This CL moves/removes all code from the AudioBuffer that: -Is not directly handling audio data (e.g., keytaps, VAD descisions). -Is caching aggregated versions of the rest of the audio data. -Is not used (or only used in testing) Bug: webrtc:10882 Change-Id: I737deb3f692748eff30f46ad806b2c6f6292802c Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/149072 Reviewed-by: Gustaf Ullberg <gustaf@webrtc.org> Commit-Queue: Per Åhgren <peah@webrtc.org> Cr-Commit-Position: refs/heads/master@{#28866}
