Fixes need to clean up the mess I made with the mesa merge. This code

    allows the mesa drivers to use a single definition of the DRM
    sarea/IOCTLS located in the drm driver directory. Adjustments were made
    to the 2D drivers to not include these changes. Changes to the mesa
    copy of DRM were copied to the DRI copy. XFree86 bug: Reported by:
