Merge rust-bitcoin/rust-bitcoin#1420: Allow dead_code/unused_imports when fuzzing
5a2a37d4be Allow dead_code/unused_imports when fuzzing (Tobin C. Harding)

Pull request description:

  Littering the codebase with `#[cfg(not(fuzzing))]` is a bit messy just to quieten the linter during fuzzing. Instead just globally allow.

  Done while debugging #1409

Merge rust-bitcoin/rust-bitcoin#1509: Use dtonlnay instead of actions-rs
4201612837 Use dtonlnay instead of actions-rs (Tobin C. Harding)

Pull request description:

  Done on top of #1508

  Currently we use the `actions-rs` GitHub action to run our tests. It seems the project is now unmaintained [0].

  Well known Rust developer dtonlnay maintains a GitHub action that can be used instead.

  Replace all uses of `actions-rs/toolchain` with `dtonlnay/rust-toolchain`. Note that with the new action there is no way to configure the toolchain, instead a different `uses` statement is required - this means we have to split our jobs up by toolchain. This is arguably cleaner anyways.

  Note that with this patch applied the "no-std" tests are now _not_ run for MSRV since we explicitly support "no-std" only for the 1.47 and above toolchains - strange that this was working?

locktime: Add inline to public functions
Add `#[inline]` to all public functions/methods excluding error types
and `Display` impls. Error paths do not need to be fast and presumably
`Display` is called on code paths that do IO so this also does not need
to be fast.

Merge rust-bitcoin/rust-bitcoin#1502: Fix bug in `ScriptBuf::extend` for short iterators
920599da94 Add test for previous commit (Martin Habovstiak)
a7f3458c27 Fix bug in `ScriptBuf::extend` for short iterators (Martin Habovstiak)

Pull request description:

  `ScriptBuf::extend` contained an optimization for short scripts that was
  supposed to preallocate the buffer and then fill it. By mistake it
  attempted to fill it from already-exhausted iterator instead of the
  temporary array it drained the items into. This obviously produced
  garbage (empty) values.

  This was not caught by tests because the optimization is only active for
  scripts with known maximum length and the test used `Instructions` which
  doesn't know the maximum length.

8ce928b8e7 Add testing section to readme (Tobin C. Harding)
2e79a0bdc4 Introduce mutation testing (Tobin C. Harding)

Pull request description:

  Introduce mutation testing by way of mutagen [0] (see #1484 for context).

  - Conditionally add the dev-dependency `mutagen` (using `do_mutate` flag)

      This flag is not very well named but `mutagen` and `mutate` are already taken?

  - Mutate all methods of the `U256` struct that do not require additional unit tests.

      Uses `cfg(all(test, do_mutate), mutate)` - I cannot workout why we need to check on `test` as well i.e., I don't understand why we cannot use `cfg(do_mutate, mutate)`?

  With this applied test can be run as usual with a stable toolchain. To run mutagen we use `RUSTFLAGS='--cfg=do_mutate' cargo +nightly mutagen` (doing so runs 29 mutants).

* Use `TryFrom` instead of `From` for fallible conversions
* Move byte conversion methods from `impl_array_newtype` to
  `impl_bytes_newtype`
* Add missing trait impls like `AsRef`, `Borrow`, their mutable versions
  and infallible conversions from arrays

Martin Habovstiak 3e520f9094 Use hex from internals rather than hashes
`bitcoin-internals` contains a more performant implementation of hex
encoding than what `bitcoin_hashes` uses internally. This switches the
implementations for formatting trait implementations as a step towards
moving over completely.

The public macros are also changed to delegate to inner type which is
technically a breaking change but we will break the API anyway and the
consuers should only call the macro on the actual hash newtypes where
the inner types already have the appropriate implementations.

Apart from removing reliance on internal hex from public API this
reduces duplicated code generated and compiled. E.g. if you created 10
hash newtypes of SHA256 the formatting implementation would be
instantiated 11 times despite being the same.

To do all this some other changes were required to the hex
infrastructure. Mainly modifying `put_bytes` to accept iterator (so that
`iter().rev()` can be used) and adding a new `DisplayArray` type. The
iterator idea was invented by Tobin C. Harding, this commit just adds a
bound check and generalizes over `u8` and `&u8` returning iterators.

While it may seem that `DisplayByteSlice` would suffice it'd create and
initialize a large array even for small arrays wasting performance.
Knowing the exact length `DisplayArray` fixes this.

Another part of refactoring is changing from returning `impl Display` to
return `impl LowerHex + UpperHex`. This makes selecting casing less
annoying since the consumer no longer needs to import `Case` without
cluttering the API with convenience methods.

Merge rust-bitcoin/rust-bitcoin#1155: Implemented unsized `Script`
8e428562cb Implemented unsized `Script` (Martin Habovstiak)

Pull request description:

  This renames `Script` to `ScriptBuf` and adds unsized `Script` modeled
  after `PathBuf`/`Path`. The change cleans up the API a bit, especially
  all functions that previously accepted `&Script` now accept truly
  borrowed version. Some functions that perviously accepted `&[u8]` can
  now accept `&Script` because constructing it is no loger costly.

  This is a more idiomatic alternative to #884 with two unavoidable lines of `unsafe` copied from `std`.

  Closes #522
  Closes #949

  (For 949, we allow users to use whichever they like but still use `ScriptBuf` in `Transaction`.)

Pull request description:

  This is potentially a controversial PR, but hear me out. My argument is that right now `absolute::LockTime` and `PackedLockTime` are basically identical types; they can be converted between each other with `From` and they have exactly the same semantics except that `PackedLockTime` has `Ord` on it. This makes it very confusing to tell which one should be used, for example in PSBT2 where there are now extra locktime-related fields.

  The motivation for having `PackedLockTime` independent of `LockTime` are:
  * `PackedLockTime` is theoretically more efficient because you don't need to unpack the field, don't need to store a enum discriminate, etc. I don't buy this. If you are trying to save individual bytes in your transaction-parsing there are lots of places you'd look before messing around with locktimes, so we shouldn't privilege this specific thing.
  * `PackedLockTIme` has an `Ord` impl, and removing that will have a cascading effect on transactions, blocks, etc., preventing them from being held in `BTreeMaps` etc. **My proposal**, implemented here, is to just manually impl `Ord` on `Transaction` and don't impl it on `LockTime`.

  I recall some argument that we need to be able to sort miniscripts, and miniscripts might have locktimes in them, but I think this is wrong -- miniscripts always have explicitly either a `Height` or a `Time`, and there is no problem ordering these.

Tobin C. Harding 56e4e53357 hashes: ci: Remove --all
Currently we are using the `--all` flag in `cargo` commands in the
`hashes` CI script. This flag (the deprecated version of `--workspace`)
causes cargo to run the command for the whole workspace, this is not
what we want because we run test individually for each crate using a ci
script per crate.

The effect of this patch is to reduce re-runs of tests i.e., reduce
machine usage during CI runs with no reduction of coverage - PROFIT!

Merge rust-bitcoin/rust-bitcoin#1450: hashes: Do not implement `Deref`
b7a84d0c68 hashes: Do not implement Deref (Tobin C. Harding)

Pull request description:

  Currently we implement `Deref` for hashes. From the docs [0]

   > Deref should only be implemented for smart pointers to avoid confusion

  Furthermore because we implement `Deref` as well as implement `internals::hex::display::DisplayHex` for slices hashes get coerced into slices and `to_lower_hex_string` can be called on them, this is incorrect because `DisplayHex` does not account for hashes that display backwards so we end up with the wrong string.

  This is an API breaking change, and I have not built any other crates in our stack to check if anything breaks.
