The ReportBlockData contains information about a ReportBlock and additional data such as RTT. This will be used for the calculation of RTCRemoteInboundRtpStreamStats, see full picture here: https://webrtc-review.googlesource.com/c/src/+/134107 ReportBlockData is a class version of the previously internal struct RTCPReceiver::ReportBlockWithRtt. - The new name makes sense even if we add more info to it, which will be needed for future metrics. - The new location is modules/rtp_rtcp/include/report_block_data.h. The RTCPReceiver allows obtaining the ReportBlockData in two ways: 1. Using a ReportBlockDataObserver that is notified on receiving a report block. 2. Using the GetLatestReportBlockData(). Both codepaths will be needed; video stats uses observers and audio stats uses polling. Further plumbing will be done in follow-up CLs.
