Merge rust-bitcoin/rust-bitcoin#1581: Use ignore to stop rustdoc code from being built
6d99d3c061 Use ignore to stop rustdoc code from being built (Tobin C. Harding)

Pull request description:

  Currently we have an attempted tag ```compile_fail that seems to be aiming at allowing code that does not build to exist in rustdoc. This is causing an error when running tests.

  No clue how this made it through CI.

  Use ```ignore to prevent rustdoc code from being built.

Merge rust-bitcoin/rust-bitcoin#1592: Add `From<Address>` for `ScriptBuf`
5f86b3091c Add From<Address> for ScriptBuf (Tobin C. Harding)

Pull request description:

  Add an implementation of `From<Address> for ScriptBuf` that calls through to `address.script_pubkey` (which calls
  `address.payload.script_pubkey()`).

Martin Habovstiak 6be89bf94f Add `minimal_non_dust` to `TxOut`
In some scenarios it's useful to create outputs with minimal relayable
value. E.g. outputs designated for fee bumping using CPFP. A method for
this is useful.

This implements a constructor of `TxOut` that computes the minimal
non-dust value from the passed script.

Closes #1459

Martin Habovstiak cf068d16b0 Implement transaction weight prediction
When creating a transaction one must know the the fee beforehand to set
appropriate amounts for outputs and to know the fee, weight is required.
So far we only had a method on an already-constructed transaction. This
method clearly wasn't helpful when constructing the transaction except
for hacks like temporarily adding an all-zeroes signature.

This change adds a function that can compute the transaction weight
without knowing individual bytes of the scripts, witnesses and other
elements. It only needs to know their sizes.

To make the API less error-prone a special, trivial, type is also added
for computing the lengths of witnesses.

Pull request description:

  Currently the docs build commands in `hashes` and `bitcoin` differ, they should be the same.

  Add a command `cargo doc` to improve coverage e.g., recently we botched the feature guarding but since CI only runs `cargo rustdoc` with custom compiler conditional set we didn't catch it.

  Done after seeing: https://github.com/rust-bitcoin/rust-bitcoin/pull/1504 and CI should fail on this PR until 1504 is in.

Pull request description:

  Patch one does the deprecation, the rest of the PR is made up of tiny improvements to the code around reading/writing 'scriptint's (conceptually `CScriptNum`s). I did all this while trying to decipher the discussion on #1547.

  ### Note Please

  There are many more changes in the pipeline for all this read/write "script int" stuff. This PR was done ages ago and I believe it stall adds value.

  I re-did the whole PR manually because of the recent `script` module changes. I hope no one else has to do that - if you do please feel free to holla and I'll "rebase" your PR for you.

  Do a complete overhaul of the manifest of the top level crates (i.e., not `embedded`, `fuzzing` ect.).

  Many of the problems being fixed here were introduced over the last year by my poor understanding of exactly what was going on with _every_ line of code in the manifests, after this PR I hope that is no longer a problem.

  I'm closing #1571 because it is now done more fully at the end of this PR.

  During review please be liberal with any questions so we can ensure everything is spot on now - as we add more crates there are going to be a proliferation of manifest files, best get it right now.

  PR 2 in the `merkle_tree::block` series, used to be on top of the now merged #1374.

  Do a bunch of refactorings in preparation for more invasive changes. This is a separate PR because, other than the first patch which moves hex strings to `tests/data/` the other patches are refactoring only patches, no logic changes. However the last patch is big and will be annoying to review - sorry about that. If you really oppose this basically stylistic patch putting important things first, the opposite of C code, please say and I'll try to stop doing it.

Merge rust-bitcoin/rust-bitcoin#1600: Refactor script module
a9108d3939 Refactor script module (Tobin C. Harding)

Pull request description:

  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.

  ## Note to reviewers

  This PR is impossible to review from the diff because it moves so much code. Perhaps better to look at the resulting `src/blockdata/script/` directory and see if you like it.

  #### Motivation

  While adding script tagging I was having difficulty navigating the script module.

- 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.

  "Sighash" is a technical term that newbies in Bitcoin may not know and could get lost when trying to find how to sign a transaction. This change attempts to make it more obvious that this module is needed for signing.

Merge rust-bitcoin/rust-bitcoin#1608: Set `rustv_1_53` in build script
bb612fdafa Set rustv_1_53 in build script (Tobin C. Harding)

Pull request description:

  The rust version is supposed to be set by the build script so that users automagically get features matching the toolchain in use. Currently we have a feature in the manifest for `rustv_1_53` instead setting a compiler conditional configuration option in the build script. This causes `cargo +1.41.1 --all-features check` to fail.

  ## Note

  I don't see `rustv_1_46` used anywhere, do we need that still?

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.
