Reason for revert: Can reland it if backwards compatible API is kept. Original issue's description: > Revert of Enable cpplint and fix cpplint errors in webrtc/*audio (patchset #4 id:180001 of https://codereview.webrtc.org/2683033004/ ) > > Reason for revert: > The API change in audio/utility/audio_frame_operations.h caused breakage. Need to keep backward-compatible API. > > Original issue's description: > > Enable cpplint and fix cpplint errors in webrtc/*audio > > > > Change usage accordingly throughout the codebase > > > > BUG=webrtc:5268 > > > > TESTED=Fixed issues reported by: > > find webrtc/*audio -type f -name *.cc -o -name *.h | xargs cpplint.py > > > > Review-Url: https://codereview.webrtc.org/2683033004 > > Cr-Commit-Position: refs/heads/master@{#17133} > > Committed:aebe55ca6c> > TBR=henrika@webrtc.org,henrik.lundin@webrtc.org,kwiberg@webrtc.org > # Skipping CQ checks because original CL landed less than 1 days ago. > NOPRESUBMIT=true > NOTREECHECKS=true > NOTRY=true > BUG=webrtc:5268 > > Review-Url: https://codereview.webrtc.org/2739143002 > Cr-Commit-Position: refs/heads/master@{#17138} > Committed:e47c1d3ca1TBR=henrika@webrtc.org,henrik.lundin@webrtc.org,kwiberg@webrtc.org # Skipping CQ checks because original CL landed less than 1 days ago.
