Tobin Harding fa513bb5b5 Use expect for concensus_encode on engines
Calls to `unwrap` outside of tests are typically unfavourable.

Hash engines do not error when calling `consensus_encode`. Instead of
the current usage of `unwrap` we can use `expect` with a descriptive
string as is done in other parts of the codebase.

Tobin Harding a2efafcf9a Use error instead of err
In the name of uniformity use the same error message as argument to
`expect` througout the codebase.

Use "engines don't error" instead of "engines don't err".

Merge rust-bitcoin/rust-bitcoin#699: Huffman Bug Fix
f2a6827982 Fix BinaryHeap direction for Taproot Huffman Encoder (Jeremy Rubin)
cccd75d004 Fix Weighting Addition to never error on overflow + prevent overflows from ever happening with wider integers (Jeremy Rubin)

Pull request description:

  I noticed one cleanup & one bugfix while looking into the huffman algorithm:

  1) the cleanup: we can use a u128 to guarantee no overflows, and saturating_add to guarantee reasonable behavior in any case
  2) the bug: the binary heap is a max heap so the behavior ends up merging the nodes of the most likely entries repeatedly. a huffman encoder requires merging the least likely elements, so it should be reversed.

804a38cb67 Improve documentation of `WitnessVersion` (Tobin Harding)
eb8278fd2e util/address: Improve docs (Tobin Harding)

Pull request description:

  Improve documentation of the `address` module by doing:

  - Add full stops to all sentences
  - Use code ticks even inside links e.g., [`WitnessVersion`]
  - Use 100 character line length
  - Do grammar fixes
  - Use comment sections (e.g. `# Returns`)
  - Use 3rd person for function comments e.g. 'Converts foo to bar' instead of 'Convert foo to bar'
  - Use ticks for scriptPubkey

  This patch does a single file because a bunch of these changes pick an
  arbitrary stlye, if we can bikeshed on this PR then future PRs should be
  able to progress more quickly. I'll take lack of comment on any of the
  above as approval and I'll attempt to be uniform when doing the rest of
  the codebase. I plan on just chipping away at this, I can only do so
  much docs work in a day without getting bored of it :)

  Notes:

  - I didn't touch 'segwit' vs 'SegWit', seems both are widely used.
  - Using ticks inside links may be an overkill but seems more correct?
  - I'm not totally sure where the line is in the Rust ecosystem between
    readability in an editor and rendering as HTML, open to input on this.

Pull request description:

  Although the `bitcoin_merkle_root` and `bitcoin_merkle_root_inline`

Tobin Harding 822c99222d Improve constructor rustdocs for Address
Improve the rustdocs for the various `Address` constructors by putting
the brief description on a separate line with further description in its
own paragraph. This is the layout best practice for function documentation
using rustdocs.

Also, favour 'creates' over 'constructs' because it is more common in
the docs of this struct.

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 0e1b99359c Added fuzz test for `Script::bytes_to_asm_fmt`
This adds fuzz target for `Script::bytes_to_asm_fmt` which could

other panics.

Martin Habovstiak 49bd3af449 Refactor Script::bytes_to_asm_fmt to use iterator
This refactors `Script::bytes_to_asm_fmt`` function to use an iterator
instead of index. Such change makes it easier to reason about overflows
or out-of-bounds accesses. As a result this also fixes three unlikely
overflows and happens to improve formatting to not output space at the
beginning in some weird cases.

To improve robustness even better it also moves `read_uint`
implementation to internal function which returns a more specific error
type which can be exhaustively matched on to guarantee correct error
handling. Probably because of lack of this the code was previously
checking the same condition twice, the second time being unreachable and
attempting to behave differently than the first one.

Finally this uses macro to deduplicate code which differs only in single
number, ensuring the code stays in sync across all branches.
