Merge rust-bitcoin/rust-bitcoin#1999: Fix witness display bug
84614d9997 Unit test debug print of witness with empty instruction (Tobin C. Harding)
e96be5ee6e Fix Witness debug display bug (Tobin C. Harding)

Pull request description:

  When we introduce a custom `Debug` implementation for the `Witness` we introduced a bug that causes code to panic if the witness contains an empty instruction.

  The bug can be verified by putting patch 2 first or by running `cargo run --example sighash` on master.

Pull request description:

  In preparation for `hashes` release, bump the version. Depend on new version in `rust-bitcoin`.

Add VarInt from implementations by way of macro
Throughout the codebase we cast values to `u64` when constructing a
`VarInt`. We can make the code marginally cleaner by adding `From<T>`
impls for all unsigned integer types less than or equal to 64 bits.
Also allows us to (possibly unnecessarily) comment the cast in a single
place.

Remove usage of ThirtyTwoByteHash
The `ThirtyTwoByteHash` trait is defined in `secp256k1` and used in
`hashes` as well as `bitcoin`. This means that we must use the same
version of `hashes` in both `bitcoin` and `secp256k1`. This makes doing
release difficult.

Remove usage of `ThirtyTwoByteHash` and use `Message::from_slice`.
Include TODO above each usage because as soon as we release the new
version of secp we can use the new `Message::from_digest`.

This is step backwards as far as type safety goes and it makes the code
more ugly as well because it uses `expect` but thems the breaks.

f00e93bdcd Fix typos in rustdoc (Tobin C. Harding)
f3412325ea weight: Make docs uniform and terse (Tobin C. Harding)

Pull request description:

  - Patch 1 is docs cleanup
  - Patch 2 adds two functions to `FeeRate`

  From the commit log of patch 2:

      Calculating the absolute fee from a fee rate can currently be achieved
      by creating a `Weight` object and using
      `FeeRate::checked_mul_by_weight`. This is kind of hard to discover, we
      can add two public convenience functions that make discovery of the
      functionality easier.

      Add two functions for calculating the absolute fee by multiplying by
      weight units (`Weight`) and virtual bytes (by first converting to weight
      units).

  This seems like an obvious thing so I'm inclined to think that Kixunil left it out for a reason. (Mentioning you here Kix so even if this merges you'll see it in notifications later on.)

Pull request description:

  EDIT: The commit hashes below are stale but the text is valid still.

  In an effort to "perfect" our error handling, overhaul the error handling in the `crypto` module.

  The aim is to do a small chunk so we can bikeshed on it then I can apply the learnings to the rest of the codebase.

  Its all pretty trivial except:

  - commit `4c180277 Put NonStandardSighashTypeError inside ecdsa::Error variant`
  - comimt `5a196535 Add InvalidSighashTypeError`
  - commit `05772ade Use defensive documentation`

  Particularly the last one might be incorrect/controversial.

  Also, please take the time to check the overall state of error code in the `crypto` module on this branch in case there is anything else we want to do.

  Thanks
