28641e3145 rtpjitterbuffer: add type to the item 
So that the upper layer can know what data is contained in the item.

39a2ba669d rtpjitterbuffer: use structure to hold packet information 
Make the jitterbuffer operate on a structure containing all the packet
information. This avoids mapping the buffer multiple times just to get the RTP
information. It will also make it possible to store other miniobjects such as
events later.

1760817005 rtpjitterbuffer: update expected timer when possible 
When we receive a packet and we have some missing packets, we can update their
estimated arrival times based on the timestamp difference.

fdc1ed1680 rtpjitterbuffer: fix order of timeout events 
Improve the order of the timeout events, if there are timers with the same
timeout, we want to trigger the lowest seqnum first. For this we need to loop
over the complete array of timers to find the best one before triggering the
timeout.

0b1a7edfea rtpjitterbuffer: send lost event before signaling next buffer 
First send the lost event, then update the next_seqnum counter and then
send the signal to the pushing thread that it can retry to push a buffer. This
avoids pushing out buffers before the lost event is pushed.

5051f51f0a jitterbuffer: configure clock-rate on jitterbuffer 
Add a get and setter to configure the clock-rate in the jitterbuffer instead of
passing it as an argument to the insert method.

6f4deab298 rtpjitterbuffer: stop the timer thread 
The timeout code could release the lock so we need to check if we are allowed to
wait for the clock some more.

5dc207948c rtpjitterbuffer: improve flush and shutdown 
There is no need to unschedule the timer in flush-start, flush-stop will remove
the timers and unschedule.
Unschedule the current timer before attempting to join the timer thread.

a512cc2d3c rtpjitterbuffer: set correct expected time 
When we already have a timer for a packet, skip it but don't forget to adjust
the dts to the expected dts of the next packet.

fd6c57cf10 rtpjitterbuffer: keep delay as a separate variable in timer 
Keep a separate delay in the timer so that we still know the original timestamp
of the packet that this timer refers to. We can then place the correct
running-time in the Retransmission event.

6bb2626498 rtpjitterbuffer: reevaluate the current timer after timeout 
When we trigger the timeout logic of a timer, reevaluate it because it is
possible that it still has the lowest timeout.

65606a25bf rtpjitterbuffer: init packet spacing on first buffer 
Already init the packet spacing variables on the first buffer so that we can
calculate the spacing on the second buffer already.

f2efdf28f5 rtpjitterbuffer: push the lost event from the timer thread 
Instead of pushing the lost event from the chain function, schedule a timeout
that will push the lost event from the timer thread. This avoid blocking the
upstream thread while we push and sync the event.

duration.

ac3bb3acf6 rtpjitterbuffer: handle large gaps with one lost event 
When we have a large number of missing packets, generate one lost event for all
the packets that have no chance of being pushed out in time.
Fix and activate unit test for large gaps.

047021c443 jitterbuffer: simplify the timeout code 
Keep track of the current time in the timeout loop.
Loop over all timers and trigger all the expired ones, we can do this in the
same loop that selects the new best timer.

fa1ef3328b jitterbuffer: rearrange timer update code 
Also update the timers when retransmission is disabled. We need to
do this because when we added LOST timers when we detected missing packets and
we need to remove those timers when the packet finally arrives.

downstream streaming thread that might block at any time.

transform it back to a buffer timestamp before pushing out the buffer.

f1106cde66 session: only update next check time when reconsidering 
Don't update the next RTCP check time in all cases but only when we
reconsidered. This avoids delaying sending a full RTCP packet when we
are doing early feedback.
