7c3b198127 Add a simple `Copy`-able `ArrayVec` (Martin Habovstiak)
f17c0402b7 Add tools that help with making code `const` (Martin Habovstiak)
Pull request description:
While we decided to use `arrayvec::ArrayVec`, unfortunately it currently isn't `Copy` even if `T` is because of unfortunate interactions with the `Drop` trait. So this adds a super-simple custom version that is `Copy` and may be extended if we need to or replaced with `arrayvec` if they start supporting `Copy`.

We can have a standard set of derives to make it easier for new devs to
work out what to use and also to help us move towards a uniform set in
preparation for crate stabilization. Mention the new `ordered` crate.
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.
The `arrayvec::ArrayVec` type is not `Copy` which is not nice and we
would like to have a `Copy` type in our crates. While the PR to add
support to the `arrayvec` crate is not merged we implement our own
simplified version.
This one acts mostly as a dumb storage - it has just a few methods and
traits. The new ones can be added as needed later.
There are various challenges when making code `const`: making it
conditional, awkward copying of slices... This change adds tools that
help dealing with these challenges.
a92d49fe33 Implement `CompressedPublicKey` (Martin Habovstiak)
Pull request description:
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`.

43b1ed1b86 Fully encapsulate bitcoinconsensus (Tobin C. Harding)
Pull request description:
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.
### Please note that with this applied:
- The `bitcoinconsenus` crate is no longer exported at the crate root
- No `bitcoinconsensus` types appear in our public API

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.

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.
