This was on a different PR originally, pushing it up on its own.

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?

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.

74ff4946e4 locktime: unify serde impls (Andrew Poelstra)
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.

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!
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.

This still has the line
let lock_time = absolute::LockTime::from_height(psbt.unsigned_tx.lock_time.to_consensus_u32() + lock_time_delta).unwrap();
I'm unsure whether this "adding height to a locktime" concept is a
meaningful thing or just the sort of thing that shows up in example
code. Maybe we should have first-class support for it.
Note that the line, as written, depends on the fact that the original
locktime was a small blockheight. A proper function for this would
handle the exceptional case gracefully.

e00dfa9806 impl FromHexStr for structs with single u32 member (connormullett)
Pull request description:
Closes: #1112
- Adds new trait `FromStrHex` with 2 methods: `from_hex_str` and `from_hex_str_no_prefix`
- Impl new trait on each tuple struct with single u32 member. eg `Time(u32)`
As stated in the issue, grep through codebase with `\(u32\)` and `\(pub u32\)` to see all implementations and verify none were missed.
NonStandardSighashType is an error type and should never be constructed from a hex string. Therefore, it has been omitted from this change.
Tests are somewhat redundant, but cover 4 cases each. 2 happy paths, 1 for each function. 1 case for malformed/invalid hex input, and 1 for calling no_prefix without a prefix
