Prior to this change, the SimulcastEncoderAdapter would destroy and create
encoders whenever it is being reinitialized. After this change, the
SimulcastEncoderAdapter will cache the already allocated encoders, and reuse
them after reinitialization.
This change will help in reducing the number of PictureID "jumps" that have
been seen around encoder reinitialization.

Since the RtpStreamId and RepairedRtpStreamId extensions can have variable
length, it makes no sense for them to have a constant valueSize field.
The header length calculation in RtpHeaderExtensionMap needed to be changed
for this because it previously worked with the assumption that all header
types have a constant size. Now it's the caller's job to specify the length
of the extensions that it might use.

This small piece of logic is duplicated in DxgiDuplicatorController,
DxgiAdapterDuplicator and desktop_configuration.mm. Meanwhile, the
implementation in desktop_configuration.mm is not safe. So I think a function in
DesktopRect to cover the requirement could be more efficient and safer.

This CL changes the updating of a loop index from using the modulus
operator to using a conditional, avoiding the divisions done in the
modulus operator which had a measurable impact on mpbile
platforms.
Additionally, there is a similar removal of another modulus operator, but the impact of that should be negligible.

This header was not tracked by a GN target and in the discussion on

without creating a stub header in webrtc/system_wrappers.

This CL moves the residual echo detector to reside outside of
the band-scheme in APM. The benefit of this is that the
residual echo detector will then no longer enforce the
band-splitting to be used when it is the only active component
inside APM.
This CL also introduces diagnostic dumping of data inside the
residual echo detector.

The audio mixer has a subcomponent called FrameCombiner, which uses an
AudioProcessing instance as a limiter. The limiter smoothly increases
the volume to avoid causing clipping.
The limiter was created in a default configuration causing the
ResidualEchoDetector submodule of AudioProcessing to be
activated. That submodule operates in the band-split domain (see
AudioProcessingImpl::ApmSubmoduleStates::RenderMultiBandSubModulesActive()).
There is a goal to remove the (expensive and unnecessary)
band-splitting from AudioMixer. This change helps accomplish that. (It
can't be done yet, because the actual limiter sub-component of APM
also operates in the band-split domain).

RequestPlayoutData is expecting number of samples per channel in a

RTP packets can be padded with extra data at the end of the payload. The usable
payload length of the packet should then be reduced with the padding length,
since the padding must be discarded. This was not the case; instead, the entire
payload, including padding data, was forwarded to the audio channel and in the
end to the decoder.
A special case of padding is packets which are empty except for the padding.
That is, they carry no usable payload. These packets are sometimes used for
probing the network and were discarded in
RTPReceiverAudio::ParseAudioCodecSpecific. The result is that NetEq never sees
those empty packets, just the holes in the sequence number series; this can
throw off the target buffer calculations.
With this change, the empty (after removing the padding) packets are let through,
all the way down to NetEq, to a new method called NetEq::InsertEmptyPacket. This
method notifies the DelayManager that an empty packet was received.

The residual echo likelihood should report a likelihood between 0.0 and 1.0. Currently it can happen that echo likelihoods > 1.0 are reported. As a temporary mitigation to stop this, this CL enforces a hard maximum of 1.0 for the echo likelihood while we investigate the issue further.

After a Merge operation, the statistics for number of samples
generated using Expand must be corrected, and the correction can in
fact be negative. However, a bug was introduced in
https://codereview.webrtc.org/1230503003 which uses a size_t to
represent the correction, which leads to wrap-around of the negative
value. This is not a problem in itself, since this value is added to
another size_t, with the effect that the desired subtraction happens
anyway.
The actual problem arises if the statistics are polled/reset before a
subtraction happens -- that is, between an Expand and a Merge
operation. This will lead to an actual wrap-around of the stats value,
and large expand_rate (16384) is reported.

The callbacks are used to give the user of the test object the ability
