Revert of Added first layer of the echo canceller 3 functionality (patchset #13 id:240001 of https://codereview.webrtc.org/2584493002/ )

Reason for revert:
Memcheck buildbot detected memory leaks in the death tests. The code looks fine to me, but please investigate what causes the error and reland.

Original issue's description:
> Added first layer of the echo canceller 3 functionality.
>
> This CL adds the first layer of the echo canceller 3.
> All of the code is as it should, apart from
> block_processor.* which only contains placeholder
> functionality. (Upcoming CLs will add proper
> functionality into those files.)

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. This page is maintained by the Google Chrome team.

Development

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