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.

Instead, use the corresponding method on VideoFrameBuffer. In the process,
reduce code duplication in frame comparison functions used in
the test code.
Make FramesEqual use FrameBufsEqual. Make the latter support texture frames.
The cl also refactors VideoFrame::CopyFrame to use I420Buffer::Copy. This
has possibly undesired side effects of never reusing the frame buffer of
the destination frame, and producing a frame buffer which may use different
stride than the source frame.

If a very large frame is sent (high res slide change) when the available
send bitrate is very low, the it might take many seconds before any new
frames are emitted as the accrued debt will take time to pay off.
Add a bailout, so that if a frame hasn't been sent for 2 seconds, cancel
the debt immediately, even if the target bitrate is then exceeded.

Previously screen capturers were initialized when they are created.
This means that in the CRD host they were initialized on the thread
that's different from the thread on which they are used. Because of this
on Linux the host was using XErrorTrap() on two different threads and
this is not supported. Now ScreenCapturer implementations always
initialize themselves on the thread on which Start() is called.
Also added ThreadChecker to make sure the capturers are always called
from the same thread.

With the current AEC algorithm, the divergence of the echo cancelling linear filter is a strong signal of non-transparency. During double talk, it can result in a ducking artifacts.
In this CL, a metric that tells the fraction of filter divergence is added. This can measure the severity of non-transparency.

With this change, the return value from NetEq::GetPlayoutTimestamp is
empty if the latest call to NetEq::GetAudio resulted in comfort noise
(codec-internal or external) being played out. This is because the
playout timestamp is not updated during CNG, and can therefore not be
trusted.

The reason for the revert is that for some scenarios
that CL causes problems in the coherence estimate used
in the AEC, which in turn causes echo leakage.
The reason for not reverting the actual CL is that
it would cause subsequent CLs to be reverted as well.
Therefore the choice was made to in this CK
instead revert the effects of that CL.
With the changes in this CL, the behavior is bitexact
to what it was before the CL mentioned above.
