A new optional parameter "-d msecs" allows to specify a
delay before the surface attach/damage/commit to shift
the point in time when a surface update is committed.
This allows to test how different client timings interact
with the compositors repaint timing.

v2: Clarify the intent, doing a delay in window_create_feedback()
is a bit surprising. Use nanosleep() instead of clock_nanosleep(),
which may not support the chosen presentation clock.
