`Sighash` does not need to implement `Encodable` because it is
claimed (I don't know exactly myself) that `Sighash` is never consensus
encode in Bitcoin.
We are currently relying on `Sighash` to implement `Encodable` when
encoding creating the segwit v0 sighash for a single input.
For reference, from BIP143:
If sighash type is SINGLE and the input index is smaller than the
number of outputs, hashOutputs is the double SHA256 of the output
amount with scriptPubKey of the same index as the input;
We can use `write_all` directly to write the hashed bytes and remove the
implementation of `Encodable` from the `Sighash` type.
While we are at it, use `write_all` to write the zero hash also to make
the code more uniform and understandable.

53ee42d7c1 Fix ASAN in CI (Tobin C. Harding)
Pull request description:
When we merged `hashes` into `rust-bitcoin` we ran the test script a couple of times using `./hashes/contrib/test.sh` this causes the `cargo` commands in the CI script to be run from the crate root which is not what we want.
This showed up recently because `cargo test` was getting run in `bitcoin` after building with address/memory sanitazation configured into the build.
While we are at it run `cargo clean` after the last sanitizer build just to future proof the CI script in case we later accidentally re-use the same build with plain old `cargo` (without `-Zbuild-std etc.`).

Currently the docs build commands in `hashes` and `bitcoin` differ, they
should be the same.
Add a command `cargo doc` to improve coverage e.g., recently we botched
the feature guarding but since CI only runs `cargo rustdoc` with custom
compiler conditional set we didn't catch it.
Run docs in CI using nightly and stable toolchains as required.

testing is never done - add more `mutate` attributes and add unit tests
to ensure all mutants are killed.
Of note, the `from_compact` and `to_compact_lossy` functions are not
done, doing so results in a bunch of surviving mutants.
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`.

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.

```
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.
