Pull request description:

  #1337 was split out of this in an attempt to help review, I think we can merge this one though now it has some traction.

  We would like to bring the `bitcoin_hashes` crate into the `rust-bitcoin` repository. https://github.com/rust-bitcoin/rust-bitcoin/issues/550#issuecomment-1248071843

  Import `bitcoin_hashes` crate into `hashes`.

  Commit hash that was tip of `bitcoin_hashes` at time of import:

       commit 2a78c250f78d391599040223870a4d1d6f6f5482

  Please note the commit history of `bitcoin_hashes` is only preserved on the soon-to-be-archived `bitcoin_hashes` repository.

    ACK 9674bf29fe. Did my best to review the CI code, it looks good, and seems like we are testing everything when we add "hashes" to the root level `./contrib/tests.sh`. I would like other reviewers to confirm the same.

Make `Error` more ergonomic to use by doing:

- Move the `util::Error` to `crate::error::Error`
- Re-export it from the crate root since it is our most general error
- Re-export and deprecated it from `util`

Pull request description:

  Re-done after review comments below. This is now PR 1 in the `merkle_tree::block` series :)

  Move the `merkleblock` module into the `merkle_tree` module in a submodule called `block`. In order to do the minimum amount of changes in this patch DO NOT rename types to improved naming and reduce stutter.

  Note:

  - block module is private
  - the three types are re-exported from `merkle_block`
  - the `MerkleBlock` re-export from the crate root is left in place.

Tobin C. Harding b9643bf3e9 Import bitcoin_hashes crate into hashes
We would like to bring the `bitcoin_hashes` crate into the
`rust-bitcoin` repository.

Import `bitcoin_hashes` into `rust-bitocin/hashes`, doing so looses all
the commit history from the original crate but if we archive the
original repository then the history will be preserved. We maintain the
same version number obviously and in the changelog we note the change of
repository.

Commit hash that was tip of `bitcoin_hashes` at time of import:

 commit 54c16249e06cc6b7870c7fc07d90f489d82647c7

Includes making `embedded` and `fuzzing` per-crate i.e., move them into
`bitcoin` as hashes includes these also.

NOTE: Does _not_ enable fuzzing for `hashes` in CI.

Notes on CI:

Attempts to merge in the github actions from the hashes crate however reduces
coverage by not running hashes tests for beta toolchain. Some additional
work could be done to improve the CI to increase efficiency without
reducing coverage. Leaving for another day.

3c0d5aed73 Add get_tapscript to Witness (junderw)
4226d60205 Add Index<usize> and nth(index) to Witness (junderw)

Pull request description:

  Ref: https://github.com/rust-bitcoin/rust-bitcoin/pull/672#issuecomment-980636502

  [Add Index<usize> and nth(index) to Witness](4226d60205)
  [4226d60](4226d60205)
  Arbitrary indexing into Witness fixes the API of last and second_to_last to be more flexible.
  This patch started off as an addition of third_to_last, but ended up evolving
  into arbitrary indexing to allow for future use cases.

  A list of the indices of the start byte for each witness element is stored as an ordered
  contiguous group of u32s represented as 4 bytes each in the Vec<u8> contents.
  The bytes are stored using to_ne_bytes for performance reasons. A helper function is added
  to the tests to allow for easier contruction of the contents Vec in test vectors. u32 was
  chosen because 22 bits are needed to store 4,000,000 which is the maximum weight limit for
  a block. This might need to be reworked in the event of consensus limits increasing, but
  u32 can hold 1000x the current limit, so it should be fine for the forseeable future.

  The push and consensus_deserialize functions utilize rotate_left and rotate_right to move
  the indices to the end of the new allocation. Depending on the size of the data, this
  might be more of a performance hit than just allocating a new temporary Vec to store the
  indices and append them after parsing is completed. However, for a majority of cases
  rotating the indices should be faster. Suggestions to use VecDeque instead of Vec for
  contents necessitate other considerations, since it is not a public facing change,
  those optimizations can be dealt with in future patches.

  The Index<usize> trait is implemented using the new nth method with expect.

  The Iter struct is reworked to make use of the new data representation. This new data
  structure makes it trivial to implement DoubleEndedIterator and other such traits, but
  I have decided to leave this as out of scope for this patch.

  ---

  [Add get_tapscript to Witness](a7501d9599)
  [a7501d9](a7501d9599)
  This new method will check the last witness element to see if it starts with 0x50, and
  depending on the result it will return the second to last or third to last witness
  element according to BIP341.

  In its current state, Witness can not know what type of script it is fulfilling,
  so it is up to the caller to verify if the previous output is a taproot output or not.

  ---

  Edit: This is the previous PR body:

  > In a taproot script payment with annex, quick access to the 3rd to last element (which is the actual script in this case) is convenient.
  >
  > This feels like kicking the can down the road again, but I think it's a nice to have method.
  >
  > RCasatta dr-orlovsky were discussing this issue. I would like to ask if they have any thoughts on the addition of this.

Merge rust-bitcoin/rust-bitcoin#1349: Remove `into_bytes` from `impl_array_newtype`
8c4fa5ec3d Remove into_bytes from impl_array_newtype (Tobin C. Harding)

Pull request description:

  All the types that we define with `impl_array_newtype` are `Copy` so the correct conversion method to get the underlying byte array is `to_bytes`. We currently provide `into_bytes` as well as `to_bytes`, with one of them calling `clone` - this is unnecessary and against convention.

  Remove `into_bytes` and for `to_bytes` just return the inner field. Add code comment to remind devs of correct usage of the macro in regards to deriving `Copy` and `Clone`.

capital letters.

Tobin C. Harding 832169eb8d Add to/from_consensus methods to Version type
The `Version` type uses a signed 32 bit integer inner type but we bit
twiddle as if it was a `u32`. We recently made the inner type private to
hide the data type because of this oddness.

Add methods `from_consensus` and `to_consensus` to facilitate any
possible thing users may want to do with a consensus version value.

Tobin C. Harding 24984f095f Make block::Version inner value private
The Bitcoin block version is a signed integer for historical reasons,
but we bit twiddle it like an unsigned integer and during consensus
encode/decode we cast the signed value to an unsigned value.

In order to hide this confusion, make the inner value private and add a
couple of constants for v1 and v2 block versions.

Tobin C. Harding 7e146ede96 Make types in block module more terse
Currently the types in the block module have longer names than
necessary, "header" and "version" identifiers contain the word "block",
this is unnecessary because we can write `block::Header` instead of
`BlockHeader` when context is required. This allows us to use the naked
type `Header` inside the `block` module with no loss of clarity.

We are stuck with `BlockHash` because the type is defined along with all
the other hash types in `hash_types`, leave it as is for now but
re-export it from the `block` module to assist in putting types that are
used together in scope in the same place, making import statements more
ergonomic.

Tobin C. Harding 2157e69857 Document the `all` module
The `all` module enables usage of a wildcard import statement without
muddying the scope with any other types defined in `opcodes`, in other
words if one wants to use the `All` type `opcodes::All` is the most
clear way to use it, however usage of naked `OP_FOO` types is perfectly
clear.

Add documentation stating that we guarantee to never put anything else
in the `all` module so folks are confident using a wildcard import will
not bring any rubbish into scope.

Expected usage in downstream applications that need types in `opcodes`
as well as the opcodes:

```
        use bitcoin::opcodes::all::*;
        use bitcoin::opcodes;
```

Also, we do no implement `Ord` or `PartialOrd`, document this including
HTML tags hiding an example bug from Bitcoin Core that shows why not.

Merge rust-bitcoin/rust-bitcoin#1344: Fix `no_std` when `bitcoinconsensus` is enabled
b6f9e47dba Fix `no_std` when `bitcoinconsensus` is enabled (Martin Habovstiak)

Pull request description:

  `default-features = false` was missing previously but blindly adding it would lead to subtle risk of breaking when a crate not needing `std` depends on `bitcoinconsensus` and simultaneously another crate not needing `bitcoinconsensus` depends on `std` and another crate depends on them both.

  This change fixes it by introducing `bitcoinconsensus-std` feature flag and provides a fallback if the flag is off. Unfortunately the fallback has to use a bit of reasonable `unsafe` due to limitations of upcasting.

  The only safe alternatives are not do it and provide worse experience for crates that are affected by the problem above or break the API, which couldn't be backported and would be more annoying to use.

  Closes #1343

  This is considered PoC PR as I realized the possibility of the hack (and necessity of `unsafe`) at the last moment. Things like tests and modifying CONTRIBUTING to change the stance on `unsafe` will be added if `unsafe` is ACKed.

Pull request description:

  Done as part of flattening `util`.

  The `util::hash` module only provides two functions, both to calculate the merkle root of a list of hashes.

  1. Rename `util::hash` -> `crate::merkle_root`
  2. Change function names to `calculate[_inline]` so usage becomes `merkle_root::calculate`

  Done as two separate patches so we can bikeshed the names, can squash if needed.
