Licenses are boring as hell, so is are all the comments at the top of
each file. This patch makes no comment on the merit of license comments
in each file, rather this patch reduces the license comment to the
minimum possible with no loss of meaning - an SPDX license identifier.
Note also please that we remove the "written by" comments as well for
the following reasons (discussed recently on rust-bitcoin repo):
- they are not descriptive because many devs contributed
- they have a tendency to include the wrong date because of cut'n'pasta
- all this info is in the git history

Run the command `cargo +nightly fmt` to fix formatting issues.
The formatter got confused in one place, adding an incorrect
indentation, this was manually fixed.
Clippy default settings seemed to have changed introducing a few new
warnings.
warning: variable does not need to be mutable
warning: deref on an immutable reference
warning: returning the result of a `let` binding from a block
Fix them all in a single patch because CI has to pass for each patch.
`Default` was pointless, so it was replaced with internal
`from_raw_parts` method which also checks the length.
This commit also documents changes to `SerializedSignature`.
Closes#454
This de-clutters the code and prepares for the next step of adding
`IntoIterator`. The type is still re-exported so the change is neither
breaking nor inconvenient.
This also adds more datialed explanation of `SerializedSignature` and
why it's needed.
