Martin Habovstiak 8e428562cb Implemented unsized `Script`
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.

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.

  Closes #1455

Merge rust-bitcoin/rust-bitcoin#1450: hashes: Do not implement `Deref`
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.

examples: clean up taproot PSBT example locktime handling
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.

Merge rust-bitcoin/rust-bitcoin#1400: Add trait `FromStrHex` for tuple structs with single `u32` member
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

connormullett e00dfa9806 impl FromHexStr for structs with single u32 member
Adds new module `string` to be later converted to its own
crate. The module currently contains the FromHexStr trait and an error
type to be used for implementing hex parsing on types. This change
also adds implementations of FromHexStr for types with a single u32
member such as `Sequence(pub u32)`. All structs that match the
following regex have been given this implementation
`\(u32\)` and `\(pub u32\)`. All implementations have associated
unit tests matching all possible cases. NonStandardSighashType has
been ommitted from this change as it is an error and should not be
constructed using the methods added in this change.

Adds parse::hex_u32 for future use to be made generic to allow
different sizes of integers to be parsed from hex strings.

The error type FromHexError implements required traits such as
Display and std::error::Error

Merge rust-bitcoin/rust-bitcoin#1428: Adds Network::from_core_arg and links it to Network::from_str
d7006ef80d Adds roundtrip tests for Network::from_core_arg (Sergi Delgado Segura)
bd1eb29f61 Adds Network::to_core_arg (Sergi Delgado Segura)

Pull request description:

  Comming from https://github.com/rust-bitcoin/rust-bitcoincore-rpc/pull/247

  `Network::from_str` only considers `rust-bitcoin` string as possible inputs to create a `Network` instance. This PR adds a new method to `Network`, `from_core_arg`, which is complementary to the existing `Network::to_core_arg`. This method allows the conversion between `bitcoind -network` string and `Network` variants.

  This also links `Network::from_str` to `Network::from_core_arg` so the default case on the former calls the latter, and an error is only returned if none of the cases match.

Pull request description:

  Adds method `Work::log2()` providing value equivalent to Bitcoin Core's `log2_work` in its logs. Fixes #1326.

  Questions:

  - The original issue (#1326) also suggests to add log2 to Target but it does not seem to be meaningful, does it? Bitcoin Core, to which the issue refers, also displays only log2 of work.
  - Although work should not be 0, the type allows it. In this case, log2 would return -inf. I think we could leave it like that but if there are suggestions to deal with it in a different way, please let me know.

Pull request description:

  `no_run` is not needed since we already mark this up as `bash` which rustc doesn't run when running examples.

  While the keyword `bash` is not currently supported it may well be in the future and since only the `rust` keyword causes code to run any other string is effectively a wildcard, `no_run` is therefore meaningful only as a convention. Lets keep `bash` in case support is added later on.

Pull request description:

  Attempts to add regression tests for _all_ types defined in `rust-bitcoin` that implement `Serialize`/`Deserialize`.

  - Add a `tests` directory and implement regression tests in there
  - Use files for input hex and output bincode to reduce source file clutter
  - Copy test block and `include_bytes!` usage from RCasatta's [PR](https://github.com/rust-bitcoin/rust-bitcoin/pull/750)
  - Uses Kixunil's macro suggested below
  - Adds a single regression test to `util/taproot.rs` for private types

  ## Note to reviewers
  - Uses JSON for opcodes in a separate file (`tests/regression_opcodes.rs`), for all other tests uses bincode.
  - Bypasses the order issue for maps by only serializing maps with a single element - is this correct?

Tobin C. Harding 13d94cbc47 Remove no_run
`no_run` is not needed since we already mark this up as `bash` which
rustc doesn't run when running examples.

While the keyword `bash` is not currently supported it may well be in
the future and since only the `rust` keyword causes code to run any
other string is effectively a wildcard, `no_run` is therefore meaningful
only as a convention. Lets keep `bash` in case support is added later on.

Tobin C. Harding 2780e6cdaa Move base58 module to crate root
In preparation for removing the `util` module move the `base58` module
to the crate root. This is likely not the final resting place for this
module but it is a step in the right direction.

Includes addition of rustfmt attribute to skip formatting the digits
array. No other changes to the `base58` module.

connormullett 25f781bef3 Implement p2pk_public_key + tests
For some applications, such as block explorers, it's useful to be able
to obtain the public key used in case of P2PK. This is considered
general enough for addition into bitcoin library,
so this change adds it.

The public key is returned only when it's valid and the script is P2PK.
To avoid duplicating the logic checking whether a script is P2PK the
logic is moved to a new p2pk_pubkey_bytes() method which returns raw
bytes and is then called from both is_p2pk() and p2pk_public_key()

wish to pull some stuff out of this module but for now moving it gets us
closer to removing `util` without making the directory structure any
worse.

Can one reviewer please verify the last patch consists only of `rustfmt` changes by running the command on their branch. Thanks

  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.

  This patch purposefully does the minimum amount of changes because there a whole bunch of improvements to the old "merkleblock" module that are coming next in a separate PR.

Tobin C. Harding 613107298d Move merkleblock into merkle_tree
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`

This patch purposefully does the minimum amount of changes because there
a whole bunch of improvements to the old "merkleblock" module that are
coming next.

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.

The Bitcoin block version is a signed integer for historical reasons,

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.
