    Start to untangle the ifnet ioctls mess.

    Add ifnet functions, if_mcast_op(), if_flags_set(), and if_addr_init()
    for adding/deleting multicast addresses, modifying the if_flags,
    and initializing local/remote addresses.  Make ifpromisc() use
    if_flags_set().  Protocols and network drivers should use these
    instead of ifp->if_ioctl() calls.  Subsequent commits will
    replace ifp->if_ioctl(SIOCADDMULTI| SIOCDELMULTI| SIOCSIFDSTADDR|
    SIOCINITIFADDR| SIOCSIFFLAGS) calls with calls to the new functions.

    Use a mutex(9) to synchronize ifp->if_ioctl() calls originating in
    userland.  Also synchronize ifp->if_ioctl() calls with ifnet detachment
    and reclamation.
