In an effort to make the library more ergonomic to use re-export modules
from `blockdata` at the crate root level. This helps to decouple the
internal code layout with the public API.
cc2c67fc2d Move sighash types to the sighash module (Tobin C. Harding)
7c040f4437 Refactor imports (Tobin C. Harding)
29f21d6ff5 Add additional sighash related pubic exports (Tobin C. Harding)
Pull request description:
This is non-urgent work, something I've wanted to do for months now, please only review at your leisure :)
Currently we have a bunch of sighash types defined in the `transaction` module and we have a newer `sighash` module that defines a bunch of related types. This is an artifact of the development process as we added the new types. If we put things that are related together it makes it easier for devs to find their way around the library and grok the code.
Move all the sighash types from the `blockdata::transaction` module to the `sighash` module.
The first two patches are preparatory cleanup.
### Labels
I added "API break" because I move the types without adding a re-export from the original place. I believe this is correct because we are, hopefully, aiming to de-couple the public API from the internal module structure so there is going to be a load more of this.

Pull request description:
Do error cleanups, and add a script to help find missing `non_exhaustive` on error types
- Patch 1: Audit the codebase and put `non_exhaustive` on all error types.
- Patch 2: Implement `std::error::Error::source` for `bip152::Error`
- Patch 3: Implement `Display` and `std::error::Error::source` for `MerkleBlockError`
- Patch 4: Move rustdocs to above attributes on one error type
- ~Patch 5: Add a python script to `contrib` that checks the codebase for missing non exhaustive on the line above the results of regex `pub enum .*Error`~
I removed the Python script patch, I can't be bothered working on this for now but the clean ups and `non_exhaustive` additions are useful IMO.
### labels
- I added 'API break', I think the `non_exhaustive` addition requires major bump but not sure?
- release notes mention is just for the `non_exhaustive` patch.

Currently we have a bunch of sighash types defined in the `transaction`
module and we have a newer `sighash` module that defines a bunch of
related types. This is kruft from the development process as we added
the new types. If we put things that are related together it makes it
easier for devs to find their way around the library and grok the code.
Move all the sighash types from the `blockdata::transaction` module to
the `sighash` module.
Refactor only, no logic changes.
Clean up some imports, only do the ones that we are about to touch.
- Remove/add whitespace to group by crate
- move modules/types to their module instead of using lib wide
re-export (this helps minimise future merge conflicts)
Re-order imports, refactor only. No logic changes.
We already export some of the sighash related types, there are others
that are uniquely named that can also be exported. Doing so makes use of
the library more ergonomic because devs do not have to know where types
are defined.
We just moved the `address` module out of `util` which is currently
ignored by `rustfmt`.
Run `rustfmt`, no other changes other than those made by the tool.
The identifier 'util' does not convey any information. We have a whole
bunch of modules inside the `util` module.
As part of work to reduce the amount of arbitrary things in the `util`
module move the `address` module to the crate root level.
We have formatting issues on master because we do not yet run the
formatter in CI (PR is open).
We are about to move the `address` module to `/src` which will require
running the formatter.
Run `cargo fmt` to fix formatting issues, no other changes.

I'm not sure what the exact policy we decided on for deprecating is but we have code deprecated since v0.24.0 and v.026.2, both of these seem reasonable safe to remove.
Removal of `SighashCompontents` uncovered the fact that we never moved the BIP 143 test vector code over to the new `SighashCache`.

6fa0329930 Re-order import statements (Tobin C. Harding)
Pull request description:
When we introduced the `SighashCache` we put encoding and sighash code
for segwit (v0 and taproo) in the `sighash` module. We also added
methods for legacy inputs that wrapped calls to encode/sighash methods
in the `transaction` module. This is confusing for a couple of reasons
- When devs read `Transaction` there are two methods that apparently
enable encodeing tx data and calculating the sighash but there is no
indication that these methods are only for legacy inputs.
- Once devs work out that segwit inputs have to be handled by methods on
the `SighashCache` it is not obvious why the methods on `Transaction`
exist at all.
Move the legacy encode/sighash code over to the `sighash` module and
deprecate the old methods. (Includes moving unit tests.)
Patch 1 and 2 are preparation.
(I did this work because I got lost in `Transaction::signature_hash` when messing with `TxOut::Amount` and trying to understand the signing algorithm vs bip143.
sanket1729 is there some other reason that I'm missing why we left the legacy code in `transaction`?

In attempt to resolve#1147 clean up the `bip158` module.
I was unable to resolve the `"confusing method names read and write that look like those from std:i:o::{trait}"`
I find the `bip158` data types and abstractions kind a funky but was unable to come up with any improvements.
Open question: Are all the public data types really meant to be public? Perhaps we should have an issue to write an example module that uses the bip158 module?

Refactor the `new_script_filter` by doing:
- Put it directly below the `new` constructor
- Improve docs
- Remove unneeded scope
- Correctly indent `where` keyword
Currently in the `bip158` module we do a bunch of dynamic dispatch using
the reader/writer objects. We can improve runtime performance, at the
cost of compile time, by using generics instead of dynamic dispatch.
The function `match_all` takes an iterator, it does not need to use the
`Seek` trait, we can just pass in the content as a slice, no need to
wrap it in a `Cursor`.

We are no using `non_exhaustive` on any error types unless we are

There are only three error enums that do not have it in the codebase as
of this commit, add it to all three.

The `bip143::SigHashCache` is deprecated in favour of
`sighash::SighashCache` however we still use it in `bip143` unit tests.
Use the new `sighash::SighashCache` in `bip143` unit tests.
We have a bunch of unit tests that verify the BIP 143 test vectors.
Three of these use the deprecated `SighashComponents` struct. We should
implement these tests using the new `SighashCache`. In order to do so we
have to move the tests to the `sighash` module so they can get access to
the private `segwit_cache()` function, and verify the cache internal
state against the test vectors.
Re-write the BIP 143 test vector code using `SighashCache` and remove
the versions using `SighashComponents`.
Done in preparation for removing the deprecated `SighashComponents`.

Pull request description:
[Turns out](https://github.com/rust-lang/rust-clippy/issues/9248) by default clippy does not lint certain parts of the public API.
Specifically, by setting `avoid-breaking-exported-api = false` we can get clippy to lint the public API for various things including
`wrong_self_convention`.
This means the saga of to/into/as continues ... we have used the wrong from for many of our `to_*` methods, they should consme `self`. Patch 1 fixes them. Patch 2 adds an `allow`. Patch 3 fixes a few error enum variant identifiers (removes `Error` suffix).
