Refactor script module
The `script` module is large and unwieldy.

Refactor the `script` module, splitting it up into a tree of modules.
Here are a few of the changes and their stated benefits

- Split the two script types out into separate files: Readers of the
methods can then tell immediately from the file name which type they are
reading.
- Put all the impls for the two script types together: Makes parsing the
API easier because one can more quickly see which traits are implemented
on what i.e., all the `AsRef` imlps are grouped together.
- Put the impls for the two script types in order, first `Script` then
`ScriptBuf`: Makes it easier for us to see if we missed something.
- Put the `Builder` and `Instruction` (and associated) types in their
own modules: Some devs find long files hard to navigate, so far there
hasn't been too much push back against short files.
- Put tests in a separate file: This idea was recently discussed.

This is only moving code and fixing import statements etc. No other
changes to the code.

Rename from_slice methods to decode
The `TaprootMerkleBranch` and `ControlBlock` both have methods on them
called `from_slice` but these methods do more that just basic copy from
a slice. `decode` is a more descriptive name.

Deprecate the `from_slice` methods and implement `decode`, on other
changes to the logic.

Martin Habovstiak b3188bbac3 Add `Transaction` accessors to `SighashCache`
It may be useful to access the transaction stored in `SighashCache`
during signing or afterwards, especially when the transaction is stored
without indirection (to enable long-lived storage).

This change adds the appropriate accessors.

Martin Habovstiak 7c6854fe02 Use `Borrow` instead of `Deref` in `SighashCache`
The requirement for a type dereferencing to `Transaction` prevented
storing the cache in long-lived data without resorting to silly
wrappers. Since `Borrow` is implemented both for `T` and for smart
pointers it's a more flexible bound which this change implements.

While this is technically breaking, all usual non-generic code will
continue to work beause smart pointers generally have `Borrow`
implemented.

Pull request description:

  This work started out, as the branch name suggests, as an effort to use the `hex_lit` crate. But once I got to this stage it seems that the `hex!` macro we have provides different, useful, functionality than the `hex_lit::hex!` macro (it allows usage with non-consts). So I'm unsure if we want to remove it now.

  - Patches 1 - 6 are preparatory clean ups
  - Patch 7 reduces usage of  `FromHex`, please see git log for full description
  - Patch 8 removes `hex_from_slice` and fixes a bug in how we display `Sighash`

Remove hex_from_slice and display Sighash forwards
`Sighash` should be displayed forwards according to BIP143. Currently we
are displaying it backwards (as we do for double SHA256). This is
working because parse using `Vec::from_hex`.

We have the means to parse hex strings directly for hashes, we no longer
need `hex_from_slice`.

BIP143 test vectors display double SHA256 forwards but we display
backwards, this is acceptable because there is no fixed display in the
ecosystem for double SHA256 hashes. In order to overcome this we parse
test vector hex strings with into `Vec` when needed.

hashes: Implement AsRef for fixed size arrays
Implement `AsRef<[u8; X]>` for hash types including wrapped hash types.
Doing so means at times the compiler can no longer infer the type because we have
`AsRef<[u8]` implemented also but we can use `into_inner` and `as_inner`
to get the inner array if needed.

  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.

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.

Merge rust-bitcoin/rust-bitcoin#1578: Implement `Debug` for generic `Address<V: NetworkValidation>`
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:

  ![image](https://user-images.githubusercontent.com/1381856/213907042-f1b27f41-fa46-4fa0-b816-cc4df53f5d29.png)

  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.

Use write_all for sighash encoding
`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.

compiler in enforcing this validation.

We use `internals::hex::display::DisplayHex` in many places, we can
improve ergonomics of the `internals` crate by re-exporting it from the

  Instead of using consensus {de,en}code, serialize high-level structures (PartiallySignedTransaciton, Output, Input) borrow the signature from `Serialize`, `Deserialize` traits and implement them on Psbt:

  ```rs
  impl Psbt {
      /// Serialize a value as raw data.
      fn serialize(&self) -> Vec<u8>;

      /// Deserialize a value from raw data.

Merge rust-bitcoin/rust-bitcoin#1438: Replace `Vec::from_hex` with `hex!`
089a1e452d Replace `Vec::from_hex` with `hex!` (Martin Habovstiak)

Pull request description:

  This makes the code less noisy and is a preparation for changing it to `const`-based literal. Because of the preparation, places that used variables to store the hex string were changed to constants.

  There are still some instances of `Vec::from_hex` left - where they won't be changeable to `const` and where `hex!` is unavailable (integration tests). These may be dealt with later.

  See also #1189

  Note that while the change appears big it's nearly entirely mechanical, so should be pretty easy to review. (But I don't feel it's `trivial`.)

Martin Habovstiak 8d58ee2ca3 Change `#[cfg(docsrs)]` to `#[cfg(doc)]` on `use`
The additional `use` items were added to improve the style of
documentation. Because they were only used for doc they were `cfg`ed.
But because this is independent from being built by `docs.rs` the `cfg`
should've been `doc` not `docsrs`.

IOW `docsrs` means roughly `all(doc, nightly)` and the added items are
unrelated to `nightly`.

Pull request description:

  This PR uncovered incorrect feature gating in `secp256k1`, fixed in https://github.com/rust-bitcoin/rust-secp256k1/pull/519

  Currently we enable "secp256k1/rand-std" in the "rand" feature, this is incorrect because it means "rand" implies "std" which it does not.

  Add a "rand-std" feature that turns on "seck256k1/rand-std" and make the "rand" feature turn on "seck256k1/rand".

Pull request description:

  This fixes several API bugs:

  * Use `TryFrom` instead of `From` for fallible conversions
  * Move byte conversion methods from `impl_array_newtype` to `impl_bytes_newtype`
  * Add missing trait impls like `AsRef`, `Borrow`, their mutable versions and infallible conversions from arrays

  Closes #1336

  Notably this change is much less bad than even I expected and some places actually get cleaner than before.
