If we're changing this method signature, could we also update the name to make
the meaning more clear? It is not immediately clear to me whether "adding a
packet to the congestion controller" means
1) adding one incoming RTCP packet (containing feedback about many RTP packets),
2) adding received feedback about one RTP packet, or
3) adding one outgoing RTP packet.

Maybe AddOutgoingPacket, AddPacketToSendTimeHistory or OnPacedPacket? Stefan,
WDYT?

+1, though I'd prefer doing it in a separate CL. Wdys?
