This CL corrects the way that the estimated filter delay is used in
AEC3. In particular
-It uses the filter delay to choose the correct render block in AecState
-It changes the code to reflect that the filter delay is always computed
-It removes part of the code that formerly relied on the filter delay
being an Optional.

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.

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.
