This change removes the (unused) ability of EchoRemover overriding the delay of the RenderDelayController. The change is tested for bit-exactness. Bug: webrtc:8671 Change-Id: I188ef740f1437de64ffe236d07a7dcd4128192c2 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/130518 Commit-Queue: Gustaf Ullberg <gustaf@webrtc.org> Reviewed-by: Per Åhgren <peah@webrtc.org> Cr-Commit-Position: refs/heads/master@{#27414}
