Tobin Harding e37652578b Rename PsbtSigHashType -> PsbtSighashType
Our usage of `SigHash` implies that 'sighash' is _two_ words; 'sighash'
is a well known word in the Bitcoin ecosystem it should appear in
identifiers as `Sighash`.

Rename `PsbtSigHashType` to `PsbtSighashType`.

Tobin Harding 71cf00a314 Use less vertical lines
In this library we specifically do not use rustfmt and tend to favour
terse statements that do not use extra lines unnecessarily. In order to
help new devs understand the style modify code that seems to use an
unnecessary number of lines.

None of these changes should reduce the readability of the code.

Tobin Harding 702e8bf82d Refactor consensus_encode
The implementations of `consensus_encode` use an unnecessary number of
lines. Favour more terse code with no loss of clarity.

Tobin Harding bf4f5638e0 Refactor whitespace
Do various whitespace refactorings, of note:

- Use space around equals e.g., 'since = "blah"'
- Put return/break/continue on separate line

Whitespace only, no logic changes.

Separate merge logic out of Map trait
Recently we (*cough* Tobin) made the `Map` trait private and neglected
to add a public API for combining together two PSBTs. Doing so broke the
`psbt` module.

Pull the merge logic out of the `Map` trait and put it in methods on
each individual type (`Input`, `Output`, `PartiallySignedTransaction`).
Doing so allows for simplification of return types since combining
inputs/outputs never errors.

Use the term 'combine' instead of 'merge' since that is the term used in
BIP 174.

Tobin Harding b138428df7 Re-export public map types from root level
We currently have the `map` module private but containing a bunch of
types that are needed in the public API (specifically in a
`PartiallySignedTransaction`).

Re-export the publicly required types to the `psbt` module and then
again at the root level of `rust-bitcoin` as we do for other types.

Tobin Harding ad75d5181f Make Map trait private to psbt module
The `Map` trait has been deemed confusing and not that useful to users
of the library, we still use it internally within the `psbt` module
though so make it visible only in `psbt` and `psbt::map`.

Dr Maxim Orlovsky a6e8f581db PSBT BIP32 keys moved to Secp256k1 from bitcoin ECDSA
Fourth step in implementation of Schnorr key support after #588.

While PSBT BIP174 does not specify whether uncompressed keys are supported in BIP32-related fields, from BIP32 it follows that it is impossible to use uncompressed keys within the extended keys.  This PR fixes this situation and is a companion to BIP174 PR clarifying key serialization: https://github.com/bitcoin/bips/pull/1100

Pull request description:

  This is third step required to introduce Schnorr key support according to #588. This PR starts API-breaking changes and is follow-up to non-API breaking #589, which is already merged.

  PR rationale: BIP32 does not support uncompressed keys and using type with compression flag was a mistake

Riccardo Casatta 2fd0125bfa
Introduce Witness struct mainly to improve ser/de performance while keeping most usability.
Witness struct is in place of the Vec<Vec<u8>> we have before this commit.

from_vec() and to_vec() methods are provided to switch between this type and Vec<Vec<u8>>

Moreover, implementation of Default, Iterator and others allows to have similar behaviour but
using a single Vec prevent many allocations during deserialization which in turns results in
better performance, even 20% better perfomance on recent block.

last() and second_to_last() allows to access respective element without going through costly Vec
transformation

Merge rust-bitcoin/rust-bitcoin#654: Making globals part of PSBT struct. Closes #652
55c627715f Moving globals into PSBT struct (Dr Maxim Orlovsky)

Pull request description:

  I took the most non-invasive approach to reduce diff size. Many parts of the code can be improved in style or further refactored (like some functions are not necessary and can be just moved to be part of other functions), but I'd prefer to do that as a separate PR once this will be merged.

  My approach with this PR:
  1. Remove `Global` struct by moving its fields right into `PartiallySignedTransaction` - but keep the `util/psbt/map/global.rs` file with all its logic
  2. Keep existing `Map for Global` implementation in the same file, but just change it to `Map for PartiallySignedTransaction`
  3. With serialization, convert `Global` deserialization into crate-private function and use it from `PartiallySignedTransaction` deserialization
  4. Refactor the tests and imports as required to get the thing compile and pass tests

  The refactoring will be followed by PR(s) adding support for Taproot

Tobin Harding 3f5caa501f Clean up module level rustdocs
Docs can always do with a bit of love.

Clean up the module level (`//!`) rustdocs for all public modules.

I claim uniform is better than any specific method/style. I tried to fit
in with what ever was either most sane of most prevalent, therefore
attaining uniformity without unnecessary code churn (one exception being
the changes to headings described below).

Notes:

* Headings - use heading as a regular sentence for all modules e.g.,

```
//! Bitcoin network messages.
```

as opposed to
```
//! # Bitcoin Network Messages
```

It was not clear which style to use so I picked a 'random' mature
project and copied their style.

* Added 'This module' in _most_ places as the start of the module
description, however I was not religious about this one.

* Fixed line length if necessary since most of our code seems to follow
short (80 char) line lengths for comments anyways.

* Added periods and fixed obvious (and sometimes not so obvious)
grammatically errors.

* Added a trailing `//!` to every block since this was almost universal
already. I don't really like this one but I'm guessing it is Andrew's
preferred style since its on the copyright notices as well.

Martin Habovstiak 95fb4e01f9 Document cargo features
This documents cargo features in two ways: explictly in text and in code
using `#[doc(cfg(...))]` attribute where possible. Notably, this is
impossible for `serde` derives. The attribute is contitional and only
activated for docs.rs or explicit local builds.

This change also adds `package.metadata.docs.rs` field to `Cargo.toml`
which instructs docs.rs to build with relevant features and with
`docsrs` config activated enabling `#[doc(cfg(...))] attributes.

I also took the opportunity to fix a few missing spaces in nearby code.

Devrandom 4826d0c6cc no_std support
Based on the original work by Justin Moon.

*MSRV unchanged from 1.29.0.*

When `std` is off, `no-std` must be on, and we use the [`alloc`](https://doc.rust-lang.org/alloc/) and core2 crates. The `alloc` crate requires the user define a global allocator.

* Import from `core` and `alloc` instead of `std`
* `alloc` only used if `no-std` is on
* Create `std` feature
* Create `no-std` feature which adds a core2 dependency to polyfill `std::io` features. This is an experimental feature and should be
used with caution.
* CI runs tests `no-std`
* MSRV for `no-std` is 1.51 or so
