We already explicitly do not support 16 bit machines.
Also, because Rust supports `u182`s one cannot infallibly convert from a
`usize` to a `u64`. This is unergonomic and results in a ton of casts.
We can instead limit our code to running only on machines where `usize`
is less that or equal to 64 bits then the infallible conversion is
possible.
Since 128 bit machines are not a thing yet this does not in reality
introduce any limitations on the library.
Add a "private" trait to the `internals` crate to do infallible
conversion to a `u64` from `usize`.
Implement it for all unsigned integers smaller than `u64` as well so
we have the option to use the trait instead of `u32::from(foo)`.
2169b75bba Use lower case error messages (Jamil Lambert, PhD)
Pull request description:
Error messages should be lower case, except for proper nouns and variable names. These have all been changed.
~~They should also state what went wrong. Some expect error messages were positive, giving the correct behaviour or correct input. These have been changed so that they are now negative, i.e. saying what went wrong.~~
EDIT: After further discussion it was decided not to change the expect messages.

Wildcards have been replaced with what is actually used.
In a couple of cases an additional use statement was added to the test
module to import `DisplayHex` which is only used in test, but
previously imported with the wildcard at the top.
the `blockdata` directory is code organisation thing, all the
types/modules are re-exported from other places. In preparation for, and
to make easier, the `primitives` crate smashing work - remove all
explicit usage of `blockdata`.
Note that the few instances remain as they seem required e.g.,
`pub(in crate::blockdata::script)`
Refactor only, no logic changes.
In BIP0032, m is used as a variable for the root extended key. It is not
meant to be used as a constant prefix when serializing paths.
Update the DerivationPath parser to no longer require the m prefix.
Remove the m prefix from the unit tests and the bip32, ecdsa-psbt,
and taproot-psbt examples.
close#2449
Our decoding code reads bytes in very small chunks. Which is not
efficient when dealing with the OS where the cost of a context switch is
significant. People could already buffer the data but it's easy to
forget it by accident.
This change requires the new `io::BufRead` trait instead of `io::Read`
in all bounds.
Code such as `Transaction::consensus_decode(&mut File::open(foo))` will
break after this is applied, uncovering the inefficiency.
This was originally Kix's work, done before we had the `io` crate.
Changes to `bitcoin` were originally his, any new mistakes are my own.
Changes to `io` are mine.

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.
We have a convention in `rust-bitcoin` to use external crates directly
when importing them not via `crate::foo`.
Update all the import paths for `io` to use this form.
The BIP-32 extended public key and extended private key exist in the
Bitcoin vernacular as xpub and xpriv. We can use these terms with no
loss of clarity.
Rename our current BIP-32 types
- `ExtendedPubKey` to `Xpub`
- `ExtendedPrivKey` to `Xpriv`
This patch is a mechanical search-and-replace, followed by running the
formatter, no other manual changes.
Last release we added a type alias for `Psbt`, now lets just rename the
type and be done with it.
Includes re-export at the crate root because `bitcoin::Psbt` is clear
and obvious.

1b7b08aa5d De/serialize Psbt without consensus traits (DanGould)
Pull request description:
fix https://github.com/rust-bitcoin/rust-bitcoin/issues/934
Instead of using consensus {de,en}code, serialize high-level structures (PartiallySignedTransaciton, Output, Input) borrow the signature from `Serialize`, `Deserialize` traits and implement them on Psbt:
```rs
impl Psbt {
/// Serialize a value as raw data.
fn serialize(&self) -> Vec<u8>;
/// Deserialize a value from raw data.
fn deserialize(bytes: &[u8]) -> Result<Self, encode::Error>;
}
```

This fixes several API bugs:
* Use `TryFrom` instead of `From` for fallible conversions
* Move byte conversion methods from `impl_array_newtype` to
`impl_bytes_newtype`
* Add missing trait impls like `AsRef`, `Borrow`, their mutable versions
and infallible conversions from arrays
