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:
In order to create the witness to spend p2wpkh output one must create a `Witness` that includes the signature and the pubkey, we should have a function for this.
## 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).

The `Witness::push_bitcoin_signature` method is old and a bit stale.
Bitcoin has taproot signatures now so the name is stale, also we have
the `crate::ecdsa::Signature` type that holds the secp sig and the hash
type so we can use that instead of having two separate parameters.
Add a new, up to date, `Witness::push_ecdsa_signature` function and
deprecate the `push_bitcoin_signature` one.
There is no logical default for the transaction version number, there is
only pre-bip68 (v1) and post-bip68 (v2). Uses should specify the version
they want not rely on us making the choice.
(I originally added this impl to support testing, this was in hindsight
the wrong thing to do, props to Sanket for noticing.)
One of our stated aims is to make it possible to learn bitcoin by using
our library. To help with this aim add to private consts for the segwit
transaction marker and flag serialization fields.
158ba26a8a Feature: Count sigops for Transaction (junderw)
Pull request description:
I copied over the sigop counting logic from Bitcoin Core, but I made a few adjustments.
1. I removed 2 consensus flags that checked for P2SH and SegWit activation. This code assumes both are activated. If we were to include that, what would be a good way to go about it? (ie. If I run this method on a transaction from the 1000th block and it just so happened to have a P2SH-like input, Bitcoin Core wouldn't accidentally count those sigops because the consensus flag will stop them from running the P2SH logic. Same goes for SegWit)
3. Since there's no guarantee that we have an index from which we can get the prevout scripts, I made it into a generic closure that looks up the prevout script for us. If the caller doesn't provide it, We can only count sigops directly in the scriptSig and scriptPubkey (no P2SH or SegWit).
## TODO
- [x] Write tests for transaction sigop counting
~~Edit: The test changes are just to get the 1.48 tests passing. I'll remove them and replace them with whatever solution that is agreed upon in another PR etc.~~
Edit 2: This is the code I used as a guide:
8105bce5b3/src/consensus/tx_verify.cpp (L147-L166)
Edit 3: I found a subtle bug in the implementation of `count_sigops` (https://github.com/rust-bitcoin/rust-bitcoin/pull/2073#issuecomment-1722403687)

f17bb0d18f Remove unnecessary reference (Tobin C. Harding)
Pull request description:
`T` is a generic that implements`AsRef<PushBytes>`, it should not be a reference. This is inline with other usages of `AsRef<PushBytes>` for example in `Builder::push_slice`.
Found while working on #2003
