commit 5c532d37744ec89927e59c39d82869f12c4e8569

Robustification of the echo suppression behavior during headset usage.

This CL robustifies the echo removal behavior when headsets are used.
In particular it:
-Introduces a secondary, more refined alignment when no alignment can
be found using the delay estimator.
-Changes decision logic for when to use the linear filter output.
-Changes the decision logic for when to be transparent.
-Changes the way that the transparent mode works.
-Makes the nonlinear mode less aggressive.
-Removes the detector for non-audible echoes.
-Makes the attenuation when there are signals with strong narrowband
characteristics more mild in scenarios with low render.

Furthermore the CL:
-Removes the input of external echo leakage information.

I would like to request a merge of this to M66.
It corrects an issue that arose in M64 and/or M65 (not clear which) which in some cases makes the call experience with headsets extremely poor.

The fixing code has been extensively tested on offline data. It has been baking in Canary for a day and during this it has been extensively tested on the devices in our lab.

The merge is very safe as the code it relates to is only active beneath an experimental flag which can be used to deactivate the code in case anything would go wrong. 

This bug requires manual review: Less than 21 days to go before AppStore submit on M66
Please contact the milestone owner if you have questions.

This CL robustifies the echo removal behavior when headsets are used.
In particular it:
-Introduces a secondary, more refined alignment when no alignment can
be found using the delay estimator.
-Changes decision logic for when to use the linear filter output.
-Changes the decision logic for when to be transparent.
-Changes the way that the transparent mode works.
-Makes the nonlinear mode less aggressive.
-Removes the detector for non-audible echoes.
-Makes the attenuation when there are signals with strong narrowband
characteristics more mild in scenarios with low render.

Furthermore the CL:
-Removes the input of external echo leakage information.
