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.
7001e93ad5 Fix clippy warnings (Tobin C. Harding)
Pull request description:
We have a bunch of clippy warnings on master, at least one of them is from a patch dated from March, before we ran clippy on CI.
Fix clippy warnings
- warning: accessing first element with `self.0.get(0)`
- warning: deref on an immutable reference
- warning: you are deriving `PartialEq` and can implement `Eq`
All one patch because clippy has to run cleanly for each patch on CI now.
Please note the `Eq` change, adding this derive is an API change.

Pull request description:
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`.
- Patch 1: Trivial preparatory cleanup
- Patch 2: Re-write bip143 test vectors using `sighash::SighashCache`
- Patch 3: Trivial, use `SighashCache` instead of `SigHashCache`
- Patch 4: Remove `SighashComponents` struct deprecated in 0.24.0
- Patch 5: Remove `MerkleBlock` methods deprecated in 0.26.2

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`?

Pull request description:
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`.

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).

Error variants should not end with the same identifier as the enum,
i.e., they should not stutter.
Found by clippy after setting:
avoid-breaking-exported-api = false
Clippy gives a warning about `wrong_self_convention` because we consume
self in a method called `is_*`. We have to consume self because the
object has a generic `E` (error type) that does not implement `Copy`.

This commit does two things:
1) BUG FIX: We should have checked that the length of the branch is 1
before computing the spend_info on it. This was introduced in #936, but
slipped past my review :(
2) Update the return type to return the consumed `self` value. This
function can only error when there the tree building is not complete.
Returning TaprootBuilderError causes issues in downstream projects that
need to deal with error cases which cannot happen in this function
405be52f5c Impl string conversion traits for `CommandString` (Martin Habovstiak)

071a1c02b7 Implement string parsing for `Sequence` (Martin Habovstiak)
c39bc3909d Extend `ParseIntError` to carry more context (Martin Habovstiak)
Pull request description:
When debugging parsing errors it's very useful to know some context:
what the input was and what integer type was parsed. `ParseIntError`
from `core` doesn't contain this information.
In this commit a custom `ParseIntError` type is crated that carries the
one from `core` as well as additional information. Its `Display`
implementation displays this additional information as a well-formed
English sentence to aid users with understanding the problem. A helper
function parses any integer type from common string types returning the
new `ParseIntError` type on error.
To clean up the error code a bit some new macros are added and used.
New modules are added to organize the types, functions and macros.
