a8d50a5541 Remove Push enum (Tobin C. Harding)
Pull request description:
The `Push` enum is only ever used to get access to one of its variants. Since it is a private type we can remove it entirely and just return `PushBytes` from the `last_pushdata` function.
Needs careful review but I believe the function name is still correctly descriptive.

The `as_unchecked` method is never dangerous to call because an
`Address<UncheckedNetwork>` provides a subset of functionality that is
always ok to use. It is only dangerous to go the other way unchecked to
checked.
This lint triggers on `fn input_len(&self) -> usize { match *self {} }`
where Self is an infallible type, claiming that the dereference of self
is UB. Maybe it would be, if this were possible. But it's not, and this
is literally the only point of using infallible types, so this lint is
always wrong.
Enabled in rustc 1.76 as warn by default.
This method is not really that useful because it checked an arbitrary
condition. There already exists `OP_RETURN` semantics and the method
didn't cover all possible ways the script may be invalid.
This deprecates the method and documents why.

BIP-32 only differentiates between mainnet and some testnet when
encoding and decoding xpubs and xprivs. As such we can use the new
`NetworkKind` type instead of `Network` throughout the `bip32` module.
We only use the network to serialize and deserialize from WIF.
For this we only really need network kind since WIF only differentiates
between mainnet and non-mainnet.
Add a new type `NetworkKind` the describes the kind of network we are
on, ether mainnet or one of the test nets (testnet, regtest, signet).
Do not use the type yet.

P2WPKH requires keys to be compressed which introduces error handling even in cases when it's statically known that a key is compressed. To avoid it, this change introduces `CompressedPublicKey` which is similar to `PublicKey` except it's statically known to be compressed.

The `bitcoinconsensus` crate is not fully under our control because it
exposes code from Core, so we cannot guarantee its stability across
versions. To make our semver compliance easier we can fully encapsulate
the `bitcoinconsensus` crate so it does not appear in our public API.
However, it is useful to have the crate itself exported, here we add an
"unstable" feature and only publicly export the `bitcoinconsensus` crate
if the "unstable" feature is enabled.
P2WPKH requires keys to be compressed which introduces error handling
even in cases when it's statically known that a key is compressed. To
avoid it, this change introduces `CompressedPublicKey` which is similar
to `PublicKey` except it's statically known to be compressed.
This also changes relevant code to use `CompressedPublicKey` instead of
`PublicKey`.
There is no advantage in having `io::Read` as opposed to `Read` and
importing the trait. It is surprising that we do so.
Remove `io::` path from `io::Read` and `io::Write`. Some docs keep the
path, leave them as is. Add import `use io::{Read, Write}`.
Refactor only, no logic changes.
When we use the `fmt::Write` trait it is just to call its methods, we
can therefore, without any change to the logic, use `as _` when
importing the trait. This prevents naming conflicts.
Done in preparation for importing the `io::Write` trait.
Generic types can be single letters, and a writer is conventionally, in
this codebase at least, called `W`.
Use `W` instead of `Write` with no loss of clarity.

Pull request description:
An `AddressInner` struct (contains `Network` field) is created when parsing address strings however address strings do not map 1:1 to `Network` because signet and testnet use the same bech32 prefix "tb".
We can fix this by inlining the `Payload` variants into `AddressInner` and adding prefix enums for legacy addresses and an `Hrp` for bech32 addresses.

1b23220d10 Fix: TxOut::minimal_non_dust and Script::dust_value (Jonathan Underwood)
Pull request description:
Fixes#2192
TxOut::minimal_non_dust has 3 problems.
1. There is an invisible dependency on Bitcoin Core's default minrelaytxfee value. It has been made explicit.
2. There is an off by one error. The dust limit comparison uses < and therefore `+ 1` was not needed. It has been fixed.
3. It was not returning 0 amount for OP_RETURN outputs.
Script::dust_value has 2 problems.
1. The dust amount depends on minrelaytxfee which is configurable in Bitcoin Core. This method was not configurable.
2. The division operation was done before multiplying the byte amount, which can cause small differences when using uncommon scripts and minrelaytxfee values.

Since we do `& 1`, only 0 and 1 are possible values, so the error return
there can never happen. I made this explicit by manually setting the
parity.
This is a rebase of Steven's change with a rewrite of `match` to not
panic.
Since the iterator created by `IntoIterator` should be called `IntoIter`
we move the whole `TaprootMerkleBranch` to its own module which contains
the type to avoid confusion. This has an additional benefit of reducing
the scope where the invariant could be broken. This already uncovered
that our internal code was abusing access to the private field (although
the code was correct).
To implement the iterator we simply delegate to `vec::IntoIter`,
including overriding the default method which are likely to be
implemented by `Vec` more optimally. We avoid exposing `vec::IntoIter`
directly since we may want to change the representation (e.g. to
`ArrayVec`).
The type is naturally a collection of hashes so make it behave that way
by implementing `Deref`, `AsRef`, `Borrow` and their mutable versions as
well as `IntoIterator` for its reference. `IntoIterator` for itself is
not yet implemented because it's a bit more complicated.
While `clippy` now allows `TBD` to be used in `since` parameter of
`deprecated` attribute it is only available in the newest, nightly,
version. Switch `clippy` version to nightly to enable the `TBD` value.
