This commit adds the vmwgfx driver for the VWware Virtual GPU aka SVGA. The driver is under staging the same as Nouveau and Radeon KMS. Hopefully the 2D ioctls are bug free and don't need changing, so that part of the API should be stable. But there there is a pretty big chance that the 3D API will change in the future.
