* slap_response_play()

* - remove itself from the list, by setting op->o_callback = NULL;
* malloc()'ed callbacks should free themselves from inside the
* sc_response() function.
* - replace itself with another (list of) callback(s), by setting
* op->o_callback = a new (list of) callback(s); in this case, it
* is the callback's responsibility to to append existing subsequent
* callbacks to the end of the list that is passed to the sc_response()
* function.
* - modify the list of subsequent callbacks by modifying the value
* of the sc_next field from inside the sc_response() function; this
* case does not require any handling from inside slap_response_play()
*
* To stop execution of the playlist, the sc_response() function must return
* a value different from SLAP_SC_CONTINUE.
*
* The same applies to slap_cleanup_play(); only, there is no means to stop
* execution of the playlist, since all cleanup functions must be called.
