c2ae4c8a37 Allow separate dump sets for the data dumper in APM
This CL allows separate dump sets to be used when dumping internal
APM data using audioproc_f, opening up for reducing the amount of
data to be dumped.

42eef86c4f Remove unused code in APM
- The injection of the AGC2 level estimator into `AgcManagerDirect`
  is not used anymore
- `ExperimentalAgc::enabled_agc2_level_estimator` can also be removed
- 3 ctors of `ExperimentalAgc` are unused
- `AgcManagerDirectStandaloneTest::AgcMinMicLevelExperiment` can be
  split into separate unit tests (better code clarity)

e5f4c6b8d2 Reland "Refactor rtc_base build targets."
This is a reland of 69241a93fb

Fix: The problem was related to NO_MAIN_THREAD_WRAPPING, which
affects https://source.chromium.org/chromium/chromium/src/+/master:third_party/webrtc/rtc_base/thread.cc;l=257-263;drc=7acc2d9fe3a6e3c4d8881d2bdfc9b8968a724cd5.
The original CL didn't attach the definition of the macro
NO_MAIN_THREAD_WRAPPING when building for Chromium (which doesn't have
to be related to //rtc_base anymore but to //rtc_base:threading).

Original change's description:
> Refactor rtc_base build targets.
>
> The "//rtc_base:rtc_base" build target has historically been one of the
> biggest targets in the WebRTC build. Big targets are the main source of
> circular dependencies and non-API types leakage.
>
> This CL is a step forward into splitting "//rtc_base:rtc_base" into
> smaller targets (as originally started in 2018).
>
> The only non-automated changes are (like re-wiring the build system):
> * The creation of //rtc_base/async_resolver.{h,cc} which allows to
>   break a circular dependency (is has been extracted from
>   //rtc_base/net_helpers.{h,cc}).
> * The creation of //rtc_base/internal/default_socket_server.{h,cc} to
>   break another circular dependency.

e8ee462681 RNN VAD: FC layer simplified
The implementations for the fully connected layer can be simlpified by
using `VectorMath:DotProduct()`. In this way, it is also possible to
remove (nearly) duplicated SIMD code, reduce the binary size and more
easily maintain the code.

This CL also forces unoptimized code for the output layer of the VAD,
which is a FC 24x1 layer. A slight improvement of the realtime has
been measured (delta ~ +5x).

4e9c5b592a RNN VAD: GRU layer optimized
Using `VectorMath::DotProduct()` in GatedRecurrentLayer to reuse existing
SIMD optimizations. Results:
- When SSE2/AVX2 is avilable, the GRU layer takes 40% of the unoptimized
  code
- The realtime factor for the VAD improved as follows
  - SSE2: from 570x to 630x
  - AVX2: from 610x to 680x

This CL also improved the GRU layer benchmark by (i) benchmarking a GRU
layer havibng the same size of that used in the VAD and (ii) by prefetching
a long input sequence.

992a96f68e AEC3: Prevent diverging coarse filter from influencing the refined filter
After the refined filter has been determined to perform better than
the coarse filter, and the coefficients of the coarse filters are
overwritten by the ones from the refined filter, at least 100 ms have
to pass before the adaptation of the refined filter is allowed to speed
up due to good coarse filter performance.

This change solves the vicious circle described in webrtc:12265, where
the coarse and refined filters can diverge over time.

This feature can be disabled remotely via a kill-switch. When disabled
the AEC output is bit-exact to before the change.

fd5dadbea9 RNN VAD: use VectorMath::DotProduct() for pitch search
This CL brings a large improvement to the RNN VAD CPU performance
by finally using `VectorMath::DotProduct()` for pitch search.

The realtime factor improved from about 390x to 570x for SSE2
(+180x, 45% faster) and to 610x for AVX2 (+235x, 60% faster).

RNN VAD benchmark results:
```
+-----+-------+------+------+
| run | none* | SSE2 | AVX2 |
+-----+-------+------+------+
|   1 | 393x  | 572x | 618x |
|   2 | 388x  | 568x | 607x |
|   3 | 393x  | 564x | 599x |
+-----+-------+------+------+
```
*: baseline, no SIMD used for pitch search, but SSE2 used for the RNN

Results obtained as follows:
1. Force SSE2 in `DISABLED_RnnVadPerformance` for the RNN part in
   order to measure the baseline correctly:
```
RnnBasedVad rnn_vad({/*sse2=*/true, /*avx2=*/true, /*neon=*/false});
```
2. Run the test:
```
$ ./out/release/modules_unittests \
  --gtest_filter=*RnnVadTest*DISABLED_RnnVadPerformance* \
  --gtest_also_run_disabled_tests --logs
```

01b3e24a83 RNN VAD: VectorMath::DotProduct with AVX2 optimization
This CL adds a new library for the RNN VAD that provides (optimized)
vector math ops. The scheme is the same of the `VectorMath` class of AEC3
to ensure correct builds across different platforms.

253f8369bb AGC2 RNN VAD: safe SIMD optimizations scheme + AVX2 kill switch
In preparation for adding AVX2 code, a safe scheme to support
different SIMD optimizations is added.

Safety features:
- AVX2 kill switch to stop using it even if supported by the
  architecture
- struct indicating the available CPU features propagated from
  AGC2 to each component; in this way
  - better control over the unit tests
  - no need to propagate individual kill switches but just
    set to false features that are turned off

Note that (i) this CL does not change the performance of the RNN VAD
and (ii) no AVX2 optimization is added yet.

The output of GetLinearAecOutput is changed to have the range [-1, 1]
instead of [-2^15, 2^15] to be more similar to other Audio Processing
Module API functions.

The "--linear_aec_output" of audioproc_f has been tested for
bit-exactness.

05f5d636e5 RNN VAD: pitch search optimizations (part 4)
Add inverted lags index to simplify the loop in
`FindBestPitchPeriod48kHz()`. Instead of looping over 294 items,
only loop over the relevant ones (up to 10) by keeping track of
the relevant indexes.

The benchmark has shown a slight improvement (about +6x).

Benchmarked as follows:
```
out/release/modules_unittests \
  --gtest_filter=*RnnVadTest.DISABLED_RnnVadPerformance* \
  --gtest_also_run_disabled_tests --logs
```

Results:

      | baseline             | this CL
------+----------------------+------------------------
run 1 | 22.8319 +/- 1.46554  | 22.1951 +/- 0.747611
      | 389.367x             | 400.539x
------+----------------------+------------------------
run 2 | 22.4286 +/- 0.726449 | 22.2718 +/- 0.963738
      | 396.369x             | 399.16x
------+----------------------+------------------------
run 2 | 22.5688 +/- 0.831341 | 22.4166 +/- 0.953362
      | 393.906x             | 396.581x

This CL also moved `PitchPseudoInterpolationInvLagAutoCorr()`
into `FindBestPitchPeriod48kHz()`.

ea89f2a447 RNN VAD: pitch search optimizations (part 3)
`ComputeSlidingFrameSquareEnergies()` which computes the energy of a
sliding 20 ms frame in the pitch buffer has been switched from backward
to forward.

The benchmark has shown a slight improvement (about +6x).

This change is not bit exact but all the tolerance tests still pass
except for one single case in `RnnVadTest,PitchSearchWithinTolerance`
for which the tolerance has been slightly increased. Note that the pitch
estimation is still bit-exact.

Benchmarked as follows:
```
out/release/modules_unittests \
  --gtest_filter=*RnnVadTest.DISABLED_RnnVadPerformance* \
  --gtest_also_run_disabled_tests --logs
```

9da3e177fd RNN VAD: pitch search optimizations (part 1)
TL;DR this CL improves efficiency and includes several code
readability improvements mainly triggered by the comments to
patch set #10.

Highlights:
- Split `FindBestPitchPeriods()` into 12 and 24 kHz versions
  to hard-code the input size and simplify the 24 kHz version
- Loop in `ComputePitchPeriod48kHz()` (new name for
  `RefinePitchPeriod48kHz()`) removed since the lags for which
  we need to compute the auto correlation are a few
- `ComputePitchGainThreshold()` was only used in unit tests; it's been
  moved into the anon ns and the test removed

This CL makes `ComputePitchPeriod48kHz()` is about 10% faster (measured
with https://webrtc-review.googlesource.com/c/src/+/191320/4/modules/audio_processing/agc2/rnn_vad/pitch_search_internal_unittest.cc).
The realtime factor has improved by about +14%.

Benchmarked as follows:
```
out/release/modules_unittests \
  --gtest_filter=*RnnVadTest.DISABLED_RnnVadPerformance* \
  --gtest_also_run_disabled_tests --logs
```

8cc6695652 Reformat python files checked by pylint (part 1/2).
After recently changing .pylintrc (see [1]) we discovered that
the presubmit check always checks all the python files when just
one python file gets updated.

This CL moves all these files one step closer to what the linter
wants.

Autogenerated with:

# Added all the files under pylint control to ~/Desktop/to-reformat
cat ~/Desktop/to-reformat | xargs sed -i '1i\\'
git cl format --python --full

This is part 1 out of 2. The second part will fix function names and
will not be automated.
