In https://webrtc-review.googlesource.com/c/src/+/173704 the overhead
calculations were made more static, so that "volatile" extensions
(those that are not set on every packet) are ignored. The intent, as
the comments specify, was to ignore RepairedRtpStreamId since that is
only used on RTX packets.
This CL makes us actually count that extension as volatile.

When Chromium displays the selection dialog for screens it gets the thumbnails by calling SelectSource for the first monitor then CaptureFrame, then SelectSource for the next monitor then CaptureFrame, and so on. With 1 or 2 screens this does not show any issues, but with 3 or more screens the program may crash.
The queue of frame buffers is actually just 2 frame buffers that get swapped every time a frame is captured. When you have one monitor both buffers will be sized for it's resolution. When you have two monitor the first buffer is sized for the first monitor and the second buffer for the second monitor. Since the monitors are selected in turn monitors and frame buffers stay matched up and things work fine. With a third monitor the first buffer is sized for the first monitor, but then later reused to capture the third monitor. If the resolution of the third monitor does not match the first we either crash or have extra junk in the frame from when we captured the first monitor.

This CL changes the way that AecDumps are created in APM. Instead
of being injected, they are now created via the API.
This removes the AecDumpFactory from the API surface of APM and
makes the API more explicit.
The CL will be followed by one more CL that deprecates the usage
of the AttachAecDump API also within the audio_processing
and the fuzzer folders.
The CL also moves the aec_dump.* files from the include folder
to the aec_dump folder and changes the build files. The reasons
for this are that
1) The content of aec_dump.h is not really part of the API
surface of APM.
2) Those files anyway needed to be moved to a separate build-
target to avoid a circular build-file dependency caused by
the other changes in this CL

Max encoder bitrate in WebRTC and OpenH264 are different settings. In
WebRTC it is a cap for encoder target bitrate whilst in OpenH264 it is
a peak bitrate. I.e. OpenH264 is allowed to produce bitrate up to
iMaxBitrate for short time interval. That is not what WebRTC expects.

disabled encoders re-initialization on min/max bitrate change. Reinit of
some HW encoders takes hundreds of milliseconds and causes video freeze.
I missed that max bitrate is used by OpenH264. This caused regression
described in webrtc:11543.
This change sets iMaxBitrate=UNSPECIFIED_BIT_RATE (which is the default
value). Settings iMaxBitrate=UNSPECIFIED_BIT_RATE disables the frame
dropping logic based on that parameter. But the encoder still will drop
frames based on buffer fullness, https://source.chromium.org/chromium/chromium/src/+/master:third_party/openh264/src/codec/encoder/core/src/ratectl.cpp;l=806-807

Call is instantiated on what we traditionally call the 'worker thread'
in PeerConnection terms. Call statistics are however gathered, processed
and reported in a number of different ways, which results in a lot of
locking, which is also unpredictable due to the those actions themselves
contending with other parts of the system.
Designating the worker thread as the general owner of the stats, helps
us keeps things regular and avoids loading unrelated task queues/threads
with reporting things like histograms or locking up due to a call to
GetStats().
This is a reland of remaining changes from https://webrtc-review.googlesource.com/c/src/+/172847:
This applies the changes from the above CL to the forked files and
switches call.cc over to using the forked implementation.

This interface has a couple of issues. Primarily for me, it makes it
difficult work with the paced sender as we need to either temporarily
release a lock or force a thread-handover in order to avoid a cyclic
lock order.
For video in particular, its behavior is also falky since header sizes
can vary not only form frame to frame, but from packet to packet within
a frame (e.g. TimingInfo extension is only on the last packet, if set).
On bitrate allocation, the last reported value is picked, leading to
timing issues affecting the bitrate set.
This CL removes the callback interface and instead we simply poll the
RTP module for a packet overhead. This consists of an expected overhead
based on which non-volatile header extensions are registered (so for
instance AbsoluteCaptureTime is disregarded since it's only populated
once per second). The overhead estimation is a little less accurate but
instead simpler and deterministic.

RtpVideoSender now stores fec type and overhead instead of querying the

current bitrate is also now handled just by the VideoFecGenerator
instance, instead of going via RtpVideoSender.
Finally, adds method to query for RtpState in VideoFecGenerator

trouble after moving fec generation.

This CL introduced 2 new macros that affect the WebRTC OBJC API symbols:
- RTC_OBJC_TYPE_PREFIX:
Macro used to prepend a prefix to the API types that are exported with
RTC_OBJC_EXPORT.
Clients can patch the definition of this macro locally and build
WebRTC.framework with their own prefix in case symbol clashing is a
problem.
This macro must only be defined by changing the value in
sdk/objc/base/RTCMacros.h and not on via compiler flag to ensure
it has a unique value.
- RCT_OBJC_TYPE:
Macro used internally to reference API types. Declaring an API type
without using this macro will not include the declared type in the
set of types that will be affected by the configurable
RTC_OBJC_TYPE_PREFIX.

This CL breaks up the CheckQp() operation into several steps managed
by the inner helper class CheckQpTask, making responding to high or
low QP an asynchronous operation. Why? Reconfiguring the stream in
response to QP overuse will in the future be handled on a separate
task queue. See Call-Level Adaptation Processing for more details:
https://docs.google.com/document/d/1ZyC26yOCknrrcYa839ZWLxD6o6Gig5A3lVTh4E41074/edit?usp=sharing
Instead of "bool AdaptDown()" when high QP is reported,
synchronously returning true or false depending on the result of
adaptation, this CL introduces
void QualityScalerQpUsageHandlerInterface::OnReportQpUsageHigh(
rtc::scoped_refptr<QualityScalerQpUsageHandlerCallback>);
Where
QualityScalerQpUsageHandlerCallback::OnQpUsageHandled(
bool clear_qp_samples);
Instructs the QualityScaler whether to clear samples before
checking QP the next time or to increase the frequency of checking
(corresponding to AdaptDown's return value prior to this CL).
QualityScaler no longer using AdaptationObserverInterface, this class
is renamed and moved to overuse_frame_detector.h.
The dependency between CheckQpTasks is made explicit with
CheckQpTask::Result and variables like observed_enough_frames_,
adapt_called_ and adapt_failed_ are moved there and given more
descriptive names.

This CL is functionally a noop but may reduce thread wakupes in some
cases.
In particular, consider a send task scheduled for time T. While waiting
for that, a higher-priority packet than the top of the current queue is
added (e.g. an audio packet), and a send is executed immediately.
After sending, it resets the field indicating that a scheduled task is
expected at time T. It then polls NextSendTime() and schedules a new
task, likely at or very close to T. Causing unnecessary task queue
churn and behavior that is more difficult to reason about.

Today when the pacing debt is cleared, we blindly ask for 50 bytes of
padding, which is above a static magic number for RTX payload padding.
Instead, we should adjust the target size based on the current padding
rate. The old pacer sort-of does this, it allows the budget to grow up
to one process interval (usually 5ms).
This CL makes the dynamic pacer also use a duration as target, by
default 5ms to match old pacer but with a trial to allow tweaking it.
This will be important for good behavior due to

------------ original description --------------
Preparation for ReceiveStatisticsProxy lock reduction.
Update tests to call VideoReceiveStream::GetStats() in the same or at
least similar way it gets called in production (construction thread,
same TQ/thread).
Mapped out threads and context for ReceiveStatisticsProxy,
VideoQualityObserver and VideoReceiveStream. Added
follow-up TODOs for webrtc:11489.
One functional change in ReceiveStatisticsProxy is that when sender
side RtcpPacketTypesCounterUpdated calls are made, the counter is
updated asynchronously since the sender calls the method on a different
thread than the receiver.
Make CallClient::SendTask public to allow tests to run tasks in the
right context. CallClient already does this internally for GetStats.
Remove 10 sec sleep in StopSendingKeyframeRequestsForInactiveStream.
