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.
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.

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.

Pull request description:
Adds https://github.com/bitcoin/bips/blob/master/bip-0341.mediawiki message signature algorithm
The base is taken from `bip143::SigHashCache`, some code results duplicated but I think it's more clear to keep things separated
Would mark some bullet point on https://github.com/rust-bitcoin/rust-bitcoin/issues/503
Test vectors are taken by running d1e4c56309/test/functional/feature_taproot.py with a modified `TaprootSignatureHash` function to print intermediate values that I cannot found in the bip341 [test vector json](https://raw.githubusercontent.com/bitcoin-core/qa-assets/main/unit_test_data/script_assets_test.json)
UPDATE: Latest version includes the suggestion from @sanket1729 to create a unified tool for signature message hash for legacy, segwit, and taproot inputs. In particular, makes sense for mixed segwit v0 and taproot v1 inputs because cached values could be shared

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.
This refactors the code to make it possible to use `get_or_insert_with`
instead of unwrapping in `segwit_cache()`. To achieve it `common_cache`
is refactored into two functions: one taking only the required borrows
and the original calling the new one. `segwit_cache` then calls the new
function so that borrows are OK.
Apart from removing unwrap, this avoids calling `common_cache` multiple
times.
There was a question whether this is equally performant. There are
multiple good reasons why it should be:
1. `get_or_insert_with` is marked `#[inline]`
2. Any good optimizer will inline a function that is used exactly once
3. 1 and 2 conclude that the closure will get inlined
4. Computing self.tx can then be moved to the only branch where it is
required.
5. Even if get_or_insert_with didn't get optimized, which is extremely
unlikely, the `tx` field is at the beginning of the struct and it
probably has pointer alignment (`Deref` suggests it's a pointer).
Alignment larger than pointer is not used, so we can expect the
fields to be ordered as-defined. (This is not guaranteed by Rust but
there's not good reason to change the order in this case.) We can
assume that offset to tx is zero in most cases which means no
computation is actually needed so the expression before closure is
no-op short of passing it into the closure as an argument.
At the time of writing `#[inline]` can be seen at
https://doc.rust-lang.org/src/core/option.rs.html#933
Instead of using magic numbers we can define constants for the address
prefix bytes. This makes it easier for future readers of the code to see
what these values are if they don't know them and/or see that they are
correct if they do know them.

*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
Fixes#608. In #567 the Display impl for ChildNumber was
consciously changed, assuming the semver break would not
affect any correctly implemented downstream projects. We
were wrong.
This is instead of encode::Errors because the encoders should
not be allowed to return errors that don't originate in the writer
they are writing into.
This is a part of the method definition that has been relied upon for a
while already.
- Rename the `iter` method to `instructions`.
- Add `instructions_minimal` for minimal-enforced iteration.
- Iterator has `Result<Instruction, Error>` as items.
Taking an external dependency just to convert ints to byte arrays
is somewhat of a waste, especially when Rust isn't very aggressive
about doing cross-crate LTO.
Note that the latest LLVM pattern-matches this, and while I haven't
tested it, that should mean this means no loss of optimization.
* add client side block filters with code from murmel. use siphash from bitcoin_hashes pass Bitcoin Core tests upgrade to bitcoin_hashes 0.7
* add filter.filter_id() test use BlockFilter directly
* fixed edge cases of matching empty query sets or or using empty filter
For p2wsh the scriptCode is the witness script, but for p2wpkh, it's the
equivalent legacy p2pkh output script.
The name scriptCode is used in the BIP, so it's less confusing.
This is a port of the bitcoin-core CPartialMerkleTree and CMerkleBlock classes.
Here they are called PartialMerkleTree and MerkleBlock.
These are useful for SPV clients that wish to verify that a transaction is
present in a specific block in an authenticated way.

We continue to support only compressed keys when doing key derivation,
but de/serialization of uncompressed keys will now work, and it will
be easier/more consistent to implement PSBT on top of this.
This change also moves the secp256k1::Error wrapper from util::Error to
consensus::encode::Error, since we do not use it anywhere else. We can
add it back to util::Error once we have instances of secp256k1::Error
that are not related to consensus::encode.

Previously this structure was unused, it's now being used by the `TxIn`
structure to simplify the code a little bit and avoid confusions. Also
the rust-lightning source code has an `OutPoint` similar to this one
but with the `vout` index as an `u16` to avoid unsafe conversions.
I've added to new methods to `OutPoint`:
- `null`: Creates a new "null" `OutPoint`.
- `is_null`: Checks if the given `OutPoint` is null.

The `serde_struct_impl!` macro has been modified to be compatible
with the serde 1.0 crate, we use this macro and not the `serde_derive`
crate because the latter doesn't support Rust 1.14.0 which is shipped
on Debian stable and we should remain compatible with it.
Two new features were added:
- "serde": enables serialization/deserialization for common types, it pulls
the serde 1.0 dependency.
- "serde-decimal": enables serialization/deserialization for `UDecimal`/`Decimal`,
this pulls the strason 0.4 depdendency and the serde 1.0 dependency.
