By attach a driver private struct to each open drm fd. Because we steal the owner_list from drm_sman until things settle, use list_move instead of list_add. This requires to export a drm_sman function temporarily before drm_sman will die for real completely. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
