Pull request description:
Sorry for getting another point release. This time I have tested against this branch for rust-bitcoin https://github.com/rust-bitcoin/rust-bitcoin/pull/755. Hopefully, this is the last release.
Next release, we should have a Release Candidate for a couple of days before publishing a release.

e595b39510 Re-export Parity struct (sanket1729)
Pull request description:
pub struct Parity is under a private module key and not re-exported in lib.rs . It is therefore not
possible to use it downstream.

Pull request description:
Two functions in the FFI secp code return and accept a parity integer.
Currently we are manually converting this to a bool. Doing so forces readers of the code to think what the bool means even though understanding this value is not needed since in is just passed back down to the FFI code.
We initially tried to solve this issue by adding an enum, discussion below refers to that version. Instead of an enum we can solve this issue by adding an opaque type that holds the parity value returned by the FFI function call and then just pass it back down to FFI code without devs needing to know what the value should be. This fully abstracts the value away and removes the boolean conversion code which must otherwise be read by each dev.
- Patch 1 and 2 improve unit tests that test the code path modified by this PR
- Patch 3 trivially changes code to be uniform between two similar methods (`tweak_add_assign`)
- Patch 4 is the meat and potatoes (main part of PR :)
- Patch 5 is docs improvements to code in the area of this PR

It is not immediately apparent what 'err == 1' means, one must determine
that the FFI function call returns 1 for success. We can help readers of
the code by adding a 'Return' section to the method documentation.
Add trailing full stop to method docs initial line also.
Two functions in the FFI secp code return and accept a parity int.
Currently we are manually converting this to a bool. Doing so forces
readers of the code to think what the bool means even though
understanding this bool is not needed since in is just passed back down

hold the original int and not converting it to a boolean value.
Add 'Return' and 'Error' sections to `tweak_add_assign` while fixing the
docs to describe the new opaque parity type.
We have two `tweak_add_assign` methods (one for keypair and one for
x-only pubkey). Both check the return value from a FFI function call.
We can make both sites uniform to _slightly_ reduce cognitive load when
reading the code.
Use C style code to make it obvious to readers that this is basically C
code.
There are currently two unit tests in the `schnorr` module that are
testing keys from the `key` module. This is possible because the tests
are only testing the public interface, none the less they are better
placed in the `key` module.
The import statements can be simplified by using an import
wildcard (`super::*`). While we are at it put them in std, external
crate, this crate order.

9cf552e240 Add a static immutable zero aligned type (junderw)
Pull request description:
The `zeroed` fn can not be used in static assignments.
In environments where it is no_std and no allocator are present, the only way to get a slice of AlignedTypes is dynamically, so `preallocated_gen_new` can't be used.
By offering this as a static, it can be used in static assignments as such:
```rust
#[cfg(target_pointer_width = "32")]
static mut CONTEXT_BUFFER: [AlignedType; 69645] = [ZERO_ALIGNED; 69645];
#[cfg(target_pointer_width = "64")]
static mut CONTEXT_BUFFER: [AlignedType; 69646] = [ZERO_ALIGNED; 69646];
static mut SECP256K1: Option<Secp256k1<AllPreallocated>> = None;
pub fn get_context(seed: Option<&[u8; 32]>) -> &'static Secp256k1<AllPreallocated<'static>> {
unsafe {
if SECP256K1.is_none() {
SECP256K1 = Some(
Secp256k1::preallocated_gen_new(&mut CONTEXT_BUFFER)
.expect("CONTEXT_BUFFER size is wrong"),
);
}
if let Some(seed) = seed {
SECP256K1.as_mut().unwrap().seeded_randomize(seed);
}
SECP256K1.as_ref().unwrap()
}
}
```

Pull request description:
This patch-set tries to re-structure the library a bit. What we currently have seems to have been mostly driven by historical growth. For example, with the addition of Schnorr signatures, just exposing `secp256k1::Signature` is ambiguous.
This PR only contains renames and moving around of code. I've tried to structure the patches in such a way that makes this reasonably easy to review. Feedback welcome!

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?

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.
