facaefc49c Add conversions for TweakedKeyPair -> TweakedPublicKey (Tobin C. Harding)
2407f241e4 Remove sep256k1 path from Parity (Tobin C. Harding)
Pull request description:
It is trivially possible to get `TweakedPublicKey` from a `TweakedKeyPair`, add conversion methods for doing so.
Patch 1 is preparatory cleanup. Please note `From` is not implemented because the conversion returns the `Parity` also.

From BIP143:

Currently we are using a `Sighash` which wraps double sha256 so while technically correct this means we are relying on `Sighash` to implement `Encodable`. We can remove this requirement by directly using the `sha256d::Hash` type to hash the outputs data.

e7bbfd3913 Improve Psbt error handling (DanGould)
Pull request description:
## Separate `encode::Error` and `psbt::Error` recursive dependency
This initial work attempts to fix#837's first 2 points
> - The current psbt::serialize::Deserialize has an error type of consensus::encode::Error. I think we should cleanly separate consensus encoding errors from application-level encoding errors like psbt.
> - There is a recursive dependence between encode::Error and psbt::Error which would need to be cleanly dissected and separated so that there is no dependence or only one-way dependence.
## Better `ParseError(String)` types
arturomf94 how compatible do your #1310 changes look to address #837's third point with this design?
> - There are a lot ParseError(String) messages that could use a better type to downflow the information.
I think your prior art would completely address this issue now.
## On handling `io::Error` with an associated error
`encode::Error` has an `Io` variant. now that `Psbt::deserialize` returns `psbt::Error` and produces an `io::Error`, we need an `Io` variant on `psbt::Error`. Except that doing so breaks `#[derive(Eq)]` and lots of tests for `psbt::Error`.
Kixunil, I'm trying to understand your feedback regarding a solution to this problem.
> I believe that the best error untangling would be to make decodable error associated.
> I meant having associated `Error` type at `Decodable` trait. Encoding should only fail if the writer fails so we should have `io::Error` there (at least until we have something like `genio`).
>
> > [it] is a problem to instantiate consensus::encode::Error in [the psbt] module for `io::Error`?
>
> It certainly does look strange. Maybe we should have this shared type:
>
> ```rust
> /// Error used when reading or decoding fails.
> pub enum ReadError<Io, Decode> {
> /// Reading failed
> Io(Io),
> /// Decoding failed
> Decode(Decode), // consensus and PSBT error here
> }
> ```
>
> However this one will be annoying to use with `?` :( We could have `ResultExt` to provide `decode()` and `io()` methods to make it easier.
>
> If that's not acceptable then I think deduplicated IO error is better.
Kixunil didn't we just get rid of Psbt as `Decodable`? Would this make more sense to have as an error associated with `Deserialize`? Or did we do the opposite of what we should have by making Psbt only `Serialize`/`Deserialize` because of #934, where only consensus objects are allowed to be `Decodable`? I wonder if we prioritized that strict categorization and are stuck with worth machinery because of it. My goal with #988 was to get to a point where we could address #837 and ultimately implement PSBTv2.

ebfbe74243 Implement `Debug` for generic `Address<V: NetworkValidation>` (Jiri Jakes)
Pull request description:
Previously `Debug` was implemented for both `Address<NetworkChecked>` and `Address<NetworkUnchecked>`, but not for cases when the `NetworkValidation` parameter was generic. This change adds this ability. Based on Kixunil's tip.
With previous implementation, the `test_address_debug()` resulted in error:
The added `Debug` on `NetworkChecked` and `NetworkUnchecked` are required by compiler.
---
While dealing with derives and impls, I also attempted to turn all the derives on `Address` into manual impls (see Kixunil's suggestion in https://github.com/rust-bitcoin/rust-bitcoin/pull/1489#discussion_r1052448057). The motivation behind this was the possibility to remove derives on `NetworkChecked` and `NetworkUnchecked`, too. However, even with manual impls, all the traits on `NetworkChecked` and `NetworkUnchecked` were still required by compiler in this sort of situations (see also the rest of the same discussion linked above). I do not fully understand why, perhaps limitation of this way of sealing traits?
It can be demonstrated by removing `Debug` derivation on `NetworkUnchecked` and `NetworkChecked` in this PR and running `test_address_debug()`.
Therefore, if we want to allow users of the library to define types generic in `NetworkValidation` and at the same time derive impls, it seems to me that `NetworkChecked` and `NetworkUnchecked` will have to have the same set of impls as `Address` itself.

`Sighash` does not need to implement `Encodable` because it is
claimed (I don't know exactly myself) that `Sighash` is never consensus
encode in Bitcoin.
We are currently relying on `Sighash` to implement `Encodable` when
encoding creating the segwit v0 sighash for a single input.
For reference, from BIP143:
If sighash type is SINGLE and the input index is smaller than the
number of outputs, hashOutputs is the double SHA256 of the output
amount with scriptPubKey of the same index as the input;
We can use `write_all` directly to write the hashed bytes and remove the
implementation of `Encodable` from the `Sighash` type.
While we are at it, use `write_all` to write the zero hash also to make
the code more uniform and understandable.

Recently we introduced some mutation testing to the `pow` module but
testing is never done - add more `mutate` attributes and add unit tests
to ensure all mutants are killed.
Of note, the `from_compact` and `to_compact_lossy` functions are not
done, doing so results in a bunch of surviving mutants.
