File members.cpp: implement the reallocation mechanism (e.g., when the number of ssrcs per collision list goes up to 2, make the size approx. four times bigger (0.5 ssrcs per list now. when the number of ssrcs per list goes down to 0.5, decrease four times. Do not use 2 or 0.5, but `2 + something' and `0.5 - somehting'). Always jumping between prime numbers -> provide a table from 7 to many.
Class Participant: implement reference counting from sources, so that when a source is destroyed, we know if the Participant should be destroyed.
Global QueueRTCPManager::computeRTCPInterval (): make it more flexible as recommended in the draft. For now, we have setMinRTCPInterval.
Global QueueRTCPManager::expireSSRCs (): implement it. It may be dangerous and anyway should be optional.
