DRI2: hook up vblank extrapolation to schedule_swap
This patch hooks up swap-scheduling function with
vblank-extrapolation function. Rather than waiting for
fixed time, we calculate exactly how much we should wait
and what we should update target_msc to using
radeon_dri2_extrapolate_msc_delay helper function
and schedule the swap completion using DIX's timer facility.
