4eedd46d58 Hotfix for secp256k1 alloc feature (Dr Maxim Orlovsky)
Pull request description:
Latest merges has broken builds since they have introduced `alloc` feature in `secp256k1` which appeared only in `0.20.3` version, while `Cargo.toml` here still required `0.20.2`
This was not caught by CI since it always runs with `cargo update`

`Instructions` guarantee to return `None` from empty iterator so we
should signal this in type system so that the code can be optimized
better. This also adds a test to make sure this property holds.

Pull request description:
Calls to `unwrap` outside of tests are generally unfavourable. We currently call `unwrap` in a bunch of places on calls to `consensus_encode` when passing writers that do not fail.
Remove `unwrap` calls on all calls to `consensus_encode` that pass a writer argument for which write functions do not fail. Use `expect` with a descriptive string instead.

Calls to `unwrap` outside of tests are typically unfavourable.
In memory writers (`Vec`) do not error. We can use `expect` with a
descriptive message string to indicate this.
Calls to `unwrap` outside of tests are typically unfavourable.
Sink writers do not error. We can use `expect` with a descriptive
message string to indicate this.
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.
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".
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.

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.

e04795093f Add unit test for bitcoin_merkle_root functions (Tobin Harding)
Pull request description:
We test `bitcoin_merkle_root` over in the `blockdata::block` module.
Although the `bitcoin_merkle_root` and `bitcoin_merkle_root_inline`
functions are almost identical there is enough index manipulation done
that it is not immediately obvious that the code is error free.
Add a unit test that verifies that the two functions return the same
resulting merkle root.
This was done in response to #394.

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.

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

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.
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.
