Merge rust-bitcoin/rust-bitcoin#861: Remove get_ prefix
3bde1a205c Remove get_ prefix (Tobin Harding)

Pull request description:

  This one might be a viewed as code churn or unnecessarily modifying the API, feel free to NACK :)

  We have a bunch of methods that use the prefix `get_`, they are not exactly getters because they do more than just access a struct fields so Rust convention relating to getters does not apply, however, the `get_` prefix does not add to the descriptiveness of name hence the shorter form can be used with no loss of clarity.

  Improve docs and deprecate any methods changed that are pubic.

51a51cd67d Improve ClassifyContext rustdocs (Tobin Harding)

Pull request description:

  Improve the rustdocs on the `ClassifyContext` enum by doing:

  - Use link for `OP_RESERVED`
  - Use term `OP_SUCCESSx` is done in BIP342 (no code link, does not exist in code).
  - Use enum::variant form for both variant mentions
  - Direct readers to BIP342 for full list of opcode re-names

Merge rust-bitcoin/rust-bitcoin#860: Fix signature hash returned for sighash single bug
d1abfd9c30 Add unit test for sighash single bug (Tobin Harding)

3831816a73 Move test helper function (Tobin Harding)
3e21295b88 Remove unnecessary whitespace character (Tobin Harding)

Pull request description:

  Fix up the logic that handles correctly returning the special array 1,0,0,...,0 for signature hash when the sighash single bug is exploitable i.e., when signing a transaction with SIGHASH_SINGLE for an input index that does not have a corresponding transaction output of the same index.

  - Patch 1 and 2: Clean up
  - Patch 3: Implements the fix
  - Patch 4: Adds a passing test that fails if moved to before patch 3

  Resolves: #817

Tobin Harding 71cf00a314 Use less vertical lines
In this library we specifically do not use rustfmt and tend to favour
terse statements that do not use extra lines unnecessarily. In order to
help new devs understand the style modify code that seems to use an
unnecessary number of lines.

None of these changes should reduce the readability of the code.

Tobin Harding a5c06e0a96 Refactor vector initialisation
Vector initialisation uses neither "Block" nor "Visual" stlye, this is
irregular for no added benefit.

Elect to use "Block" style (as defined by `rustfmt`).

Tobin Harding a8ed95ea07 Refactor where statements
Our usage of `where` statements is not uniform, nor is it inline with
the typical layout suggested by `rustfmt`.

Make an effort to be more uniform with usage of `where` statements.
However, explicitly do _not_ do every usage since sometimes our usage
favours terseness (all on a single line).

Tobin Harding d1abfd9c30 Add unit test for sighash single bug
When signing a transaction will result in the sighash single bug being
exploitable we should return the 'one array' (equivalent to 1 as a
uint256) as the signature hash.

Add a unit test to verify we return uint256 1 value when use of
SIGHASH_SINGLE is invalid.

When signing a transaction will result in the sighash single bug being

as the signature hash.

Currently we are using the correct array value but are re-hashing it,
instead we should directly return it.

Merge rust-bitcoin/rust-bitcoin#869: Improve docs: script module
4dcbef6ddd Improve docs: script module (Tobin Harding)

Pull request description:

  Improve the docs in the `blockdata::script` module by doing:

  - Use full sentences (use capitals and full stops)
  - Improve grammar/wording if necessary
  - Remove incorrect/unneeded comments
  - Fix layout of rustdoc i.e., use brief and description sections
  - Use 100 line character width if it makes the comment look better
  - Use third person instead of imperative tense

  ## Note to reviewers

  Sorry to be a bore and request review on all these docs fixes, this one is all in a single patch which makes it a bit harder to review. It is very similar in content to all the others that are open right now so I'm going to be a bit rude and leave it like this. Please say if this is even slightly putting too much demand on you review time.

Tobin Harding f02b3a8472 Add code comment for emtpy input

this is correct.

bit stale (refer to deprecated types).

Instead of duplicating all the text, add a statement pointing readers
from the docs of `signature_hash` to the docs on
`encode_signing_data_to`.

Dr Maxim Orlovsky b9170162d5 Re-org keys and ecdsa mods - pt.1
This commit tries to achieve separation of signature- and key-related types, previously mixed in a single ECDSA module.

Rationale: bitcoin key types are not specific for signature algorithm.

This is achieved through
- Remove key mod with its content moved to ecdsa mod
- Re-export keys under key module in util mod - to make git generate diff for the rename of ecdsa mod in the next commit correctly.
