Surfaces are currently managed by the vmwgfx kernel driver, and userspace interacts with surfaces through DRM_VMW_*_SURFACE ioctls. We would like to move to userspace managed surfaces to simplify surface and buffer management across mesa and kernel driver. This change introduces such surfaces, in which the userspace manages surface id's and submits the create and destroy commands. Userspace managed surfaces can be enabled with VMW_SVGA_USERSPACE_SURFACE environment variable. This change is tested with all piglit tests under spec@arb_copy_buffer@* with userspace surfaces turned on.
