This reverts commit 24eed2735b2135227bcfefbabf34a89f9a5fec99. Reason for revert: Speculative revert: breaks downstream project Original change's description: > Preparation for ReceiveStatisticsProxy lock reduction. > > Update tests to call VideoReceiveStream::GetStats() in the same or at > least similar way it gets called in production (construction thread, > same TQ/thread). > > Mapped out threads and context for ReceiveStatisticsProxy, > VideoQualityObserver and VideoReceiveStream. Added > follow-up TODOs for webrtc:11489. > > One functional change in ReceiveStatisticsProxy is that when sender > side RtcpPacketTypesCounterUpdated calls are made, the counter is > updated asynchronously since the sender calls the method on a different > thread than the receiver. > > Make CallClient::SendTask public to allow tests to run tasks in the > right context. CallClient already does this internally for GetStats. > > Remove 10 sec sleep in StopSendingKeyframeRequestsForInactiveStream. > > Bug: webrtc:11489 > Change-Id: Ib45bfc59d8472e9c5ea556e6ecf38298b8f14921 > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/172847 > Commit-Queue: Tommi <tommi@webrtc.org> > Reviewed-by: Mirko Bonadei <mbonadei@webrtc.org> > Reviewed-by: Magnus Flodman <mflodman@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#31008} TBR=mbonadei@webrtc.org,henrika@webrtc.org,kwiberg@webrtc.org,tommi@webrtc.org,juberti@webrtc.org,mflodman@webrtc.org # Not skipping CQ checks because original CL landed > 1 day ago.
