This patch adds a declaration of the `ecdsa_parse_compact` function to
util.h. This function isn't called from within libsecp proper; it is
called in lax_der_parse.c (which we patch separately with a declaration)
and in example code (which we don't compile at all).

e9e17a0039 Check for changes to the public API (Tobin C. Harding)
Pull request description:
We would like to get to a stage where we can commit to the public API. To help us achieve this add a script that generates the public API and checks it against three committed files, one for each feature set: no features, alloc, std.
The idea is that with this applied any PR that changes the public API should include a final patch that is just the changes to the api/*.txt files, that way reviewers can discuss the changes without even needing to look at the code, quickly giving concept ACK/NACKs. We also run the script in CI to make sure we have not accidentally changed the public API so that we can be confident that don't break semver during releases. The script can also be used to diff between two release versions to get a complete list of API changes, useful for writing release notes and for users upgrading.
There is a development burden involved if we apply this patch.

39febcb866 Create rust-bidings (Davidson Souza)
Pull request description:
~**Marking as draft as this is an unreleased feature from libsecp**~
From upstream:
This implements encoding of curve points using the ElligatorSwift algorithm, using 4 new API calls:
secp256k1_ellswift_encode, which converts a public key to a 64-byte pseudorandom encoding.
secp256k1_ellswift_decode, the reverse operation to convert back to normal public keys.
secp256k1_ellswift_create, which can be seen as a combination of secp256k1_ec_pubkey_create + secp256k1_ellswift_encode, but is somewhat safer.
secp256k1_ellswift_xdh, which implements x-only Diffie-Hellman directly on top of 64-byte encoded public keys, and more efficiently than decoding + invoking normal ECDH.
This algorithm allows mapping any pair of field elements (u, t) to a (valid) x coordinate in the curve. This allows representing a field element as a 64-bytes bit string that is indistinguishable from random. You can build a pair of (u, t) from any group element as well.
We also have an integrated x-only ECDH that can be used to establish a shared secret between two parties. All algorithms are compatible with BIP324 and are tested against the BIP's test cases.
I have a few questions about the rust side of the implementation:
Should it be always on, or leave it behind a cargo feature? In `libsecp` this module is default on, but you can disable it.
I'm not exposing the low-level functions, instead you can use high-level types to interact with ellswift. Is it reasonable to also expose a safe version of the functions above?

MIPS was recently downgraded to Tier 3, which means it won't be installable by
rustup and may not work as expected. This commit removes all MIPS-related
CI jobs.
This is just a bad test. It constructs a preallocated context object by
starting from a non-preallocated context object, in a way that can't be
done by users (since it directly constructs a `Secp256k1` struct) and a
way that is very difficult to unwind, because you wind up with two
pointers to the same underlying context object, one a "preallocated" one
and one a normal one.
If you then drop the preallocated one, it will call
`secp256k1_context_destroy`, forcing you to manually deallocate the
other one. If you drop the normally-allocated one, you need to
mem::forget the preallocated one to avoid calling
`secp256k1_context_destroy` twice. The whole thing is pretty fragile.
There is another unit test, `test_raw_ctx`, which gets into the same
situation but using the public API, and demonstrates a few ways to get
out of it.
upstream libsecp now has a CMakeLists.txt file. Many years ago we added
some things to .gitignore which appear to be local developers committing
the names of their own stray files, and now this is causing the
revendoring script to lose track of vendored files.

Now that we have `hashes` as the crate name of `bitcoin_hashes` we can
slightly clean up the import statements.
This is based on the convention we have to import things directly from
the crate if we depend on it and not from the crate level re-export.
Use the more terse `hashes` by way of the `package` field in the
manifest.

The `wasm-pack` command does not honour `cargo` flags passed to it so we
cannot use `--locked` and test against pre-made lock files. Instead just
run the WASM test from the test script wrapper.
We would like to be able to run the test script with different lock
files, in preparation for doing so move the `test.sh` script to
`_test.sh` and add a new `test.sh` that runs `_test.sh`.
Keep the outer script as `test.sh` so that we do not change the workflow
for those running the script including the github actions.
A while back we added two lock files that were to track dependencies of
two successful test runs, one with a minimal set of dependencies and one
with a recent set of dependencies (ie, recent dependency versions). We
never used these lock files in CI however.
In preparation for using the lock files in CI, and in order to be
uniform with `rust-bitcoin`, move the lock files to the crate root and
rename them to:
- Cargo-minimal.lock
- Cargo-recent.lock

cd40ae7f19 Improve Message constructors (Tobin C. Harding)
Pull request description:
Observe:
- The word "hash" can be a verb or a noun, its usage in function names is therefore at times ambiguous.
- The function name `from_slice` gives no indication as to what the slice input is.
Improve Message constructors by doing:
- Add a constructor `Message::from_digest` that takes a 32 byte array as input.
- Rename `Message::from_slice` to `Message::from_digest_slice` (deprecate `from_slice` and add `from_digest_slice`)
- Improve the docs while we are at it.
### Note
The original PR conflate 2 separate issues, the `Message` constructor naming clarity issue and the upgrade difficulty issue, PR is now only a solution to the first. The second will be done as a separate PR.
