Implements highlighting of shortlinks like cl/123, or b/123.
Highlighting works by replacing the input Markdown using a simple
regular expression replacement.
We also considered parsing and replacing these links in the Markdown
AST, but it would have been significantly more complex (due to arena
allocation) for little upside and no obvious performance benefit.

Sourcegraph uses a component called syntect_server to syntax-highlight
source files.
Since we already have custom syntaxes, overrides and configuration we
might as well use them with Sourcegraph!
This implements the syntect_server "protocol" (it's just a single
endpoint) so that we can swap out the syntect_server component with
cheddar.
Note: There's a few clippy lints here, but they're being solved in a
followup commit because I wanted to take care of all of them at
once (not just the ones introduced in this change).

The complexity of the arg parsing is increasing somewhat because we're
adding more features to cheddar, so to set us up for that this
switches the arg parsing to the somewhat more flexible clap.

Generalises the two bits of the program that will be required either
way (extension parsing and syntax loading).
A dependency on Comrak is introduced as I think GitHub-flavoured
Markdown (with all its fancy extensions) is desirable!
The first step with this tool will be to use it as a source-filter for
cgit. The second step is to use it as the Markdown renderer by
depending on one of the Markdown libraries, with integration for
rendering code snippets directly.
