Add InitFromFBDev xorg.conf option
Adds a new option that can be specified in xorg.conf - InitFromFBDev.
With this set to a valid fbdev device file the contents of the DRM
scanout buffer will be initialized by bliting from the fbdev device.
This only makes sense when the Xorg -background none parameter is set
on startup, otherwise the background would be overwritten.
The primary use for this feature is to enable a smooth transition
from fbdev to X.
