configuration, inputs and outputs over a period of time. It is activated by AudioProcessing::StartRecording. The data is stored in binary protobuf format in a specified file. The file IO is, as of this CL, done from the real-time audio thread. This CL contains an interface for AecDump, a new APM submodule that will handle the recordings. Calls to the new interface from the AudioProcessingModule are added. These calls have no effect, and for a short while, audio_processing_impl.cc will contain two copies of recording calls. The original calls are guarded by the WEBRTC_AUDIOPROC_DEBUG_DUMP preprocessor define. They still have an effect, while the new ones do not. In the following CLs, the old recording calls will be removed, and an implementation of AecDump added. The reasons for the refactoring is to move file IO operations from the real-time audio thread, to add a top-level low-priority task queue for logging tasks like this, to simplify and modularize audio_processing_impl.cc and remove some of the preprocessor directives. These goals will be archived by the upcoming CLs. The implementation is in https://codereview.webrtc.org/2865113002.
