16ccfdf457 Reland Move fake_audio_device to its own target.
Patchset 1 is patchset #5 id:80001 of https://codereview.webrtc.org/2717983003/
Patchset 2 fix call_perf_test dep on fake_audio_device.

This reverts commit 985371bda999c6db51286586c5850d2ff58f3511.

Original cl description:

Move fake_audio_device to its own target.
The purpose is to make it usefull for test targets that does not need or can use test_common.

For some reason this also triggered override issues in rtp module tests that are fixed in the same cl.

aebc61e3dc Minor cleanups in VideoProcessor.
This CL is broken out from a future "real" CL, that introduces
support for pipelining HW codecs to VideoProcessor. I order to
simplify the reviewing of that CL a bit, some of the cleanups are
split out here.

No functional changes are intended.

1) Improves the handling of the initial echo suppression
before the linear filter is reliable.
2) Improves the handling of echo path changes.

There are also minor bugfixes included.

a8ba195db5 Replace test::FrameGenerator::ChromaGenerator with new FrameGenerator::SquareGenerator The problem with the ChromaGenerator is that the VP8 encoder produce a too low bitrate for each frame. The squaregenerator make the VP8 encoder produce about 600kbit/s at VGA.
SquareGenerator is a FrameGenerator that draws 10 randomly sized and colored
squares. Between each new generated frame, the squares are moved slightly
towards the lower right corner.

It's benign, but the implementation seems to be done to accomodate the
test rather than the other way around, so I'm making the test behave
more like a ProcessThread would.

This CL adds correction of the echo suppressor gain
It contains 2 changes:
-Bounds the upper value for the echo suppression gain
for bin 1 to avoid that the high-pass filter causes the
gain to be high for bin 1, which in turn may impact the
realization of any lower gains for the neighboring bins.
-Bounds the upper values for the echo suppression gains
for the higher bins to avoid any impact of the
external anti-aliasing filters.

8697f9afba Skips the first frame in DxgiDuplicatorController
A bug has been reported to complaint the ScreenCapturerWinDirectx cannot capture
the first frame, which is used in "Report an issue" page.
A simple solution here is to skip the first frame.

This change also removes the friend relationship between
DxgiDuplicatorController / DxgiAdapterDuplicator / DxgiOutputDuplicator, which
is not really necessary.

0f8b403eb5 Introduce a new constructor to PlatformThread.
The new constructor introduces two new changes:

* Support specifying thread priority at construction time.
  - Moving forward, the SetPriority() method will be removed.
* New thread function type.
  - The new type has 'void' as a return type and a polling loop
    inside PlatformThread, is not used.

The old function type is still supported until all places have been moved over.

In this CL, the first steps towards deprecating the old mechanism are taken
by moving parts of the code that were simple to move, over to the new callback
type.

087613c8df Rename AudioMixer factory method.
AudioMixerImpl::CreateWithOutputRateCalculatorAndLimiter(rate_calculator, bool limiter)

was added to create a mixer without the limiter subcomponent. Calling
it "Create with ... *and* limiter" is counterintuitive.

Renamed to simply 'Create'.
