Merge rust-bitcoin/rust-bitcoin#1968: Add max standard tx weight constant to transaction
2e3006a729 Add max standard tx weight constant to transaction (yancy)

Pull request description:

  Add a constant for the max transaction weight.  Similar to [max block weight](1b009b809b/bitcoin/src/blockdata/weight.rs (L35)).  This value is pulled from core  [here](44b05bf3fe/src/policy/policy.h (L27))

Merge rust-bitcoin/rust-bitcoin#1947: Add absolute fee rate convenience functions to `FeeRate`
9eff2f2f5e fee_rate: Add public absolute weight convenience functions (Tobin C. Harding)
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

Improve the ScriptHash and WScriptHash types
Improve the script hash types by doing:

- Define the types in the `crypto::script` module
- Put the From impls directly below the type definitions

Keep the current crate level re-export so this does not impact the
public API _if_ people are using the re-export but is still a breaking
change.

Use standard set of derives on all error types
As part of an ongoing effort to make our error types stable and useful
add a stand set of derives to all error types in the library.

    `#[derive(Debug, Clone, PartialEq, Eq)]`

Add `Copy` if possible and the error type does not include
`#[non_exhaustive]`.

If an error type includes `io::Error` it only gets `#[derive(Debug)]`.

Pull request description:

  The current derived debug implementation on `Witness` prints the content field as an array of integers. We can do better than this by manually implementing `Debug`.

  With this applied `Witness` is printed as follows: (first line is `{:?}` and the next is `{:#?}`):

  Using `{:?}`:
  ```
  Witness: { indices: 3, indices_start: 8, witnesses: [[0x00], [0x02, 0x03], [0x04, 0x05]] }
  ```

  Using `{:#?}`:
  ```
  Witness: {

      indices_start: 8,
      witnesses: [
          [0x00],

Move witness types to the script module
From BIP 141:

> A scriptPubKey (or redeemScript as defined in BIP16/P2SH) that
> consists of a 1-byte push opcode (for 0 to 16) followed by a data push
> between 2 and 40 bytes gets a new special meaning. The value of the
> first push is called the "version byte". The following byte vector
> pushed is called the "witness program".

`WitnessVersion` and `WitnessProgram` are scriptPubkey concerns and
scriptPubkey is basically synonymous with address so in one way it makes
sense that these types are in `address` however we are in the process of
overhauling the `Address` (and `AddressInner`) types so lets move the
witness stuff to `script` and put it in individual sub-modules.

This move helps simplify the address error type also.

Note please, there are a bunch of formatting changes in here in the
error type that I cannot explain and could not remove.

Manually implement Debug on Witness
The current derived debug implementation on `Witness` prints the content
field as an array of integers. We can do better than this by manually
implementing `Debug`.

With this applied `Witness` is printed as follows: (first line is `{:?}`
and the next is `{:#?}`):

Using `{:?}`:
```
Witness: { indices: 3, indices_start: 8, witnesses: [[0x00], [0x02, 0x03], [0x04, 0x05]] }
```

Using `{:#?}`:
```
Witness: {
    indices: 3,
    indices_start: 8,
    witnesses: [
        [0x00],
        [0x02, 0x03],
        [0x04, 0x05],
     ],
}
```

Rename Script::empty to Script::new
The `empty` constructor is mis-named for the following reasons:

- Non-uniform with `ScriptBuf::new`
- Non-standard with respect to stdlib which uses `Path::new` and
  `PathBuf::new` (on which we based the `Scritp`/`ScriptBuf`)

Rename the function to `new`, put it at the top of the impl block while
we are at it.

Remove doc(hidden) from error conversion functions
Give people access to the error type conversion docs, its no harm and it
may be useful when the compiler does not give enough information.

Add block::ValidationError
Add a `ValidationError` to the `block` module and remove the two
variants out of `crate::Error`.

This error is only used by the `validate_pow` function, a specific error
better serves our purposes.
