cd8b079afb Increased the allowed API call jitter in AEC3
This CL increases the amount of API call jitter that is allowed in AEC3
without causing resets of AEC3. This increase is now possible, as non-
causal alignments will be detected by the newly imposed delay bound.

96b951c593 Make AEC3 recover more quickly for lost capture data
This CL ensures that AEC3 recovers more quickly when capture data is
lost in such a manner that the echo path, as seen by AEC3, becomes
noncausal due to the AEC3 buffer misalignment caused by the data loss.

The CL adds the assumption of a minimum echo path delay of 5 blocks
and makes the hysteresis in the delay selection one-sided.

5e6685ff35 Robustification of the AEC3 echo removal in the first part of the call
This CL robustifies the echo removal in AEC3 during the initial parts
of a call in two ways:
-By extending the period until which a headset is deemed to be used.
-By increasing the assumed echo path gain for unknown echo paths at
higher frequencies.

2910357621 Transparency improvements in the echo canceller 3
This CL adds two changes:
-Adaptive adjustment of the echo suppression to both cover the cases
when the echo path well covers the room, and when when it does not.
-Identification of the case when the echo is too low to be audible
and adaptive handling of this case in the echo suppression.

This CL loosens the requirement on the API jitter in APM
that can be tolerated without affecting the AEC3 performance.

5d153c76c6 Reland of Added ARM Neon SIMD optimizations for AEC3 (patchset #1 id:1 of https://codereview.webrtc.org/2856113003/ )
Reason for revert:
The original patch set was correct, but the Chromium bug number needed to be corrected.

2ce640fada Fixing sample-rate dependent band-split filter issues in AEC3
This CL ensures that the number of bands
for the render side matches that for the capture side
when AEC3 is active. Without this, there was problems
when the render rate is different from the capture rate.

4b572d048a Correction of the AEC3 underrun behavior and minor other corrections
This CL corrects the behavior during buffer underruns.

Furthermore, it increases the tolerance for API call jitter, and
removes the minimum value for the comfort noise.

86afe9d661 Major updates to the echo removal functionality in AEC3
This CL adds fairly significant changes to the echo removal
functionality, the main ones being.
-More centralized control over the echo removal.
-Updated echo suppression gain behavior.
-Significantly increased usage of the linear adaptive filter.
-New echo removal functionality when the linear filter is not usable.

This CL is chained to the CL https://codereview.webrtc.org/2784023002/

cf02cf13a7 Major AEC3 render pipeline changes
This CL adds major render pipeline changes to the AEC3 code. The reason
for these are that
1) It allows the echo removal unit to receive information about the content
in bands beyond band 0, thereby allowing removal of high-frequency
echoes
2) It allows more controlled handling of the render buffers, allowing proper
buffer behaviour during capture glitches and clock-drift.

Unfortunately, the render pipeline caused a lot of related changes in much
of the rest of the AEC3 files. Most of these are, however, caused by
a change of class name.

Another unfortunate effect of this CL, is that a number of unittest cease to
compile. I chose to temporarily solve that by removing them from the
build using #if/#endif. The reason for that is that those will anyway again
need to be changed in the next review, and doing like this avoids them
having to be reviewed twice.
