Export the DisplayHex trait from within prelude
We use `internals::hex::display::DisplayHex` in many places, we can
improve ergonomics of the `internals` crate by re-exporting it from the
`prelude` module.

Merge rust-bitcoin/rust-bitcoin#1531: Remove `ToHex`
1b0988833a Remove `ToHex` (Martin Habovstiak)

Pull request description:

  The `ToHex` trait was replaced by either simple `Display`/`LowerHex` where appropriate or `DisplayHex` from `bitcoin_internals` which is faster.

  This change replaces the usages and removes the trait.

Merge rust-bitcoin/rust-bitcoin#1438: Replace `Vec::from_hex` with `hex!`
089a1e452d Replace `Vec::from_hex` with `hex!` (Martin Habovstiak)

Pull request description:

  This makes the code less noisy and is a preparation for changing it to `const`-based literal. Because of the preparation, places that used variables to store the hex string were changed to constants.

  There are still some instances of `Vec::from_hex` left - where they won't be changeable to `const` and where `hex!` is unavailable (integration tests). These may be dealt with later.

  See also #1189

  Note that while the change appears big it's nearly entirely mechanical, so should be pretty easy to review. (But I don't feel it's `trivial`.)

Martin Habovstiak 8d58ee2ca3 Change `#[cfg(docsrs)]` to `#[cfg(doc)]` on `use`
The additional `use` items were added to improve the style of
documentation. Because they were only used for doc they were `cfg`ed.
But because this is independent from being built by `docs.rs` the `cfg`
should've been `doc` not `docsrs`.

IOW `docsrs` means roughly `all(doc, nightly)` and the added items are
unrelated to `nightly`.

Pull request description:

  This PR uncovered incorrect feature gating in `secp256k1`, fixed in https://github.com/rust-bitcoin/rust-secp256k1/pull/519

  Currently we enable "secp256k1/rand-std" in the "rand" feature, this is incorrect because it means "rand" implies "std" which it does not.

  Add a "rand-std" feature that turns on "seck256k1/rand-std" and make the "rand" feature turn on "seck256k1/rand".

  * Move byte conversion methods from `impl_array_newtype` to `impl_bytes_newtype`
  * Add missing trait impls like `AsRef`, `Borrow`, their mutable versions and infallible conversions from arrays

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.

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

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.

  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.

Martin Habovstiak 1a2cf2681d Implement consensus encoding adapter for serde
In some protocols it is preferred to serialize consensus-encodable types
using consensus encoding. E.g. serialize `Transaction` as hex-encoded
string in Json in Bitcoin Core RPC protocol. This change provides
adapter to make this easier.

The adapter allows providing custom byte-to-string encoder for more
exotic cases and provides a hex implementation which should be useful in
majority of the cases.

Should help with #765

My local scripts did not test serde feature on merge commit. While
merging 734, I accidently broke the serde feature on latest master. This
PR fixes it.

Merge rust-bitcoin/rust-bitcoin#724: Serde regression tests
962abcc963 Add serde regression tests (Tobin Harding)

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?

  Fixes #723

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.

In preparation for removing the `util` module move the `base58` module

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()

Tobin C. Harding db5c8fe61c Move the taproot module to crate root
We are trying to flatten the `util` module. The `taproot` module can
live in the crate root. If/when we create a `crypto` module/crate we may
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.

Includes adding rustfmt attributes to skip formatting of macros.

Kani can't really handle string processing, and appears to be unable
to check integer multiplication (for now), but we do several checks
for addition and subtraction, and conversion between signedness,
that Kani can easily prove.

Currently in `util` module we have a bunch of modules that provide

- key

To improve uniformity and ergonomics, do the following re-names while we
are at it:

- EcdsaSigError -> ecdsa::Error
- SchnorrSigError -> schnorr::Error
