, this caused the retrieval to happen multiple times. Now, it only will
happen once.

Also has the scoped clients take a reference, not an owned TemporalSerai.

Move serai-client off serai-runtime, MIT licensing it
Uses a full-fledged serai-abi to do so.

Removes use of UncheckedExtrinsic as a pointlessly (for us) length-prefixed
block with a more complicated signing algorithm than advantageous.

In the future, we should considering consolidating the various primitives
crates. I'm not convinced we benefit from one primitives crate per pallet.

Remove subxt (#460)
* Remove subxt

Removes ~20 crates from our Cargo.lock.

Removes downloading the metadata and enables removing the getMetadata RPC route
(relevant to #379).

Moves forward #337.

Done now due to distinctions in the subxt 0.32 API surface which make it
justifiable to not update.

* fmt, update due to deny triggering on a yanked crate

* Correct the handling of substrate_block_notifier now that it's ephemeral, not long-lived

* Correct URL in tests/coordinator from ws to http

Add a binaries feature to the processor to reduce dependencies when used as a lib
processor isn't intended to be used as a library, yet serai-processor-tests
does pull it in as a lib. This caused serai-processor-tests to need to compile
rocksdb, which added multiple minutes to the compilation time.

dockertest 0.4 (#406)
* Updates to modern dockertest

* More updates to latest dockertest

* Update Cargo.lock to dockertest with handle restored

* clippy coordinator tests

* clippy full-stack tests

* Remove kayabaNerve branch for official repo's latest commit hash

* Update serai-client, remove reliance on the existence of a handle fn

* Don't use the hex encoding of unique_id in dockertests

Gets our hostnames just below 64 bytes, resolving test failures on at least
Debian-based systems.

* Use Network::Isolated for all dockertest instances

* Correct error from prior commit's edits

Add Batch messages from processor, verify Batchs published on-chain
Renames Update to SignedBatch.

Checks Batch equality via a hash of the InInstructions. That prevents needing
to keep the Batch in node state or TX introspect.

Replace "coin" with "network"
The Processor's coins folder referred to the networks it could process, as did
its Coin trait. This, and other similar cases throughout the codebase, have now
been corrected.

Also corrects dated documentation for a key pair is confirmed under the
validator-sets pallet.

Update to the latest subxt
Writes a custom unsigned extrinic creator due to subxt having an internal error
with the scale metadata. While the code in our scope increased, it's much more
ergonomic to our usage. We may end up rewriting most of subxt, eventually.
