    netinet: Remove IP(V6)_BINDMULTI

    This option was added in commit 0a100a6f1ee5 but was never completed.
    In particular, there is no logic to map flowids to different listening
    sockets, so it accomplishes basically the same thing as SO_REUSEPORT.
    Meanwhile, we've since added SO_REUSEPORT_LB, which at least tries to
    balance among listening sockets using a hash of the 4-tuple and some
    optional NUMA policy.

    The option was never documented or completed, and an exp-run revealed
    nothing using it in the ports tree.  Moreover, it complicates the
    already very complicated in_pcbbind_setup(), and the checking in
    in_pcbbind_check_bindmulti() is insufficient.  So, let's remove it.
