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.
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.
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
This introduces some constants defined by Bitcoin Core which as a
consequence define some network rules in a new 'policy' module.
Only some were picked, which are very unlikely to change. Nonetheless a
Warning has been put in the module documentation.
Script-level constants are left into rust-miniscript where they are
already defined (src/miniscript/limits.rs).
It doesn't really make sense to have a constant for every common
script type's dust limit, instead we should just use the
`Script::dust_value()` function to have users calculate it.
The dust calculations added were only valid for P2WPKH and P2PKH
outputs, and somehow this fact was missed in review, despite the
upstream Core code being linked to and looked at by two reviewers
and the author (me).
Someday I will grow eyeballs, but that day is not today.
Right now, any sighash type could be parsed without error, which matches
consensus rules. However most of them would be invalid by standardness,
so it's a bit footgun-y (even more so for pre-signed transactions
protocols for which standardness is critical).
This adds `from_u32_standard()`, which takes care to error if we are
passed an invalid-by-current-policy-rules SIGHASH type.

Validating a block's proof-of-work involves computing the block hash.
Returning it from BlockHeader::validate_pow avoids having callers
recompute the block hash if it is needed.
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.
Instead of using a wildcard path for the `hash_types` module,
be explicit about what types we're using by using nested paths.
There are many benefits to this, including not polluting the namespace
and clearly demarcating the types' location.
- 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
