Doesn't yet act on it in coordinator.
* Move txn usage as needed for stable Rust to build
* Correct InvalidDkgShare serialization
If a user transferred in without an InInstruction, and the amount exactly
matched a forwarded output, the user's output would fulfill the
forwarding. Then the forwarded output would come along, have no InInstruction,
and be refunded (to the prior multisig) when the user should've been refunded.
Adding this new address type resolves such concerns.
The higher-level scanner code in multisigs/mod.rs now creates a series of plans
with limited context. These include forwarding and refunding plans, moving all
handling of forwarding flags on the scanner's clock and therefore safe.
Also simplifies the refunding a decent bit.
This code is still largely designed around the idea a payment for a network is
fungible with any other, which isn't true. This starts moving past that.
Asserts are added to ensure the integrity of coin to the scheduler (which is
now per key per coin, not per key alone) and in Bitcoin/Monero prepare_send.
The prior system spawned a new connection per request to enable parallelism,
yet kept hitting hyper::IncompleteMessages I couldn't track down. This
attempts to resolve those by a long-lived socket.
Halves the amount of requests per-authenticated RPC call, and accordingly is
likely still better overall.
I don't believe this is resolved yet but this is still worth pushing.
Removes bitcoin-serai's usage of sha2 for bitcoin-hashes. While sha2 is still
in play due to modular-frost (more specifically, due to ciphersuite), this
offers a bit more performance (assuming equivalency between sha2 and
bitcoin-hashes' impl) due to removing a static for a const.
Makes secp256k1 a dev dependency for bitcoin-serai. While secp256k1 is still
pulled in via bitcoin, it's hopefully slightly better to compile now and makes
usage of secp256k1 an implementation detail of bitcoin (letting it change it
freely).
Also offers slightly more efficient signing as we don't decode to a signature
just to re-encode for the transaction.
Removes a 20s sleep for a check every second, up to 20 times, for reduced test
times in the processor.

* Update the coordinator to give key shares based on weight, not based on existence
Participants are now identified by their starting index. While this compiles,
the following is unimplemented:
1) A conversion for DKG `i` values. It assumes the threshold `i` values used
will be identical for the MuSig signature used to confirm the DKG.
2) Expansion from compressed values to full values before forwarding to the
processor.
* Add a fn to the DkgConfirmer to convert `i` values as needed
Also removes TODOs regarding Serai ensuring validator key uniqueness +
validity. The current infra achieves both.
* Have the Tributary DB track participation by shares, not by count
* Prevent a node from obtaining 34% of the maximum amount of key shares
This is actually mainly intended to set a bound on message sizes in the
coordinator. Message sizes are amplified by the amount of key shares held, so
setting an upper bound on said amount lets it determine constants. While that
upper bound could be 150, that'd be unreasonable and increase the potential for
DoS attacks.
* Correct the mechanism to detect if sufficient accumulation has occured
It used to check if the latest accumulation hit the required threshold. Now,
accumulations may jump past the required threshold. The required mechanism is
to check the threshold wasn't prior met and is now met.
* Finish updating the coordinator to handle a multiple key share per validator environment
* Adjust stategy re: preventing noce reuse in DKG Confirmer
* Add TODOs regarding dropped transactions, add possible TODO fix
* Update tests/coordinator
This doesn't add new multi-key-share tests, it solely updates the existing
single key-share tests to compile and run, with the necessary fixes to the
coordinator.
* Update processor key_gen to handle generating multiple key shares at once
* Update SubstrateSigner
* Update signer, clippy
* Update processor tests
* Update processor docker tests
Even though the intent was to test against 0.17.3.2, and a Monero 0.17.3.2 node
was running, the processor now uses docker which will always use 0.18.
Accordingly, while the intent was valid, it was pointless.
This is unfortunate, as testing against 0.17 helped protect against edge cases.
The infra to preserve their tests isn't worth the benefit we'd gain from said
tests however.
The lack of locking the connection when making an authenticated request, which
is actually two sequential requests, risked another caller making a request in
between, invalidating the state.
Now, only unauthenticated connections share a connection object.
Disables the unused zmq RPC.
Removes authentication which seems to be unstable as hell when under load
(see #351).
No longer use Network::Isolated as it's not needed here (the Monero nodes run
with `--offline`).
Also halves the minimum fee policy, which still may be 2x-4x higher than
necessary due to API limitations within bitcoin-serai (which we can fix as it's
within our scope).
Monero would select decoys with a new RNG seed, which may have used more bytes,
increasing the fee.
There's a few comments here.
1) Non-determinism wasn't removed via distinguishing the edits. It was done by
removing part of the transcript. A TODO exists to improve this.
2) Distinct TX fees is a test failure, not an issue in prod *unless* the distinct
fee is greater. So long as the distinct fee is lesser, it's fine.
3) Removing outputs is expected to only decrease fees.
The existing code should've mostly handled this fine. Only a single edge case
(TX fee reduction on no-change Plans) would cause an improper increase in
operating costs.
