Make ioctl wrappers for functions that will be used by the in-kernel API. The following functions are touched: - drm_mode_create_dumb_ioctl() - drm_mode_destroy_dumb_ioctl() - drm_mode_addfb2() - drm_mode_rmfb() - drm_prime_handle_to_fd_ioctl()
drm_mode_addfb2() also gets the ability to override the debug name.
