Now checks the preferred channel configuration and requests implicit channel
upmixing (audio engine extends from 2 to N channels internally) if the
preferred number of channels is larger than two; i.e., initialize the
stream in stereo even if the preferred configuration is multi-channel.
To summarize: with this CL, it is now possible to use e.g. a 7.1 headset
with a native WebRTC client. All internal processing in WebRTC will be in
stereo, and the audio device will be opened up in stereo as well to match
WebRTC. Before this change, we would open up the audio device using 8
channels but that was not supported by WebRTC.

Second round of the new Windows ADM is now ready for review. Main
changes are:
Supports internal (automatic) restart of audio streams when an active
audio stream disconnects (happens when a device is removed).
Adds support for IAudioClient3 and IAudioClient2 for platforms which
supports it (>Win8 and >Win10).
Modifies the threading model to support restart "from the inside" on
the native audio thread.
Adds two new test methods for the ADM to emulate restart events or
stream-switch events.
Adds two new test methods to support rate conversion to ensure that
audio can be tested in loopback even if devices runs at different
sample rates.
Added initial components for low-latency support. Verified that it works
but disabled it with a flag for now.

Summary of what this CL does:
Existing users can keep using the old ADM for Windows as before.
A new ADM for Windows is created and a dedicated factory method is used
to create it. The old way (using AudioDeviceImpl) is not utilized.
The new ADM is based on a structure where most of the "action" takes
place in new AudioInput/AudioOutput implementations. This is inline
with our mobile platforms and also makes it easier to break out common
parts into a base class.
The AudioDevice unittest has always mainly focused on the "Start/Stop"-
parts of the ADM and not the complete ADM interface. This new ADM supports
all tests in AudioDeviceTest and is therefore tested in combination with
the old version. A value-parametrized test us added for Windows builds.
Improved readability, threading model and makes the code easier to maintain.
Uses the previously landed methods in webrtc::webrtc_win::core_audio_utility.

This CL resolves some minor issues related to running ADM unittests on Windows.
It is rather common on Windows that devices can't be opened up in mono mode and
some tests have been hardcoded to use mono and that leads to crashes and/or error
logs. Now, all tests runs in stereo as well.

Specifically, I'm moving
safe_compare.h
safe_conversions.h
safe_minmax.h
They shouldn't be part of the API, and moving them to an appropriate
subdirectory of rtc_base/ is a good way to keep track of that.

Unit test now checks that ADM:Init() works before any test runs.
It means that all tests will be skipped on bots that lack Pulse
support which is as how it worked before this CL as well. But then,
we detected the lack of support by checking that the audio layer had
changed from Pulse to Alsa.
As a consequence, I also decided to inject fake/mock ADMs in more
unit tests. One was actually already injected for other reasons
(see https://codereview.webrtc.org/2997383002/) but it had accidentally
been "reverted" later in combination with other changes.
To summarize: before this change we had a set of unit tests where real
audio was tested but it was not the intention of the test or required.
In addition, some Linux bots (VM:s) did not support PulseAudio and on
them the tests relied on a fallback mechanism to ALSA to work, i.e.,
we had a rather complex dependency on hardware. This dependency has now
been removed and it should result in more stable tests.
