*: refactor all the things

Long overdue house cleaning.

The addition of compositing/monitoring overlays in vwm3 pushed vwm well past
what is a reasonable size for a simple thousand line file.  This is a first
step towards restoring sanity in the code, but no behavioral differences are
intended, this is mostly just shuffling around and organizing code.

I expect some performance regressions initially, follow-on commits will make
more improvements to that end as the dust settles.
