This is initial change adding support for DRIVER_GEM to vmwgfx. vmwgfx was written before GEM and has always used TTM. Over the years the TTM buffers started inherting from GEM objects but vmwgfx never implemented GEM making it quite awkward. We were directly setting variables in GEM objects to not make DRM crash. This change brings vmwgfx inline with other DRM drivers and allows us to use a lot of DRM helpers which have depended on drivers with GEM support. Due to historical reasons vmwgfx splits the idea of a buffer and surface which makes it a littly tricky since either one can be used in most of our ioctl's which take user space handles. For now our BO's are GEM objects and our surfaces are opaque objects which are backed by GEM objects. In the future I'd like to combine those into a single BO but we don't want to break any of our existing ioctl's so it will take time to do it in a non-destructive way.
