xfree86/modes: Check for non-desktop monitors during PreInit [v2]

Browse Source 
At startup, we want to ignore non-desktop monitors unless we don't
find any desktop monitors. Because there are no DIX RandR resources
allocated, let the driver store this information in a new field in the
xf86Output structure and then use that value to help decide whether to
include an output as part of the default configuration.

v2:
  Suggested-by: Michel Dänzer <michel@daenzer.net>

  Bump XF86_CRTC_VERSION from 7 to 8. This will let out-of-tree
  drivers know whether this field is available.
