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.

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.

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.

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.

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

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.

Reduce the number of lines of code by using a longer column width, 100

df90c50242 Add log2 to Work (Jiri Jakes)
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:
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?

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.
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()
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.
