Currently we are defining the WASM integer size and alignments in the
`stdio.h` header file, this is wrong because this file is included in
the build by way of `build.rs` as well as by upstream `libsecp256k1`.
Move WASM integer definitions to a `C` source file and build the file
into the binary if target is WASM.
c1bb316675 Make global-context-less-secure actually enable the global context (Elichai Turkel)
Pull request description:
In #407 we restored the `global-context-less-secure` feature, but it didn't actually do anything because #385 changed all the cfg checks on the whole module to depend on `global-context`, so we need to enable `global-context` in order to make that module compile.
so before all this, users could enable *just* `global-context-less-secure` without enabling the `global-context`, and after this PR it will behave the same.
(this will not enable the randomization because of: 1cf2429b12/src/context.rs (L51))

f93ca81348 Add sign_ecdsa_with_noncedata and sign_ecdsa_recoverable_with_noncedata (junderw)
Pull request description:
Fixes#424
As discussed on [IRC](https://gnusha.org/bitcoin-rust/2022-03-19.log) (starts at 09:14).
These methods will allow for users to generate multiple signatures with the same private key and message by utilizing one of the `Variants` mention in RFC6979 which is exposed by libsecp256k1 via the `noncedata` argument.
The reasoning behind adding this is to allow our library to migrate from using the -sys crate. Currently we support using this noncedata argument, and would like to continue doing so while at the same time migrating away from -sys crate.

de65fb2f1e Implement de/serialization for SharedSecret (Tobin Harding)
Pull request description:
As we do for other keys implement serde de/serialization for the `SharedSecret`.
Please note, this adds `from_slice` and `from_bytes` (borrowed and owner respectively) because I needed to use them. Doing so treads on @dspicher's toes because he is in the process of implementing an owned conversion method for `SharedSecret`. The fair thing to do would be let https://github.com/rust-bitcoin/rust-secp256k1/pull/417 resolve and merge before merging this one (I can rebase).
~Side note, its kind of rubbish that `BytesVisitor` deserializes into a buffer (presumably) then we reallocate and copy the buffer to use the borrowed conversion method due to the serde function signature `fn visit_bytes<E: de::Error>(self, v: &[u8]) -> Result<Self::Value, E>`~ (I was bumbling nonsense.)

- Remove the `wasm` job, replace it by enabling the `DO_WASM` env var for the stable toolchain run in the `Tests` job.
- Add `--cfg docrs` flag to the docs build and set the `DO_DOCS` env var as part of the nightly toolchain run in `Tests` job.

Currently we use 'no default features' for the `bitcoin_hashes`
dependency. Doing so means that if users want the `std` feature they
need to explicitly add a `bitcoin_hashes` dependency even though we
re-export `bitcoin_hashes` as `hashes`. This means that in the common
case the re-export is pointless. As an example, `rust-bitcoin`
unnecessarily requires an explicit dependency on `bitcoin_hashes`.
Add `bitcoin-hashes-std` feature so that users do not need an explicit
dependency in the common use case.
Change the test matrix to only test '*-std' features when 'std' is
enabled since enabling one without the other is illogical. Please note,
this replaces the test run of feature 'std'+'rand'+'rand-std' with just
'std'+'rand-std' because enabling 'rand-std' enables 'rand' so the
explicit additional feature is redundant.

the real secret, this is sub-optimal. We have a solution for other
secrets in the project where printing is obfuscated and we provide a
`display_secret` method for explicitly printing.
Mirror the logic for other secrets and obfuscate the `SharedSecret` when printing.
Improve rustdocs on `display_secret` by doing:
- Minor improvements to the rustdocs to aid readability in the editor.
- Do not guarantee (`assert_eq!`) debug output
The `serialize_secret` method is a getter method, it does not do any
serialisation. However we use the method on secret keys and key types so
in order for the name to be uniform use the descriptive name
`secret_bytes`.
Rename `serialize_secret` to be `secret_bytes`.
The identifier `i` is predominantly used for indexing an array but we
are using it as a place holder for the iterated value of an array that
is then printed. The identifier `byte` is more descriptive.
Done in preparation for adding similar code to the `ecdh` module.
In array initialisation we use magic number 64, this is the secret bytes
length multiplied by 2.
Please note; we still use the magic number 32, left as such because it
is used in various ways and its not immediately clear that using a
single const would be any more descriptive.
Use `SECRET_KEY_SIZE * 2` instead of magic number 64.
Hashing the debug output for secrets can be done with `bitcoin_hashes`
not just `std`. Mention this in the obfuscated string output when
neither are available.

834f63c26c Separate new_with_hash into public function (Tobin Harding)
Pull request description:
Currently `SharedSecret` provides a way to get a shared secret using SHA256 _as well as_ a way to use a custom hash function to get the shared secret. Internally `SharedSecret` uses a 256 byte buffer, this is a tad wasteful. We would like to keep the current functionality but reduce memory usage.
- Patch 1: Pulls the `new_with_hash` logic out into a standalone public function that just returns the 64 bytes representing the x,y co-ordinates of the computed shared secret point. Callers are then responsible for hashing this point to get the shared secret (idea by @Kixunil, thanks).
- Patch 2: Does trivial refactor
- Patch 3: Uses a 32 byte buffer internally for `SharedSecret`. This is basically a revert of the work @elichai did to add the custom hashing logic. @elichai please holla if you are not happy with me walking all over this code :)

The `SharedSecret` uses sha256 to hash the secret, this implies the
secret is 32 bytes of data.
Currently we use a buffer of 256 bytes, this is unnecessary.
Change the implementation of `SharedSecret` to use a 32 byte buffer.
In test code we use multiple pub/sec keys. It is more intuitive if the
'secret 1' is generated by the owner of secret key 1.
Refactor only, no logic changes.
In preparation for simplifying the `SharedSecret` internals pull the
`new_with_hash` function logic out into a standalone public function
that provides similar functionality without use of the `SharedSecret`
struct. Function now returns the 64 bytes of data representing a shared
point on the curve, callers are expected to the hash these bytes to get
a shared secret.
