9249fbf3a6 AEC3: Redesign delay headroom
This change reduces the risk of echo due to noise in the headroom
of the linear filter.

Changes:
- Use shorter delay headroom
- Delay headroom is specified in samples (not blocks)
- No hysteresis limit when delay is reduced

44974e143c AEC3: Adding a correction factor for the Erle estimation that depends on the portion of the filter that is currently in use.
In this CL a more precise estimation of the Erle is introduced. This is done by creating different estimators that are specialized in different regions of the linear filter. An estimation of which regions were used for generating the current echo estimate is performed and used for selecting the right Erle estimator.

877dc89f92 Fix errors in AEC3 JSON parsing
Some issues were surfaced during testing:
 - Config validation clamping silently passed NaNs
 - Config validation only fixed the first out-of-bounds parameter, and
   not any subsequent ones
 - Config validation did not check all values in the config
 - use_stationarity_properties_at_init is misspelled in JSON parsing

These changes are identical to those in this CL:

53e22113fd AEC3: Kill kill-switches
"Perfection is achieved, not when there is nothing more to add,
but when there is nothing left to take away."

This CL removes the following kill-switches from AEC3
- WebRTC-Aec3DownSamplingFactor8KillSwitch
- WebRTC-Aec3NewSuppressionKillSwitch
- WebRTC-Aec3ShadowFilterJumpstartKillSwitch
- WebRTC-Aec3SlowFilterAdaptationKillSwitch
- WebRTC-Aec3SuppressorNearendAveragingKillSwitch

It also removes code paths and configuration parameters that are no
longer in use. The list of kill-switches in the audio processing
fuzzer test is updated.

The change has been tested for bit-exactness.

b02644f2b8 AEC3 transparency improvements through refined echo audibility analysis
This CL increases the transparency in AEC3 during regions of low level
echo. What is done is:
-Low-level echoes are smoothly weighted so as to be deemed less
disturbing.
-The time-domain masking effect of the nearend speech is increased for
all frequencies.
-A separate, even more increased, time-domain masking effect is
introduced for lower frequencies.
-The intra-band masking is reduced to reduce the risk of echo leakage.
-The limiting of maximum gain due to filter-bank dynamics is removed
as the usecase for it could no longer be identified.
