Merge rust-bitcoin/rust-bitcoin#1040: Introduce rustfmt in a non-invasive manner 

ee9a3ec6a1 Enable formatter for "src" (Tobin C. Harding)
743b197124 Add use for Unexpected (Tobin C. Harding)
fd217e72c3 Use f instead of formatter (Tobin C. Harding)
7b50a96ade Do not format prelude module (Tobin C. Harding)
01471f7e65 Shield hash_newtypes from rustfmt (Tobin C. Harding)
65d19d9044 Refactor compile_error message (Tobin C. Harding)
6461e2db8d Run formatter on examples/ (Tobin C. Harding)
fd1c6589ba Add a rustfmt configuration file with explicit ignores (Tobin C. Harding)

Pull request description:

  Looks like we are getting to a place that rustfmt _might_ be able to be used. In an effort to introduce `rustfmt` without requiring devs to do excessively mundane reviews introduce `rustfmt` in a non-invasive manner. What this means is

  - Add a fully fleshed out `rustfmt` config file that explicitly ignores all the source files
  - Enable sections of code one by one so review is easier (including preparatory patches before doing each section).

  This PR currently does `examples` and all the source files at the root level of the crate (i.e. excludes all directories in `src/`). The other directories can then be done one at a time.

  Please see discussion on: https://github.com/rust-bitcoin/rust-bitcoin/pull/959 for more context.
