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.)
