Major code cleanup.

I have made lots of changes, including transitioning most data
structures to use def-komtype, removing functions that weren't used
(there are several left), removing almost all the remaining who-buffer
remnants and generally messing with things.

Chances are I broke something. I haven't figured out what yet, but do
let me know if you spot anything.
