void silc_fsm_free(void *fsm);

    Free the SILC FSM context that was allocated with silc_fsm_alloc,
    or free the SILC FSM thread context that was allocated with
    silc_fsm_thread_alloc.  This function is used with both SilcFSM
    and SilcFSMThread contexts.

    When freeing FSM, it must not have any active threads.
