The public key is unrelated to the signature algorithm. It will
be moved out of the module in another commit. For ease of review,
the renamed is kept separate.
With the introduction of Schnorr signatures, exporting a `Signature`
type without any further qualification is ambiguous. To minimize the
ambiguity, the `ecdsa` module is public which should encourage users
to refer to its types as `ecdsa::Signature` and `ecdsa::SerializedSignature`.
To reduce ambiguity in the APIs on `Secp256k1`, we deprecate several
fucntions and introduce new variants that explicitly mention the use of
the ECDSA signature algorithm.
Due to the move of `Signature` and `SerializedSignature` to a new module,
this patch is a breaking change. The impact is minimal though and fixing the
compile errors encourages a qualified naming of the type.
75b49efb3d Implement `Hash` for all array newtypes (elsirion)
Pull request description:
I pondered putting the impl into the array type macro together with `(Partial)Eq`, but that would have meant removing other implementations and potentially implementing it for types where it is not wanted. The drawback of the separate impl is that it is more disconnected from the `(Partial)Eq` impl and could theoretically diverge (although unlikely in case of such a simple type) which would break the trait's contract.

f1bdee210a add cross testing on rust tier 1 and tier 2 with host tools (Riccardo Casatta)
Pull request description:
After working on https://github.com/rust-bitcoin/rust-bitcoin/pull/627 I thought it may be simple and useful to use [cross](https://github.com/rust-embedded/cross) environment to test across different architectures and started here.
So I took all rust tier1 and tier2 with Host tools archictectures and added to the test matrix, run here https://github.com/RCasatta/rust-secp256k1/actions/runs/985791240.
Errors on darwin are due to the environment because it works fine on physical machine, however errors on illumos and netbsd maybe are useful to know?

24d6f62603 Use explicit u8 when assigning a byte slice (junderw)
Pull request description:
Is there a way to tell the compiler to not allow `[0; 64]` and require that either the type is explicitly given to the variable, or that each member uses explicit `0u8` notation?
I noticed the usage was a mix of explicit and implicit, so I changed all to explicit.

This reduces the usage of real cryptography in --cfg=fuzzing,
specifically replacing the secret->public key derivation with a
simple copy and ECDH with XOR of the public and private parts
(plus a stream of 1s to make a test pass that expected non-0
output).
It leaves secret tweak addition/multiplication as-is.
It also changes the context creation to over-allocate and store
the context flags at the end of the context buffer, allowing us
to easily test context flags in each function.
While it would be nice to have something fancier (eg XOR-based),
its not immediately obvious how to accomplish this, and better to
fix the issues I have than spend too much time on it.
Fixes#271.
This partially reverts b811ec133a
In the next commit the secret->public key derivation in fuzzing cfg
is changed to be simpler, as well as the validity rules of public
keys relaxed.
This adds a new test to ensure random keys can be added, not just
the hard-coded keys test that exists today.
