77846d35c6 rtpjitterbuffer: refactor jitterbuffer
Refactor the jitterbuffer code. Make separate function for peeking a buffer,
pushing the next buffer, waiting for timeouts and handling the timeouts.

The main loop now tries to push as many buffers as it can until it runs out of
buffers or when it detects a seqnum discont. Then it will wait for some event to
happen before attempting to push more buffers.

Make methods to register timeouts in an array. These timeouts are registered
when we detect a missing packet, sync for the first packet or when we find an
estimation for the end-of-stream.

This greatly simplifies and clarifies the code and also makes it possible to
register more complicated timeout schemes later.

02359f9219 session: don't make buffer writable prematurely
There is no reason to make the SR buffer writable at this point. This is better
delayed until needed.

e0abd2e9b5 session: handle partial RTCP report blocks
When we have more SSRCs to report than what fit in an RTCP packet, use a
generation counter to make sure all of them end up in a packet eventually.

95429f1d4b rtpbin: added custom downstream sync event
rtpbin can now send a custom in-band downstream event which informs
downstream that the bin has received an RTCP SR packet. This is useful
for applications which want to drop the initial unsynchronized received
RTP packets.

RTP packet but remember and use it to signal sync once we get the
RTP packet.
