6204adf2ed AEC3: Loosen the echo removal requirements in conservative mode
This CL lowers the margins in the AEC3 conservative mode to increase
the transparency when there are audio buffer issues, and during call
startup.

In particular, this CL adjusts the parameters and thresholds to
-Make the requirements for filter divergence more strict, to minimize
the transparency loss during minor filter divergence.
-Decrease the echo power uncertainty used during initial filter
convergence, to increase transparency after audio buffer issues.
-Deactivate the enforcement of conservative suppressor gain after
audio buffer.

78026754a7 AEC3: Utilize shadow filter output to respond to audio path changes
This CL adds functionality to use the shadow filter output instead
of the main filter output for cases when the former is better than
the latter. One case when that happens is when there have been an
echo path change, either in the acoustic path, in the audio buffers
or due to some active audio processing effects being applied on
the device.

The CL causes less echo leaks, in particular on devices with
active render processing.

b20b93796f AEC3: Refactor the code for analyzing filter convergence
This CL refactors the code in AEC3 that analyzes how
well the adaptive filter performs. The purpose of this
is both to simplify code that is more complex than needed
and also to pave the wave for the upcoming CLs that
softens the echo suppression during doubletalk.

The main changes are that:
-The shadow adaptive filter is now never analyzed. This
turned out to never affect the output in the recordings
it was tested on.
-The convergence analysis was moved to the aec state
code.

The changes are bitexact on all testcases where they
have been tested on.

496cedfe56 AEC3: Reverberation model: Changes on the decay estimation.
In this CL we have introduced changes on the estimation of the decay involved in the exponential modeling of the reverberation. Specifically, the instantaneous ERLE has been tracked and used for adapting faster in the regions when the linear filter is performing well. Furthermore, the adaptation is just perform during render activity.

ec64217e56 AEC3: Simplified suppression gain calculation
This change simplifies the calculation of the suppression gains.
It also contains a new tuning of the suppressor.

The suppressor behavior is tuned by setting echo-to-nearend ratios
for when the suppressor is to be fully transparent and for when to
fully suppress. An echo-to-masker value determines when the signal
is masked by noise. These three values are specified for low and
high frequencies.

2e79d2b398 AEC3: Misadjustment estimator of the linear filter.
In this work the performance of the linear filter is
estimated. The estimation aims at capture situations when the linear
filter is largely over-estimating the echo. In those circumstances,
the linear filter is scaled with the purpose of accelerating its
convergence.

fc63c9e273 AEC3: Allow filter adaptation even though the estimated echo is saturated
This CL removes the constraint that freezes the filter adaptation
whenever the estimated echo or the prediction error is saturated. This
allows for much more rapid filter recovery in cases where the echo path
gain for some reason changes, such as when the analog AGC gain is
adjusted or the loudspeaker volume is changed.
