DTX: add data necessary for scheduling
DTXd: to schedule SID repetition we have to know when previous SID was
sent (fn) and if it was UPDATE or FIRST SID (is_update).
DTXu: to properly set Marker bit in outgoing RTP we have to know the
beginning of talkspurt. For codecs without explicit ONSET event we can
do it by setting the flag (ul_sid) upon receiving SID and unsetting it
on speech frames.
