9bb75703a1 Header change from arguments to parameters (jamil.lambert)
Pull request description:
In a few cases a function header documents the parameters of the following function under the heading "Arguments", this has been changed to "Parameters".
Since the description is at the level of the function definition and not where it is being called parameters seems the more accurate term.

Pull request description:
https://github.com/rust-lang/rust/issues/124800 has been fixed and we can update our nightly version by whitelisting all cfgs that are used.
There was one place where we had an old `cfg(feature = "no-std")` despite having removed the feature. By removing that cfg check we re-enabled a previously disabled test.

In a few cases a function header documents the parameters of the following function under the heading"Arguments", this has been changed to "Parameters"
The formatter lines up comments if they are on consecutive lines even
if the second is supposed to be at the start of the collum and the
first is after code. Putting a line of whitespace between the two
lines stops this from happening.
Add whitespace to stop the formatter doing silly changes.
Whitespace only.
Clean up the test imports in the `p2p` module:
- Use `use super::*` as is conventional.
- Use `sha256d::Hash` as is conventional.
Refactor, no logic changes.

Currently we use the `Hash` trait in a bunch of places to call
`all_zeros`. We are attempting to improve the `hashes` API and this
usage is both unnecessary and also hindering that effort.
Use the concrete type (e.g. `BlockHash`) instead of calling through the
trait method.
Refactor only, no logic changes.
47dc4a3180 feat(pow): add difficulty adjustment calculation (Rob N)
Pull request description:
Hi, I hit a roadblock with the current `pow` API. As far as I can tell, the only workaround to calculate the next work required similar to `bitcoin/src/pow.cpp` is to use a general big integer library, convert the `Target` to bytes, do the math, and convert back to `Target` from bytes. I have also been working with [Floresta](780ea8d0b0) and their [solution](780ea8d0b0/crates/floresta-chain/src/pruned_utreexo/consensus.rs (L187)) was to fork off and exposed the `U256` struct publicly on their branch. I think these home brewed difficulty adjustment solutions will continually pop up, so I created a `from_next_work_required` method to return a `Target`. My work veers significantly from #2180, as I only provided a single method to do so, without further guidance on when exactly this retarget occurs.
I am happy to add tests once I get further direction from maintainers if this as a likelihood of being accepted or not. Thanks.

From the final patch:
Displaying backward is an anomaly of Bitcoin Core's early days and the
double SHA256 hash type. We should not let this unfortunate beast leak
out into other places.
Default to displaying forward when creating a new tagged hash and remove
all the explicit attributes from `bitcoin` that just clutter the code.
This is an API break and may quietly break some users downstream - eventually we should stop doing that sort of thing.

Currently we require indexing trait bounds as well as `Borrow` on the
`Hash` trait. We also already implement `AsRef`.
It was observed that `Borrow<[u8]>` does not best describe what we want
from the `Hash` trait implementor but rather `AsRef<[u8]>` does.
Remove all the inexing trait bounds. Remove the `borrow::Borrow<[u8]>`
trait bound. Add a `convert::AsRef<[u8]>` trait bound.
This leaves the `Borrow<[u8]>` implementation for hashes created with
`hash_newtype`, I'm not sure if this should be removed or not.

26b9782d8b CI: Re-write run_task.sh (Tobin C. Harding)
Pull request description:
Recently we re-wrote CI to increase VM level parallelism, in hindsite this has proved to be not that great because:
- It resulted in approx 180 jobs
- We are on free tier so only get 20 jobs (VMs) at a time so its slow to run
- The UI is annoying to dig through the long job list to find failures
Have another go at organising the jobs with the main aim of shortening total run time and making it easier to quickly see fails.
Re-write the `run_task.sh` script, notable moving manifest handling to the workflow. Also don't bother testing with beta toolchain.
### Note on review
The diff is hard to read for `rust.yml`, I tried splitting out a bunch of separate patches but it resulted in the same thing (because there are so many identical lines in the yaml file). I suggest just looking at the yaml file and not the diff.

WASM Note
Removes the `cdylib` and `rlib` from the manifest patching during wasm
build - I do not know the following:
- Why this breaks on this PR but not on other PRs
- Why I can't get wasm test to run locally on master but PRs are passing
- What the `cdylib` and `rlib` were meant to be doing
This is the docs from: https://doc.rust-lang.org/reference/linkage.html
* --crate-type=cdylib, #![crate_type = "cdylib"] - A dynamic system
library will be produced. This is used when compiling a dynamic library
to be loaded from another language. This output type will create *.so
files on Linux, *.dylib files on macOS, and *.dll files on Windows.
* --crate-type=rlib, #![crate_type = "rlib"] - A "Rust library" file
will be produced. This is used as an intermediate artifact and can be
thought of as a "static Rust library". These rlib files, unlike
staticlib files, are interpreted by the compiler in future linkage. This
essentially means that rustc will look for metadata in rlib files like
it looks for metadata in dynamic libraries. This form of output is used
to produce statically linked executables as well as staticlib outputs.
As part of the ongoing effort to improve `hashes`; stop using slicing of
hash types and use `as_byte_array()` to get an array reference instead.
This gives us more flexability to modify the `hashes` module.
If one writes signing data using one of the two
`*_encode_signing_data_to` functions then creating the message to sign
is slightly nuanced and different for each of the functions. For Taproot
one must use a specific tagged hash and for ECDSA one must use a sha256d
hash.
Add documentation that explains the hashing requirements for each
function.
Displaying backward is an anomaly of Bitcoin Core's early days and the
double SHA256 hash type. We should not let this unfortunate beast leak
out into other places.
Default to displaying forward when creating a new tagged hash and remove
all the explicit attributes from `bitcoin` that just clutter the code.

Pull request description:
Recently in #2451 we disallowed bip32 derivation paths with the leading 'm' variable.
There is some confusion as to what exactly the bip specifies however Bitcoin Core RPC call `getaddressinfo` returns a derivation path with a leading "m/". This means we need to be able to parse it irrespective of what the bip says.
Be more liberal in what we accept as a derivation path, including both with and without the leading 'm/'.
Leave the full investigation of the bip to a later date.

The deprecation notice for `is_provably_unspendable` contains "is not
very useful" which is a bit presumptuous to tell to users, it may very
well be useful to them. Use the more helpful text that already exists in
rustdoc on the function.
We only check clippy in CI with --all-features, which usually is the
best way to get maximum coverage. But if you try a couple other feature
combos, especially those related to nostd, you can hit more code.
