1a0c4611d7 Fix compilation of rtc_base_objc on iOS when building as part of Chromium.
When building as part of Chromium, webrtc/base/logging.h is overridden
by webrtc_overrides/webrtc/base/logging.h that uses Chromium logging
macros.

The implementation of webrtc/base/objc/RTCFileLogger.{h,mm} however has
dependency on the webrtc implementation of logging as it define a class
that inherits from rtc::LogSink. Since the class does not exists when
the overrides are used, the file fails compilation.

Fixes the compilation for iOS as part of Chromium by not compiling the
file webrtc/base/objc/RTCFileLogger.{h,mm} in that configuration.

001c20dd47 Move logic of gyp_webrtc into gyp_webrtc.py
For historical reasons gyp_webrtc.py was launcher script
for gyp_webrtc and the python logic lived in the
gyp_webrtc.  This change moves python code into the
.py file makes the extension-free gyp_webrtc a launcher
for gyp_webrtc.py.

Other changes:
* Move the code into a main() function.
* Add call to disable GC to save some processing time.
* Set executable permission on gyp_webrtc.py and remove it from
  gyp_webrtc.

Similar Chromium CL: https://codereview.chromium.org/1216863010

Motivation for this change:
* Gets checked with PyLint
* Easy to add unit tests if we add our own functionality.

06176e49e2 Added new VideoFrameBuffer methods Data[YUV]() etc.
Eliminate most uses of the old methods.

To continue on this path, once we agree the new methods make sense,
the next step is to rename cricket::VideoFrame::GetVideoFrameBuffer
--> video_frame_buffer, to match the name in webrtc::VideoFrame (if we
think that name is ok?). And then start updating all code to access
planes via the VideoFrameBuffer, and delete corresponding methods in
both cricket::VideoFrame and webrtc::VideoFrame.

2c8a2964fd Tune QP-based quality thresholds.
Increases measure time for downscale back to 5 seconds, this is required
to not over-react on hand-waving or quick device rotations.

Also increase max thresholds for QP a bit to not overreact when quality
still looks somewhat OK. Min thresholds for H264 seemed very low and are
increased to be sure that we can go back up again. The window is still
quite big with the increased max QP.

Also changes libvpx thresholds to use the same thresholds as the
encoder, they were excessively low before and wouldn't adapt on bad QPs
at all before (but rely on >60% framedropping based on bitrates to go
down).

594a877f2d Cleaned up the EchoSuppression method in the AEC so that it
does not have to use the aec state as an input.

Furthermore, the debug dump output of e_fft was removed as
it is not really used in any analysis scripts.

0332c2db39 Added support in the AEC for refined filter adaptation.
The following algorithmic functionality was added:
-Add support for an exact regressor power to be computed
 which avoids the issue with the updating of the filter
 sometimes being unstable.
-Lowered the fixed step size of the adaptive filter to 0.05
 which significantly reduces the sensitivity of the
 adaptive filter to near-end noise, nonlinearities,
 doubletalk and the unmodelled echo path tail. It also
 reduces the tracking speed of the adaptive filter but the
 chosen value proved to give a sufficient tradeoff for the
 requirements on the adaptive filter.

To allow the new functionality to be selectively applied the following was done:
-A new Config was added for selectively activating the functionality.
-Functionality was added in the audioprocessing  and echocancellationimpl classes
 for passing the activation of the functionality down to the AEC algorithms.

To make the code for the introduction of the functionality clean,
the following refactoring was done:
-The selection of the step size was moved to a single place.
-The constant for the step size of the adaptive filter in extended filter mode was
 made local.
-The state variable storing the step-size was renamed to a more describing name.

When the new functionality is not activated, the changes
have been tested for bitexactness on Linux.

da3a1da9b1 RTCCertificateGenerator added.
This is a new way of generating RTCCertificate objects that is meant
to replace DtlsIdentityStoreInterface and all of its implementations
(clean up work).
It is similar to the identity store in that it generates on the worker
thread and does callback on the signaling thread, but:
- It does not generate identities in the background that you did not
  ask for (preemptive generation made more sense before certificates
  were parameterized, not so much anymore, and ECDSA which will be most
  common takes like <=2 ms to generate).
- As such this code is less complicated than the store's code.
- The API is different, it takes Optional<uint64_t> expires and it
  returns RTCCertificates, not SSLIdentities.
- It supports a blocking version of GenerateCertificate that can be
  called from any thread, necessary for Chrome which can generate
  certificates before the signaling/worker threads have been
  initialized as WebRTC-threads (Chrome can invoke this version on
  the worker thread outside of WebRTC).

This CL does not remove the identity store, only adds the alternative.
Follow-up CLs will start using it, the store will be removed once it
is no longer used anywhere.
