73bc2bb058 Remove leading colons from ::core::cmp::Ordering (Tobin C. Harding)
bffe0e840d Remove _most_ leading double colons (Tobin C. Harding)
Pull request description:
Leading double colons are a relic of edition 2015. Attempt to remove _all_ leading double colons (assuming I didn't miss any).
- Patch 1 is done mechanically so it can be repeated by reviewers, just search-and-replace ' ::' with '::' (note the leading space).
- Patch 2 does a single other instance of leading `::`

91ff2f628c Introduce SPDX license identifiers (Tobin C. Harding)
Pull request description:
When `rust-bitcoin` was started in 2014 the SPDX license list and short identifiers where not a thing. Now that we have short identifiers and they are gaining popularity in other projects we can consider using them.
- Add links to the SPDX website in the readme
- Shorten the author section to a single line
- Remove all the licence information in each file and replace it with an
SPDX ID (see https://spdx.dev/ids/#how)
Of note:
- If the author of a file is explicitly listed, maintain this information
- If the 'author' is listed as the generic 'Rust Bitcoin developers' just remove the attribution, this is implicit. This does loose the date info but that can be seen at any time from the git index using
`git log --follow --format=%ad --date default <FILE> | tail -1`
apoelstra, please confirm that I'm not treading on your toes here, especially, are you ok with the new 'written by' string format?

Leading double colons are a relic of edition 2015. Remove all leading
double colons that follow a space, done like this so that reviewers can
do the same and verify the diff. Done with
search-and-replace ' ::' '::'

Pull request description:
As part of the ongoing error improvement work and as a direct result of [this comment](https://github.com/rust-bitcoin/rust-bitcoin/pull/987#issuecomment-1135563287) improve the `Display` implementations of all our error types so as to not repeat the source error when printing.
The first 5 patches are trivial clean ups around the errors. Patch 6 is the real work.
EDIT: ~CC @Kixunil, have I got the right idea here bro?~ Patch 6 now includes a macro as suggested.

2e7effc604 Feature `use-serde` renamed to `serde` (Martin Habovstiak)

Sadly, derive can't see that the crate was renamed so all derives must
be told to use the other one.

99f565f932 Add non_exhaustive to all error enums (Tobin C. Harding)
Pull request description:
Adding an error variant to a public enum is an API breaking change, this means making, what could be, small refactorings or improvements harder. If we use `non_exhaustive` for error types then we mitigate this cost.
There is a tradeoff however, downstream users who explicitly match on our public error types must include a wildcard pattern.

means making what could be small refactorings or improvements harder. If
we use `non_exhaustive` for error types then we mitigate this cost.
There is a tradeoff however, downstream users who explicitly match on
our public error types must include a wildcard pattern.
We implement `source` for all our error types. This means that we should
not display the source error explicitly because users can call `source`
to get the source error.
However, `std::Error::source()` is only available for "std" builds, so
that we do not loose the error source information in "no-std" builds add
a macro that conditionally adds the source onto the error message.
Features activating external crates are supposed to have same name as
those crates. However we depend on same feature in other crates so we
need a separate feature. After MSRV bump it is possible to rename the
