Stephen Finucane 4fc0a51a17 doc: Restructure docs for doc-migration
We have three populated sections:

- install
- user
- reference

There are three docs removed, as they served little useful purpose and
were mostly unreferenced.

Sphinx's 'warning-is-error' option is enabled to catch the few issues
that has snuck into the docs.
