One Round DKG (#589)
* Upstream GBP, divisor, circuit abstraction, and EC gadgets from FCMP++

* Initial eVRF implementation

Not quite done yet. It needs to communicate the resulting points and proofs to
extract them from the Pedersen Commitments in order to return those, and then
be tested.

* Add the openings of the PCs to the eVRF as necessary

* Add implementation of secq256k1

* Make DKG Encryption a bit more flexible

No longer requires the use of an EncryptionKeyMessage, and allows pre-defined
keys for encryption.

* Make NUM_BITS an argument for the field macro

* Have the eVRF take a Zeroizing private key

* Initial eVRF-based DKG

* Add embedwards25519 curve

* Inline the eVRF into the DKG library

Due to how we're handling share encryption, we'd either need two circuits or to
dedicate this circuit to the DKG. The latter makes sense at this time.

* Add documentation to the eVRF-based DKG

* Add paragraph claiming robustness

* Update to the new eVRF proof

* Finish routing the eVRF functionality

Still needs errors and serialization, along with a few other TODOs.

* Add initial eVRF DKG test

* Improve eVRF DKG

Updates how we calculcate verification shares, improves performance when
extracting multiple sets of keys, and adds more to the test for it.

* Start using a proper error for the eVRF DKG

* Resolve various TODOs

Supports recovering multiple key shares from the eVRF DKG.

Inlines two loops to save 2**16 iterations.

Adds support for creating a constant time representation of scalars < NUM_BITS.

* Ban zero ECDH keys, document non-zero requirements

* Implement eVRF traits, all the way up to the DKG, for secp256k1/ed25519

* Add Ristretto eVRF trait impls

* Support participating multiple times in the eVRF DKG

* Only participate once per key, not once per key share

* Rewrite processor key-gen around the eVRF DKG

Still a WIP.

* Finish routing the new key gen in the processor

Doesn't touch the tests, coordinator, nor Substrate yet.
`cargo +nightly fmt && cargo +nightly-2024-07-01 clippy --all-features -p serai-processor`
does pass.

* Deduplicate and better document in processor key_gen

* Update serai-processor tests to the new key gen

* Correct amount of yx coefficients, get processor key gen test to pass

* Add embedded elliptic curve keys to Substrate

* Update processor key gen tests to the eVRF DKG

* Have set_keys take signature_participants, not removed_participants

Now no one is removed from the DKG. Only `t` people publish the key however.

Uses a BitVec for an efficient encoding of the participants.

* Update the coordinator binary for the new DKG

This does not yet update any tests.

* Add sensible Debug to key_gen::[Processor, Coordinator]Message

* Have the DKG explicitly declare how to interpolate its shares

Removes the hack for MuSig where we multiply keys by the inverse of their
lagrange interpolation factor.

* Replace Interpolation::None with Interpolation::Constant

Allows the MuSig DKG to keep the secret share as the original private key,
enabling deriving FROST nonces consistently regardless of the MuSig context.

* Get coordinator tests to pass

* Update spec to the new DKG

* Get clippy to pass across the repo

* cargo machete

* Add an extra sleep to ensure expected ordering of `Participation`s

* Update orchestration

* Remove bad panic in coordinator

It expected ConfirmationShare to be n-of-n, not t-of-n.

* Improve documentation on  functions

* Update TX size limit

We now no longer have to support the ridiculous case of having 49 DKG
participations within a 101-of-150 DKG. It does remain quite high due to
needing to _sign_ so many times. It'd may be optimal for parties with multiple
key shares to independently send their preprocesses/shares (despite the
overhead that'll cause with signatures and the transaction structure).

* Correct error in the Processor spec document

* Update a few comments in the validator-sets pallet

* Send/Recv Participation one at a time

Sending all, then attempting to receive all in an expected order, wasn't working
even with notable delays between sending messages. This points to the mempool
not working as expected...

* Correct ThresholdKeys serialization in modular-frost test

* Updating existing TX size limit test for the new DKG parameters

* Increase time allowed for the DKG on the GH CI

* Correct construction of signature_participants in serai-client tests

Fault identified by akil.

* Further contextualize DkgConfirmer by ValidatorSet

Caught by a safety check we wouldn't reuse preprocesses across messages. That
raises the question of we were prior reusing preprocesses (reusing keys)?
Except that'd have caused a variety of signing failures (suggesting we had some
staggered timing avoiding it in practice but yes, this was possible in theory).

* Add necessary calls to set_embedded_elliptic_curve_key in coordinator set rotation tests

* Correct shimmed setting of a secq256k1 key

* cargo fmt

* Don't use `[0; 32]` for the embedded keys in the coordinator rotation test

The key_gen function expects the random values already decided.

* Big-endian secq256k1 scalars

Also restores the prior, safer, Encryption::register function.

Redo Dockerfile generation (#530)
Moves from concatted Dockerfiles to pseudo-templated Dockerfiles via a dedicated Rust program.

Removes the unmaintained kubernetes, not because we shouldn't have/use it, but because it's unmaintained and needs to be reworked before it's present again.

Replaces the compose with the work in the new orchestrator binary which spawns everything as expected. While this arguably re-invents the wheel, it correctly manages secrets and handles the variadic Dockerfiles.

Also adds an unrelated patch for zstd and simplifies running services a bit by greater utilizing the existing infrastructure.

---

* Delete all Dockerfile fragments, add new orchestator to generate Dockerfiles

Enables greater templating.

Also delete the unmaintained kubernetes folder *for now*. This should be
restored in the future.

* Use Dockerfiles from the orchestator

* Ignore Dockerfiles in the git repo

* Remove CI job to check Dockerfiles are as expected now that they're no longer committed

* Remove old Dockerfiles from repo

* Use Debian for monero-wallet-rpc

* Remove replace_cmds for proper usage of entry-dev

Consolidates ports a bit.

Updates serai-docker-tests from "compose" to "build".

* Only write a new dockerfile if it's distinct

Preserves the updated time metadata.

* Update serai-docker-tests

* Correct the path Dockerfiles are built from

* Correct inclusion of orchestration folder in Docker builds

* Correct debug/release flagging in the cargo command

Apparently, --debug isn't an effective NOP yet an error.

* Correct path used to run the Serai node within a Dockerfile

* Correct path in Monero Dockerfile

* Attempt storing monerod in /usr/bin

* Use sudo to move into /usr/bin in CI

* Correct 18.3.0 to 18.3.1

* Escape * with quotes

* Update deny.toml, ADD orchestration in runtime Dockerfile

* Add --detach to the Monero GH CI

* Diversify dockerfiles by network

* Fixes to network-diversified orchestration

* Bitcoin and Monero testnet scripts

* Permissions and tweaks

* Flatten scripts folders

* Add missing folder specification to Monero Dockerfile

* Have monero-wallet-rpc specify the monerod login

* Have the Docker CMD specify env variables inserted at time of Dockerfile generation

They're overrideable with the global enviornment as for tests. This enables
variable generation in orchestrator and output to productionized Docker files
without creating a life-long file within the Docker container.

* Don't add Dockerfiles into Docker containers now that they have secrets

Solely add the source code for them as needed to satisfy the workspace bounds.

* Download arm64 Monero on arm64

* Ensure constant host architecture when reproducibly building the wasm

Host architecture, for some reason, can effect the generated code despite the
target architecture always being foreign to the host architecture.

* Randomly generate infrastructure keys

* Have orchestrator generate a key, be able to create/start containers

* Ensure bash is used over sh

* Clean dated docs

* Change how quoting occurs

* Standardize to sh

* Have Docker test build the dev Dockerfiles

* Only key_gen once

* cargo update

Adds a patch for zstd and reconciles the breaking nightly change which just
occurred.

* Use a dedicated network for Serai

Also fixes SERAI_HOSTNAME passed to coordinator.

* Support providing a key over the env for the Serai node

* Enable and document running daemons for tests via serai-orchestrator

Has running containers under the dev network port forward the RPC ports.

* Use volumes for bitcoin/monero

* Use bitcoin's run.sh in GH CI

* Only use the volume for testnet (not dev)
