cf9733d678 Verify and fix mul_u64 (Tobin C. Harding)
Pull request description:
Add kani verification for `U256::mul_u64`, doing so uncovered a bug in the current implementation due to overflow. Re-write the `mul_u64` method.
Fix: #1497
## Note
This PR now _only_ tests `mul_u64`, I will add testing div as a separate PR.

56e4e53357 hashes: ci: Remove --all (Tobin C. Harding)
Pull request description:
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!

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?

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.

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.

This fixes several API bugs:
* 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

This was not caught by tests because the optimization is only active for

In order to get better test coverage we should not enable the secp26k1
feature "rand-std" in dev-dependencies but instead feature gate tests
that depend on this feature.
Currently we enable "secp256k1/rand-std" in the "rand" feature, this is
incorrect because it means "rand" implies "std" which it does not.
Add a "rand-std" feature that turns on "seck256k1/rand-std" and make the
"rand" feature turn on "seck256k1/rand".

This is useful when one already has bytes allocated in a vec that can be
reused.
The change also documents that the mirror method `into_bytes()` doesn't
allocate.
`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.

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#522Closes#949
