New file structure and targets: rtc_stats_api webrtc/api/stats/rtcstats.h webrtc/api/stats/rtcstats_objects.h webrtc/api/stats/rtcstatsreport.h rtc_stats (dep on rtc_stats_api) webrtc/stats/rtcstats.cc webrtc/stats/rtcstats_objects.cc webrtc/stats/rtcstatsreport.cc libjingle_peerconnection (dep on rtc_stats) webrtc/api/rtcstatscollector.cc webrtc/api/rtcstatscollector.h Placing rtc_stats_api headers in this separate target instead of libjingle_peerconnection avoids a circular dependency libjingle_peerconnection -> rtc_stats -> libjingle_peerconnection Code changes: PeerConnectionInterface::GetStats(RTCStatsCollectorCallback*) added for the new stats collection API. Implemented by PeerConnection. BUG=chromium:627816 Review-Url: https://codereview.webrtc.org/2331373004 Cr-Commit-Position: refs/heads/master@{#14246}
