This extension provides fences and frame count information to direct
display contexts. It uses new kernel ioctls to provide 64-bits of
vblank sequence and nanosecond resolution.
v2: Remove DRM_CRTC_SEQUENCE_FIRST_PIXEL_OUT flag. This has
been removed from the proposed kernel API.
Add NULL parameter to drmCrtcQueueSequence ioctl as we
don't care what sequence the event was actually queued to.
v3: Adapt to pthread clock switch to MONOTONIC
v4: Add support for anv
