The blk_register_buf() API is an optimization hint that allows some block drivers to avoid I/O buffer housekeeping or bounce buffers. Add an -r option to register the I/O buffer so that qemu-io can be used to test the blk_register_buf() API. The next commit will add a test that uses the new option. Reviewed-by:
