Currently we derive `impl Debug for PrivateKey` for "std" builds and
manually implement an obfuscated version for "no-std" builds. Since
we enable the `hashes` feature of `rust-secp` this is unnecessary
because secp takes care of obfuscating the secret for us.
We do not need this dependency because we can get the serde derives
directly from `serde`.

Pull request description:
In order to support standard (de)serialization of structs, the
`rust-bitcoin` ecosystem uses the standard `std::io::{Read,Write}`
traits. This works great for environments with `std`, however sadly
the `std::io` module has not yet been added to the `core` crate.
Thus, in `no-std`, the `rust-bitcoin` ecosystem has historically
used the `core2` crate to provide copies of the `std::io` module
without any major dependencies. Sadly, its one dependency,
`memchr`, recently broke our MSRV.
Worse, because we didn't want to take on any excess dependencies
for `std` builds, `rust-bitcoin` has had to have
mutually-exclusive `std` and `no-std` builds. This breaks general
assumptions about how features work in Rust, causing substantial
pain for applications far downstream of `rust-bitcoin` crates.
This is mostly done, I'm still finalizing the `io::Error` commit at the end to drop the `core2` required dep in no-std, but its getting there. Would love further feedback on the approach or code-level review on these first handful of commits.

In order to move towards our own I/O traits in the `rust-bitcoin`
ecosystem, we have to slowly replace our use of the `std` and
`core2` traits.
Here we take the second big step, replacing
`{std,core2}::io::Read` with our own `bitcoin_io::io::Read`. We
provide a blanket impl for our trait for all `std::io::Read`, if
the `std` feature is enabled, allowing users who use their own
streams or `std` streams to call `rust-bitcoin` methods directly.
Since we are no longer relying on the blanket `io::Write` impl for
`&mut io::Write`, we should now ensure that we do not require
`Sized` for our `io::Write` bounds, as its unnecessarily
restrictive and can no longer be worked around by simply adding an
`&mut`.
`std::io::Write` is implemented for all `&mut std::io::Write`. This
makes it easy to have APIs that mix and match owned `Write`s with
mutable references to `Write`s.
However, in the next commit we add our own `Write` trait which we
intend to implement for all `std::io::Write`. Sadly, this is
mutually exclusive with a blanket implementation on our own
`&mut Write`, as that would conflict with an `std::io::Write`
blanket impl.
Thus, in order to use the `Write for all &mut Write` blanket impl
in rust-bitcoin, we'd have to bound all `Write`s by
`std::io::Write`, as we're unable to provide a blanket
`Write for &mut Write` impl.
Here we stop relying on that blanket impl in order to introduce the
new trait in the next commit.
In order to support standard (de)serialization of structs, the
`rust-bitcoin` ecosystem uses the standard `std::io::{Read,Write}`
traits. This works great for environments with `std`, however sadly
the `std::io` module has not yet been added to the `core` crate.
Thus, in `no-std`, the `rust-bitcoin` ecosystem has historically

without any major dependencies. Sadly, its one dependency,
`memchr`, recently broke our MSRV.
Worse, because we didn't want to take on any excess dependencies
for `std` builds, `rust-bitcoin` has had to have
mutually-exclusive `std` and `no-std` builds. This breaks general
assumptions about how features work in Rust, causing substantial
pain for applications far downstream of `rust-bitcoin` crates.
Here, we add a new `bitcoin_io` crate, making it an unconditional
dependency and using its `io` module in the in-repository crates
in place of `std::io` and `core2::io`. As it is not substantial
additional code, the `hashes` io implementations are no longer
feature-gated.
This doesn't actually accomplish anything on its own, only adding
the new crate which still depends on `core2`.

Currently we have functions on `Address` that call through to a public
`Payload` type. The `Payload` type is an implementation detail and
should never have been public. In preparation for modifying the
`AddressInner` and removing `Payload` altogether lets move all the
functionality from `Payload` into `Address` - this is basically just
code moves so it is feasible to review with some confidence.
This is an API breaking change because it makes `Payload` private and
also removes from the pubic `Address` API functions that accept and
return `Payload`. Apart from that the changes can be seen as
refactoring.
The `AddressEncoding` type exists solely to assist us in implementing
`Display` on `Address`, it may have been used in the past by alt-coins
back when we had a more tolerant outlook on supporting them. Nowadays
we explicitly do not support alts.
Not sure what happened here but our release job didn't catch this? We
should have updated this to "since = 0.31.0" before release. Since we
only deprecate for one release lets go ahead and remove this.
The difficulty is a ratio of the max and current targets, since the
max is network specific the difficulty calculation is also network

This lint forces you to write semantically different code that is in most cases inferior, just to save you 5 characters.
The reason why the code is inferior is because it doesn't do error conversion so it would break when either of the two function signatures changes while in the original code using the `?` operator, nothing would break if the inner error can be converted into the outer error.

hex_psbt was added as a macro so that a panic would reveal the line
number of the failing test by expanding the macro at the test location.
However, a stack trace can be used to reveal the test that caused the
failure using RUST_BACKTRACE=1. Furthermore, the track_caller macro is
added to the helper methods which will reveal the line number of the
calling function (the offending test). More detailed information for
debugging has been added to hex_psbt() so that the offending string
will be included in the panic message.
The macro psbt_with_values is used by the psbt test module. Since
there is no pre-processing required, there is no reason to use
metaprogramming here, so this commit moves the logic from a
macro to common function in the test module.

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.
Upgrade the `secp256k1` dependency to the newly released `v0.28.0`.

- Use `Message::from_digest_slice` instead of `Message::from_slice`.
- Use `secp256k1::Keypair` instead of `secp256k1::KeyPair`.

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.

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.
