38005f6aa7 Use Target for pow_limit (Tobin C. Harding)
Pull request description:
The `Params::pow_limit` field is currently a `Work` type, this is incorrect. The proof of work limit is the highest _target_ not the lowest work (even though these have a relationship).
Note that we use the highest _attainable_ target, this differs from Bitcoin Core and the reasoning is already documented in the code.
Add new consts and document where they came from as well as how they differ to Core.
Use the new consts in the various network specific `Params` types.

Upgrade the `secp256k1` dependency to the newly released `v0.28.0`.
FTR this includes two simple changes:
- Use `Message::from_digest_slice` instead of `Message::from_slice`.
- Use `secp256k1::Keypair` instead of `secp256k1::KeyPair`.
But to stay in line with the keypair change we deprecate and rename the tweaked alias.

incorrect. The proof of work limit is the highest _target_ not the

We have a new API function available with recent version of `secp256k1`
to create a `Message` directly from a sighash byte array.
Use `Message::from_digest(sighash.to_byte_array())` to construct
messages ready to sign.

3e6021bbc6 ci: fuzz test YAML toolchain future-proof (Einherjar)
Pull request description:
To avoid YAML automatic parsing of inputs as floats, e.g. [`1.60` being parsed as `1.6`](https://github.com/rust-bitcoin/rust-bitcoin/pull/2109#issuecomment-1751392327), it is best to future-proof the `toolchain` input in CI fuzz testing as a string.

685e5101ce Add wasm dev-deps using CI script (Tobin C. Harding)
Pull request description:
We only test WASM in CI using a stable toolchain however because we have a target specific dev-dependencies section the wasm deps get pulled in during MSRV builds - this breaks the MSRV build.
Instead of including WASM dev-dependencies in the manifest we can dynamically modify the manifest when running the WASM tests. We do this already to add the `crate-type` section so this is not really that surprising to see in the CI script.
Doing so allows us to stop pinning the transitive `syn` dependency also which is included in the dependency graph because of `wasm-bingen-test`.

Pull request description:
PR aims to achieve two things:
- Make error code brain dead easy to read
- Get error code closer to being ready for v1.0
The first 8 patches are pretty basic, and are broken up into really small changes. The last patch is much bigger, it has a long git log to explain it but reviewing should not take too much brain power.
This PR does not introduce anything new, it just applies what we have been doing recently with errors. Before v1.0.0 others will likely want to re go over all the error types. As such I believe this PR can be merged under the one ack carve-out.
### TODOs (future PRs)
We have a few errors that still need splitting up:
- Split up `merkle_tree::block::MerkleBlockError`
- Split up `psbt::error::Error`
- Split up `IncompleteBuilderError`
Also, all error From's should probably have `#[inline]`, I noticed late in the process and did not have the heart to visit every error again.

We only test WASM in CI using a stable toolchain however because we have
a target specific dev-dependencies section the wasm deps get pulled in
during MSRV builds - this breaks the MSRV build.
Instead of including WASM dev-dependencies in the manifest we can
dynamically modify the manifest when running the WASM tests. We do this
already to add the `crate-type` section so this is not really that
surprising to see in the CI script.
Doing so allows us to stop pinning the transitive `syn` dependency also
which is included in the dependency graph because of `wasm-bingen-test`.
On our way to v1.0.0 we are defining a standard for our error types,
this includes:
- Uses the following derives (unless not possible, usually because of `io::Error`)
`#[derive(Debug, Clone, PartialEq, Eq)]`
- Has `non_exhaustive` unless we really know we can commit to not adding
anything.
Furthermore, we are trying to make the codebase easy to read. Error code
is write-once-read-many (well it should be) so if we make all the error
code super uniform the users can flick to an error and quickly see what
it includes. In an effort to achieve this I have made up a style and
over recent times have change much of the error code to that new style,
this PR audits _all_ error types in the code base and enforces the
style, specifically:
- Is layed out: definition, [impl block], Display impl, error::Error impl, From impls
- `error::Error` impl matches on enum even if it returns `None` for all variants
- Display/Error impls import enum variants locally
- match uses *self and `ref e`
- error::Error variants that return `Some` come first, `None` after
Re: non_exhaustive
To make dev and review easier I have added `non_exhaustive` to _every_
error type. We can then remove it error by error as we see fit. This is
because it takes a bit of thinking to do and review where as this patch
should not take much brain power to review.
In a further effort to make the code brain-dead easy to read; use an
explicit implementation of `std::error::Error` that returns `None`
instead of relying on the default trait implementation.
We would like the codebase to be optimized for readability not ease of
development, as such code that is write-once-read-many should not use
macros.
Currently we use the `impl_std_error` macro to implement
`std::error::Error` for struct error types. This makes the code harder
to read at a glance because one has to think what the macro does.
Remove the `impl_std_error` macro and write the code explicitly.

3b60ad5567 example: Modify `taproot-psbt.rs` to make the use of prevouts clearer. (S. Santos)
Pull request description:
The `taroot-psbt.rs` example uses only one input, and therefore the current code may not make it clear that the number of prevout items must correspond to the number of transaction inputs, since the prevout slice is built within a loop.
This PR aims to make this clear to any user who wants to reuse the logic from the example code.

dac627cc09 Feature: Psbt fee checks (junderw)
Pull request description:
Closes#2061
These new methods on Psbt will add checks for high fees by default. The threshold for "high fees" is currently set to 25000 sat/vbyte, which is about 20x higher than the highest next block fees seen on the "Mempool" website.
The primary goal of this change is to prevent users of the library from accidentally sending absurd amounts of fees.
(ie. Recently in September 2023 there was a transaction that sent an absurd amount of fees and made news in the Bitcoin world. Luckily the mining pool gave it back, but some might not be so lucky.)
There are variants of the method that allow for users to set their own "absurd" threshold using a `FeeRate` value. And there is a method that performs no checks, and the method name is alarming enough to draw attention in a review, so at least developers will be aware of the concept.

c34c709681 CI: add an automated github releases on new tags (Einherjar)
Pull request description:
Creates a `gh-release.yml` that runs on every new tag using the [`ncipollo/release-action`](https://github.com/ncipollo/release-action), which is one of the recommended actions after [GitHub's official `actions/create-release`](https://github.com/actions/create-release) was archived.
The idea is to just have a release with the source code, no binary (although if wanted I can add that as well).
A little bit of context: tcharding told me yesterday at TABConf that he copied manually all commits titles to the release notes somewhere (I think in crates.io?).
This is an easy way to do it, just copy from the GitHub release.
Finally, it is also positive to generate Releases from Tags since this increases the exposure of the repo (GitHub is highly social) while also signaling maturity.
Here's an [example](https://github.com/oven-sh/bun/releases/tag/bun-v0.8.1) that I've found in a non-related repo that has the same `generateReleaseNotes: true` as this PR proposes

Pull request description:
Audit and re-write the weight/size API for `Block` and `Transaction`. First two patches are trivial, patch 3 contains justification and explanation for this work, copied here:
```
Recently we introduced a bug in the weight/size code, while
investigating I found that our `Transaction`/`Block` weight/size APIs
were in a total mess because:
- The docs were stale
- The concept of weight (weight units) and size (bytes) were mixed up
I audited all the API functions, read some bips (141, 144) and re-wrote
the API with the following goals:
- Use terminology from the bips
- Use abstractions that mirror the bips where possible
```
Please note, this PR introduces panics if a sciptPubkey overflows the calculation `weight = spk.size() * 4`.

Pull request description:

## Notes
The PR originally added a `push_p2wphk` method, this is now instead a constrcutor `Witness:p2wpkh` (after review discussion below).
- Patch 1 changes `push_bitcoin_signature` to take an `ecdsa::Sigtnture` instead of an `ecdsa::SerializedSignature`
- Patch 2 takes a `secp256k1::PublicKey` removing the need for an error path (discussed below).
