Revert "Remove APM internal usage of EchoCancellation"

This reverts commit 1a03960e632a04e2ff866f2048cc36146af83e41.

Reason for revert: breaks downstream projects.

Original change's description:
> Remove APM internal usage of EchoCancellation
> 
> This CL:
>  - Changes EchoCancellationImpl to inherit privately from
>    EchoCancellation.
>  - Removes usage of AudioProcessing::echo_cancellation() inside most of
>    the audio processing module and unit tests.
>  - Default-enables metrics collection in AEC2.
> 
> This CL breaks audioproc_f backwards compatibility: It can no longer
> use all recorded settings (drift compensation, suppression level), but
> prints an error message when such settings are encountered.
> 
> Some code in audio_processing_unittest.cc still uses the old interface.
> I'll handle that in a separate change, as it is not as straightforward
> to preserve coverage.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.

Authoritative list of directories that contain the native API header files.
