void silc_fsm_finish(void *fsm);

    Finishes the `fsm'.  This function may be used in case the FSM
    needs to be finished outside FSM states.  Usually FSM is finished
    by returning SILC_FSM_FINISH from the state, but if this is not
    possible this function may be called.  This function is used with
    both SilcFSM and SilcFSMThread contexts.

    If the `fsm' is a machine and it has running threads, the machine
    will fatally fail.  The caller must first finish the threads and
    then the machine.
