2f833dec77 Add job to competently check MSRVs
The prior workflow (now deleted) required manually specifying the packages to
check and only checked the package could compile under the stated MSRV. It
didn't verify it was actually the _minimum_ supported Rust version. The new
version finds the MSRV from scratch to check if the stated MSRV aligns.

Updates stated MSRVs accordingly.

Also removes many explicit dependencies from secq256k1 for their re-exports via
k256. Not directly relevant, just part of tidying up all the `toml`s.

3c664ff05f Re-arrange coordinator/
coordinator/tributary was tributary-chain. This crate has been renamed
tributary-sdk and moved to coordinator/tributary-sdk.

coordinator/src/tributary was our instantion of a Tributary, the Transaction
type and scan task. This has been moved to coordinator/tributary.

The main reason for this was due to coordinator/main.rs becoming untidy. There
is now a collection of clean, independent APIs present in the codebase.
coordinator/main.rs is to compose them. Sometimes, these compositions are a bit
silly (reading from a channel just to forward the message to a distinct
channel). That's more than fine as the code is still readable and the value
from the cleanliness of the APIs composed far exceeds the nits from having
these odd compositions.

This breaks down a bit as we now define a global database, and have some APIs
interact with multiple other APIs.

coordinator/src/tributary was a self-contained, clean API. The recently added
task present in coordinator/tributary/mod.rs, which bound it to the rest of the
Coordinator, wasn't.

Now, coordinator/src is solely the API compositions, and all self-contained
APIs are their own crates.

05dc474cb3 Correct std feature-flagging
If a crate has std set, it should enable std for all dependencies in order to
let them properly select which algorithms to use. Some crates fallback to
slower/worse algorithms on no-std.

Also more aggressively sets default-features = false leading to a *10%*
reduction in the amount of crates coordinator builds.

39ce819876 Slash malevolent validators (#294)
* add slash tx

* ignore unsigned tx replays

* verify that provided evidence is valid

* fix clippy + fmt

* move application tx handling to another module

* partially handle the tendermint txs

* fix pr comments

* support unsigned app txs

* add slash target to the votes

* enforce provided, unsigned, signed tx ordering within a block

* bug fixes

* add unit test for tendermint txs

* bug fixes

* update tests for tendermint txs

* add tx ordering test

* tidy up tx ordering test

* cargo +nightly fmt

* Misc fixes from rebasing

* Finish resolving clippy

* Remove sha3 from tendermint-machine

* Resolve a DoS in SlashEvidence's read

Also moves Evidence from Vec<Message> to (Message, Option<Message>). That
should meet all requirements while being a bit safer.

* Make lazy_static a dev-depend for tributary

* Various small tweaks

One use of sort was inefficient, sorting unsigned || signed when unsigned was
already properly sorted. Given how the unsigned TXs were given a nonce of 0, an
unstable sort may swap places with an unsigned TX and a signed TX with a nonce
of 0 (leading to a faulty block).

The extra protection added here sorts signed, then concats.

* Fix Tributary tests I broke, start review on tendermint/tx.rs

* Finish reviewing everything outside tests and empty_signature

* Remove empty_signature

empty_signature led to corrupted local state histories. Unfortunately, the API
is only sane with a signature.

We now use the actual signature, which risks creating a signature over a
malicious message if we have ever have an invariant producing malicious
messages. Prior, we only signed the message after the local machine confirmed
it was okay per the local view of consensus.

This is tolerated/preferred over a corrupt state history since production of
such messages is already an invariant. TODOs are added to make handling of this
theoretical invariant further robust.

* Remove async_sequential for tokio::test

There was no competition for resources forcing them to be run sequentially.

* Modify block order test to be statistically significant without multiple runs

* Clean tests

While I don't love the introduction of empty_signed, it's practically fine.
