How does this RtcpPacket differ from RTCPPacket? Is this part of a new
refactoring to use the new RtcpPacket class?

This is the base class for the shiny new RtcpPacket classes asapersson@
introduced. Currently they're only used on the send side, but I think we should
work towards using them on the receive side as well..
