Reason for revert: Reverting, because it turns out that third-party code was using webrtc::FilePlayer. I'm not at all sure that this is something WebRTC ought to be exporting, but since we did export it, we have to live with it for now. Original issue's description: > Move FilePlayer and FileRecorder to Voice Engine > > Because Voice Engine was the only user. > > (This has been landed twice before, as > https://codereview.webrtc.org/2037623002 and > https://codereview.webrtc.org/2240163002. Third time's a charm!) > > NOPRESUBMIT=True > TBR=kjellander@webrtc.org > > Committed: https://crrev.com/427ce3d86f6328dc994f84a15c28bb7bfbaa46ef > Cr-Commit-Position: refs/heads/master@{#13777} TBR= # Skipping CQ checks because original CL landed less than 1 days ago.
