This patch adds a vblank synced pageflip ioctl for to the modesetting
family of ioctls. The ioctl takes a crtc and an fb and schedules a
pageflip to the new fb at the next coming vertical blank event. This
feature lets userspace implement tear-free updating of the screen

If userspace passes an object list with the same object appearing more
than once, we end up hitting the BUG_ON() in
i915_gem_object_set_to_gpu_domain() as it gets called a second time
for the same object.

This fixes a potential dead lock similar to the one where we copy the
new buffer offsets back to userspace, fixed in
0e2f967303023f7f82a0963b7f7f3980d4c08f20. In this case the lock order
violation occurs when i915_emit_box() copies the cliprects from
userspace from i915_d
