daemon: rtcp muxing
Issue generated from Tuleap's migration script. Originally submitted by: Guillaume Roguez (guillaume)
Using RTCP muxing permit to decrease the ICE overhead due to usage of dedicated RTCP channel (one per RTP channel).
In your case it's 2 sockets removed.
The RTCP flow is very limited compared to RTP flow and we're not impacted by RTP payload type restrictions in such situation.
