Derek Foreman e4be014f93 compositor: Add an explicit latch point 
Latch is the moment when the compositor considers updates for an upcoming
redraw. Nothing that takes place after an output latches for repaint can
change what will be repainted.

This needs a more explicit treatment now that upcoming transactional
protocols require things to happen immediately after the latch (ie:
when it's too late to change the upcoming render).

Add an explicit latch point, a signal to tap for testing, and some asserts
to make sure nothing can violate the inevitability of the current render
state.

Note that currently latch is tied to repaint such that we only claim to
have latched when a repaint will happen. In a future commit this will lead
to forcing the repaint loop to fire without damage when the fifo protocol
needs something to happen after a latch. This could be an area for
future improvement.
