282028e753 rtpsession: when we schedule BYE, only deal with BYE sources 
When we are doing the RTCP timeout to schedule BYE packets, don't
generate RTCP for all sources but only for the sources marked as BYE.

bec9c04ea0 session: ignore RTCP packets for the BYE sources 
When we are scheduling BYE packets, ignore all RTCP for the sources that
are scheduling a BYE packet. Other sources that are not scheduling BYE
should continue receiving RTCP packets as usual.

b81b2efa3e rtpjitterbuffer: fix crash when do-retransmission=true and a lot of buffers are lost 
The problem here was that the jitterbuffer lock was unlocked to push
the event, but that caused another thread to remove the timer currently
being processed, probably because the amount of rtx events
(and therefore timers) was getting too high. The solution is to
unlock and push the event only after timer processing has finished.

d4892859d4 jitterbuffer: fix race in flush-start/flush-stop

00056965e8 rtpjitterbuffer: fix race when updating the next_seqnum 
If we were not waiting for the missing seqnum when we insert the lost packet
event in the jitterbuffer, we end up not updating the next_seqnum and wait
forever for the lost packets to arrive. Instead, keep track of the amount of
packets contained by the jitterbuffer item and update the next expected
seqnum only after pushing the buffer/event. This makes sure we correctly handle
GAPS in the sequence numbers.
