The RtpDemuxer uses a number of maps, all of which can be made unordered as they map SSRCs/MIDs/payload types/RSIDs etc - all of which have no inherent ordering. In busy media servers, the std::map operations can use ~0.5% CPU. After this commit has landed, it will be evaluated and if it doesn't live up to expected savings, it will be reverted.
