bef7c6e687 Use marker type to enforce validation of `Address`'s network (Jiri Jakes)
Pull request description:
Adds marker type `NetworkValidation` to `Address` to help compiler enforce network validation. Inspired by Martin's suggestion. Closes#1460.
Open questions:
1. Compilation fails with serde, which uses `Address:from_str` via macro `serde_string_impl!(Address, "a Bitcoin address");`. I don't think there is much we can do, so unless somebody has a better idea how to combine serde and network validation, I would just demacroed the macro for `Address` and add `unsafe_mark_network_valid` into it.
2. Would someone prefer wrapping the validation types by `mod validation`? As they are now, they live in `address` namespace so I don't think mod is necessary.
3. Almost all methods that used to be on `Address` are now on `Address<NetworkValid>` except one (`address_type`) that needs to be called on both and a few that are only on `Address<NetworkUnchecked>` (mainly `is_valid_for_network`). Some methods (e. g. `to_qr_uri`, `is_standard` and perhaps others) could be, theoretically, called on both valid and unchecked. I think we should encourage validating the network ASAP, so I would leave them on NetworkValid only, but I can move them if others have different opinion.
4. Should `NetworkValid` and `NetworkUnchecked` enums have some trait impls derived? The `PartialEq` was necessary for tests (I think `assert_eq` required it) but I am not sure whether some other would be good to have. The enums are only used as types so I guess it's not necessary, but also I do not fully understand why the `PartialEq` was needed.

Parsing addresses from strings required a subsequent validation of
network of the parsed address. However, this validation was not
enforced by compiler, one had to remember to perform it.
This change adds a marker type to `Address` that will assist the
compiler in enforcing this validation.
f39cd88f5f Use TapNodeHash in NodeInfo (sanket1729)
5ff2635585 Rename TapBranchHash -> TapNodeHash (sanket1729)
Pull request description:
This does not completely fix#1393 but is a simple starter. Unfortunately, we still need hash_new_type for `TapNodeHash` because is exported as the Merkle root in taproot psbt. This requires serialization and display/from_str methods.
This also adds a method 1) `TapNodeHash::from_script` to deal with single leaf case cleanly. As a nice side effect, this removes the ugly uses of `sha256::Hash` that I had used to represent both `TapLeafHash` and `TapBranchHash`
Does not fix
1) Exporting `TapTweakHash`. This requires some changes to macros we use.
2) Safer usage of `TapNodeHash` by not making it `hash_new_type` and having guarded constructors. As mentioned above, this is required for psbts and sharing Merkle roots. Perhaps, we might need a new type while constructing trees that is not `hash_new_type`, and convert it to another type that represents the final Merkle root.
My overall feeling is that this is best addressed with more examples than changing and complicating existing code.
I don't feel strongly about the rename, so can go back if `TapBranchHash` instead of `TapNodeHash`.

15b5af1117 Export sha512::HashEngine fields/function within the crate (Calvin Kim)
Pull request description:
Adds a new file named `sha512_256.rs` that implements the `sha512/256` hash. This was needed as a part of https://github.com/rust-bitcoin/rust-bitcoin/discussions/1318 to drop the `sha2` dependency.
All the actual hashing code is exactly the same as `sha512.rs`, minus the initial constants and the use of `hash_type!` macro. Some unit tests were added from wikipedia (for the "" input) and the rest were from the Go standard library's tests for sha512_256.
Benchmarks on my Ryzen 3600 machine show that it is faster than sha256.
```
test sha256::benches::sha256_10 ... bench: 37 ns/iter (+/- 0) = 270 MB/s
test sha256::benches::sha256_1k ... bench: 3,338 ns/iter (+/- 24) = 306 MB/s
test sha256::benches::sha256_64k ... bench: 213,605 ns/iter (+/- 1,806) = 306 MB/s
test sha512_256::benches::sha512_256_10 ... bench: 27 ns/iter (+/- 1) = 370 MB/s

test sha512_256::benches::sha512_256_64k ... bench: 140,552 ns/iter (+/- 777) = 466 MB/s
```
One caveat is that I could not get hongfuzz to build locally so I couldn't test the fuzz on my machine. I ended up only testing through the CI for the fuzz tests.
I thought adding a completely separate file was the easiest and the most straightforward way of implementing it. I'm very much open to changing the implementation if you guys don't think this is the right direction.

3e520f9094 Use hex from internals rather than hashes (Martin Habovstiak)
Pull request description:
`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.

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.
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 kani verification for `U256::mul_u64`, doing so uncovered a bug in
the current implementation due to overflow.
Re-write the `mul_u64` method.
Props to Elichai for the algorithm.

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.

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).
