modesetting: Use atomic modesetting API for pageflip if available
In order to flip between compressed and uncompressed buffers -
something drmModePageFlip explicitly bans us from doing - we need
to port use the atomic modesetting API. It's only 'fake' atomic
though given we still commit for each CRTC separately and
CRTC and connector properties are not set with the atomic API.
The helper functions to retrieve DRM properties have been borrowed
from Weston.
