[Patch 3/5 v2] Improve wayland-drm to wayland-gbm to act as generic buffer manager for wayland

it is similar to gbm_bo_create_from_egl_image(), and extends the usage
to share drm/gbm buffers basing on native handle instead of
EGLImage/__DRIimage; which is convenient for vaapi driver.
we can see that weston has already shared EGLImage(for texture) with
client in weston_surface_attach() basing on wl_buffer
my patch set just extends the buffer sharing to include video driver.
krh, could you give some comments?
