Tobin C. Harding 5b86e38aea Put compiler attributes below rustdocs
It is conventional, at least within the `rust-bitcoin` organisation to
put compiler attributes _below_ the associated rustdocs.

Pull request description:

  The first 8 patches clear clippy warnings. Next we add a CI job to run clippy. Finally we add a `githooks` directory that includes running clippy, also adds a section to the README on how to use the githooks. This is identical to the text in the [open PR](https://github.com/rust-bitcoin/rust-bitcoin/pull/1044) on `rust-bitcoin` that adds githooks _without_ yet adding clippy.

  **Note**: The new clippy CI job runs and is green :)

Tobin C. Harding d64132cd4b Allow missing_safety_doc
We have a whole bunch of unsafe code that calls down to the FFI layer.
It would be nice to have clippy running on CI, these safety docs
warnings are prohibiting that. Until we can add the docs add a compiler
attribute to allow the lint.

Pull request description:

  As proposed in https://github.com/rust-bitcoin/rust-bitcoin/issues/510#issuecomment-881686342 this PR raises the MSRV to 1.41.1 it also changes the code to be Edition 2018.

  The PR contains a few things:
  * Moving to edition 2018 and fixing the imports
  * Sorting and combining imports to make them more concise
  * Replacing our c_void with `core::ffi::c_void`
  * Bumping the `rand` version to latest and modifying our `RngCore` implementations accordingly
  * Doing some small refactoring and using the new `TryInto` trait where it makes the code nicer

  If people prefer I can split this PR into multiple and/or drop some commits

Tobin C. Harding ad153d82f7 Add safety rustdoc headings
Clippy warns about unsafe code without a `# Safety` section. A bunch of
these warnings are for functions that do actually have safety docs.

Follow rustdoc convention and add a `# Safety` section for the already
existing explanations.

Tobin Harding bfd88dbd6c Move WASM const definitions to a source file
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.

Add custom Debug impl for RecoverableSignature
Currently when debug printing the `RecoverableSignature` we do so byte
by byte, this means that the output differs depending on the endianess
of the machine. If instead we serialize the signature in compact form
then the output is the same irrespective of the endianess.

With this applied the following two commands now pass:

```
cargo test test_debug_output --features=recovery

```
cross test --target powerpc-unknown-linux-gnu test_debug_output --features=recovery
```

Fixes: #375

Tobin Harding 632ecc4530 Use fully qualified path for mem
When building with --no-default-features the compiler emits:

  warning: unused import: `mem`

The call site is feature gated so we either need to feature gate the
import or use a fully qualified path. Since 'core' is quite short elect
to use the fully qualified path.

Merge rust-bitcoin/rust-secp256k1#345: Add a static immutable zero aligned type
5e6d0f1363 Switch to associated constant (Jonathan Underwood)
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()
      }
  }
  ```

Merge rust-bitcoin/rust-secp256k1#335: Implement `Hash` for `schnorrsig::Signature`
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.

Matt Corallo 940a51c2c6 Reduce cryptography usage in --cfg=fuzzing
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.
