This CL centralizes the render buffering in AEC3 so that all render buffers are updated and synchronized/aligned with the render alignment buffer. Bug: webrtc:8597, chromium:790905 Change-Id: I8a94e5c1f27316b6100b420eec9652ea31c1a91d Reviewed-on: https://webrtc-review.googlesource.com/25680 Commit-Queue: Per Åhgren <peah@webrtc.org> Reviewed-by: Gustaf Ullberg <gustaf@webrtc.org> Cr-Commit-Position: refs/heads/master@{#20989}
