bd83b914c3 Separate AEC3 config from AudioProcessing::Config.
The struct containing the config for AEC3 is removed from
AudioProcessing::Config and is put in a new struct called
EchoCanceller3Config.

AEC3 should no longer be activated through
AudioProcessing::ApplyConfig. Instead an EchoCanceller3Factory
can be injected at AudioProcessing creation.

0743814fb8 aec3: Use fabsf() instead of std::abs() for floats.
We are using <math.h>, not <cmath>. While the latter defines additional
overloads for abs(), including abs(float), they are not guaranteed to be
available in <math.h>.

libc++ ships its own math.h with the additional overloads, and libstdc++ (v6
or later) has a math.h that includes <cmath>, but this is not always
expected to work: for example, GCC 5.x's libstdc++ does not have these
additional overloads and causes the build to fail.

Just use fabsf() from the C standard library directly, as it achieves the
same thing in a more portable fashion.

40659c3eaf Corrected and robustified the detection of the delay in the AEC3 filter
This CL changes the filter delay detection to rely on the largest peak
while the correctness of the filter is changed to be based on the
performance achieved by the filter.

1f33a37565 AEC3 tunings to increase the transparency
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.

930021d465 Eliminating the risk of sustained echo during capture data loss in AEC3.
This CL adds an offset to the delay estimation used in AEC3 for 
determining the alignment between the render and capture signals.
This ensures that there is no possibility for the capture loss to 
cause the delay estimation to miss aligning the signals.

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.
