glx/dri3: Implement LIBGL_SHOW_FPS=1 for DRI3/Present.
v2: Use the UST value provided in the PRESENT_COMPLETE_NOTIFY event
rather than gettimeofday(), which gives us the presentation time
instead of the time when SwapBuffers was called. Suggested by
Keith Packard. This relies on the fact that the X DRI3/Present
implementations use microseconds for UST.
v3: Properly ignore PresentCompleteKindMSCNotify; multiply in 64 bits
(caught by Keith Packard).
