Once the initial work is in, I'm going to start moving in directory-by-directory documentation for the rest of the code.

The next section of work here is in a branch called doxygen_libs, with PR at https://github.com/torproject/tor/pull/1493

It begins moving documentation from doc/HACKING/design into our source code reference, and covers all of src/lib. We should also write some topic-specific items; they will need their own pages.

Trac:
Status: accepted to needs_review

I've extended the branch and the PR to cover each directory.

Minor tweaks I pointed out in the PR. After those, feel free to merge.
