+Subject: Bug 1376873 - Fix up logging in WebrtcLog.cpp; r=ng
+
+The webrtc::Trace code is removed by this update. We already had support for
+LOG (now RTC_LOG) in WebrtcLog.cpp. This removes the trace code from
+WebRtcLog.cpp and moves the aec logging code from webrtc::Trace to
+rtc::LogMessage.
+
+This also disables logging to stderr in rtc_base/logging.cc. We could disable
+it using the API, but that happens through peerconnection resulting in some
+logging occuring during getusermedia.
+
+The aec logs were testing with --disable-e10s. Rather than trying to
+work around sandboxing, I think it makes more sense to fix Bug 1404982 and
+store the logs in memory for retrieval from about:webrtc.
