e30c492faf witness: clean up Debug implementation (Andrew Poelstra)
Pull request description:
The previous code seems to have been rebased/iterated on too many times, and had room for significant simplification. By inlining the indentation logic we can eliminate 40 LOC and also clean up the output by removing trailing spaces.
Fixes#1937
It is not good form to add unit tests for debug output but you can test this locally with the patch
```

9787ba6c96 Rename Script::empty to Script::new (Tobin C. Harding)
Pull request description:
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.

552f19abe3 Add more rustdocs to WitnessProgram (Tobin C. Harding)
89303c1464 Move witness types to the script module (Tobin C. Harding)
Pull request description:
This is done as part of an ongoing effort to improve the `address` module and `Address` type.
- Patch 1: Move `WitnessVersion` and `WitnessProgram` to their own modules within `script` - this is code move only except for the variant changes to the `address::Error` enum (see note below on `rustfmt` acting up).
- Patch 2: Improves documentation on the `WitnessProgram`
-
### Note on `rustfmt`
There are a bunch of formatting changes that shouldn't be in here, I stashed and re-ran the formatter a bunch of times but for some reason `rustfmt` wouldn't change `address` as it is but after I patched it `rustfmt` made a bunch of changes.

Add rustdocs to `WitnessProgram` commenting on why we carry the witness
version number around with the witness program. This is mainly a dev
comment but it helps document the invariants so make it a rustdoc
comment.
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.

- P2WPKH
- P2MS 2of3

TODOs:
- Add P2TR script-path multisig and key-path examples
- Are there mutisig transactions where flags are different for diff signatures within an input?
- Maybe switch to segwit_signature_hash()?
- Consider also verifying script hash if we go for full P2(W)SH transactions verifications?
