*: embrace new generic settings paradigm

This should probably be split into multiple commits, but
for simplicity sake it's all cut over at once.

drm_fb.c sees major changes, migrating the remaining drm-specific bits
from drmsetup into it, behind the settings API.

rototiller.c sees a bunch of scaffolding surrounding the settings API
and wiring it up into the commandline handling and renderers and video
backends.

fb.[ch] see minor changes as settings get plumbed to the backend

drmsetup.[ch] goes bye bye
