    Fix some screw cases in cmsg file descriptor passing.

    - Don't leave garbage in the control buffer if allocating file
    descriptors fails in unp_externalize.

    - Scrub the space between CMSG_LEN and CMSG_SPACE to avoid kernel
    memory disclosure in unp_externalize.

    - Don't read past cmsg_len when closing file descriptors that
    couldn't get delivered, in free_rights.
