We're moving to an RtcEventLog interface that accepts std::unique_ptr<EventLog> and stores the event for encoding when encoding becomes necessary, rather than before. This will be useful while we maintain the legacy (current) encoding alongside the new encoding on which we're working. This CL adds the internals of RtcEvent's subclasses - the actual data that they keep. (Work on this was broken down into several CLs in order to make reviewing easier.)
