Fix compilation warnings.

This is mostly reflowing / reworkding docstrings to keep within 80
characters limit and adding autoloads.

There are two warning remaining that I don't understand:
- mastodon-async.el:359:16: Warning: reference to free variable
‘url-http-end-of-headers’
- mastodon-http.el:139:8: Warning: value returned from (string-equal json-string "") is unused

When adding autoloads this sorts them for better readability.
