Historically our device headers have been forked versions of the
internal device headers, this has made maintaining them a bit
of a burden. To fix the situation, going forward, the device headers
will be verbatim copies of the internal headers.
To do that the driver code has to be adapted to use pristine
device headers. This will make future update to the device
headers trivial and automatic.

In cases where the dirty linear memory range spans multiple sample sheets
in a surface, the dirty surface region is incorrectly computed.
To do this correctly and in an optimized fashion we would have to compute
the dirty region of each sample sheet and compute the union of those
regions.
But assuming that cpu writing to a multisample surface is rather a corner
case than a common case, just set the dirty region to the full surface.
This fixes OpenGL piglit errors with SVGA_FORCE_COHERENT=1
and the piglit test:
fbo-depthstencil blit default_fb -samples=2 -auto

Add the callbacks necessary to implement emulated coherent memory for
surfaces. Add a flag to the gb_surface_create ioctl to indicate that
surface memory should be coherent.
Also bump the drm minor version to signal the availability of coherent
surfaces.
