This patch implements the new OPTIONS menu which will function in stead
of the old basic RECOVERY menu. The TO_DEV menu is now directly
reachable through the VolUp+VolDown key combo. Cancelling any menu or
changing USB state will immediately drop back to the menuless base
screens (INSERT or NOGOOD).
Also contains some minor clean-up here and there, like decoupling code
from tests a bit more by reducing reliance on global initializers. Code
for the now obsolete RECOVERY menu will be removed in a follow-up patch.

BRANCH=None
