fe828d040d add redundant features for cargo 1.41 bug (Andrew Poelstra)
Pull request description:
It looks like cargo versions up to 1.45 have a bug that sometimes causes dependency resolution to fail. There is a straightforward, somewhat ugly fix, which this PR implements.
In #571 we implemented this and rush-merged it into 0.24.x because (a) it was breaking our CI, (b) it was clearly harmless, even if it turn out not to be the best decision. For this PR I'd like somebody other than me and Sanket to take a look and sanity check us.
If we merged this, it will also need a backport to 0.25.x.
For more details see #571 and the linked issues there.

Trying to do some fuzz testing I noticed that I had omitted to add `secp256k1_schnorrsig_sign_custom` to the `fuzz_dummy` module of `secp256k1sys` crate in #440. This PR adds it. I just forwarded the call to `secp256k1_schnorrsig_sign` as I didn't have any better idea but open to suggestions.

1d6a46eb6d change bitcoin-hashes feature gates to bitcoin_hashes (Andrew Poelstra)
Pull request description:
This leaves `bitcoin-hashes` in place everywhere in the documentation, but changes it to `bitcoin_hashes` on the actual feature gates, to ensure that both flags work.
It's unfortunately a bit hard to test this because the library will be self-consistent pretty-much no matter what we do ... the issue is if the user enables the wrong flag we want to make sure that all the APIs we intend to be visible are actually visible.

Recently we found and fixed an unsoundness issue in the
`preallocated_gen_new` function. As we have yet to release 0.25.0 we can
just update the changelog to reflect the newly merged fix.
As is customary add a newline between rustdoc heading and content. Done
so that the code is identical to other released code (during backport
the space was added).

f961497e69 context: introduce unsafe `PreallocatedContext` trait (Andrew Poelstra)
Pull request description:
Stop this from being a generic function over all contexts, to only a function generic over contexts where we can bound the lifetime precisely. Introduces a new unsafe trait. I *believe* the only code this breaks was already unsound:
* code that tried to use one of the `*Preallocated` context markers with an incorrect lifetime
* code that tried to use `preallocated_gen_new` with a non-`*Preallocated` marker, which I believe we allowed before (I just noticed this now) and almost certainly would've led to UB on drop

9b07e8e8c5 secp-sys: Use NonNull in API instead of *mut T (Tobin C. Harding)
Pull request description:
Currently we expect non-null pointers when we take `*mut T` parameters, however we do not check that the pointers are non-null because we never set VERIFY in our C build. We can use the `NonNull` type to enforce no-null-ness as long as we use `NonNull::new`. In a couple of instances we manually check that a buffer is not empty and therefore that the pointer to it is non-null so we can safely use `NonNull::new_unchecked`.
Replace mutable pointer parameters `*mut T` (e.g. `*mut c_void`) and return types with `NonNull<T>`.
Fix#546
### Note
The description above fully explains the issue to the best of my knowledge, if the description is not spot on then I'm not fully understanding the issue. Please correct me if this is the case.
> One unfortunate thing is that this means that we wouldn't be able to implement CPtr for secp256k1::Context, which is our designated "expose types from secp256k1-sys which is not stable" semver escape hatch.
You've lost me here? `secp256k1::Context` is a trait did you mean `secp256k1::Secp256k1` or `secp256k1_sys::Context`?

Fixes unsoundness in `preallocated_gen_new` which previously did not
properly constrain the lifetime of the buffer used to back the context
object. We introduce an unsafe marker trait, and impl it for our
existing preallocated-context markers.
Annoyingly the trait has to be public even though it should never be
used directly, and is only used alongside the sealed `Context` trait,
so it is de-facto sealed itself.

we have wrapper functions to handle symbol renaming we essentially have
duplicate functions i.e., they require the same docs, instead of

Also add attribute to stop the linter warning about the missing safety
