8e428562cb Implemented unsized `Script` (Martin Habovstiak)
Pull request description:
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.
This is a more idiomatic alternative to #884 with two unavoidable lines of `unsafe` copied from `std`.

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.

Currently we are using the `--all` flag in `cargo` commands in the
`hashes` CI script. This flag (the deprecated version of `--workspace`)
causes cargo to run the command for the whole workspace, this is not
what we want because we run test individually for each crate using a ci
script per crate.
The effect of this patch is to reduce re-runs of tests i.e., reduce
machine usage during CI runs with no reduction of coverage - PROFIT!
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.

Recently we (tcharding) do some mechanical improvements to the rustdocs
in the `blockdata` module without considering the content. On review a
bunch of improvements were suggested.
Improve the content of various rustdoc comments in the `blockdata`
module.
Suggested content came from reviewers, all mistakes are my own :)
Reduce the number of lines of code by using a longer column width, 100
as is more-or-less standard in this repo.
This patch only changes column width (line length), no other changes.

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.

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.
