This CL changes the tuning of AEC3 to increase the transparency.
In particular:
-The present parameters are re-tuned.
-An oversuppression factor is added in the newly added soft-knee in
the NLP gain. The purpose of this is to avoid fluctuations in the
residual echo.
-The dynamics of the computed gain are bounded to ensure that the
specified gain characteristics are realizable without echo leakage.
This also adds robustness against echo leakage in frequency regions
that are poorly estimated.
This change was needed to avoid echo leakage from the above
tunings.

This CL separates the NLP gain computation for the different variants
of echo estimation. This simplifies the setting of tuning
parameters, with resulting transparency improvements and increased
echo removal performance.

This CL adds the ability to set a default echo path delay to use
in AEC3 when there is prior knowledge about the delay in the echo
path.

This CL adds some general AEC3 transparency improvements.
Specifically:
-A minimum for how the nearend is masking echo is added.
-A temporal smoothing constant is increased to increase the transparency.
-Parameters are surfaced to the parameter config struct.

This CL adds an interface for a generic PostProcessing module that
is optionally added to the APM at construction time.
(Parenthetically this CL also adds a missing lock check to
InitializeGainController2.)

Now that we have moved WebRTC from src/webrtc to src/, common_types.h
and typedefs.h are triggering a cpplint error.
The cpplint complaint is:
Include the directory when naming .h files [build/include] [4]
This CL disables the error but we have to remove these two headers
from the root directory.
