This CL adds Resource, ResourceConsumer, ResourceConsumerConfiguration
and ResourceAdaptationProcessor and implements the algorithm outlined
in
https://docs.google.com/presentation/d/13jyqCWNpIa873iKT6yDuB5Q5ma-c0CvxBpX--0tCclY/edit?usp=sharing.
Simply put, if any resource (such as "CPU") is overusing, the most
expensive consumer (e.g. encoded stream) is adapted one step down.
If all resources are underusing, the least expensive consumer is
adapted one step up.
The current resources, consumers and configurations are all fakes;
this CL has no effect on the current adaptation algorithms used in
practise, but it lays down the foundation for future work in this
area.

There is code in socket_adapters.cc that was trying to display UI by
invoking the MessageBoxA API. This causes a linker failure when building
apps for versions of Windows that do not have the MessageBoxA API.
The text message that the socket code tries display also does not seem
right. It references Google Talk and provides a HTTP URI that is
invalid. The message is only in English instead of being localized in
all the languages supported by the app.
I am fixing this by replacing the call to MessageBoxA with a call to
RTC_LOG(LS_ERROR).
I am also attempting to clean up the text of the message by removing
the invalid URL and removing references to Google products. I am trying
to make the logging message more matter-of-fact about what is going on.
As I understand it, the message is displayed when a HTTP proxy sends a
Proxy-Authenticate HTTP response header that specifies an unsupported
authentication scheme. I changed the text of the logging message to
state this.

As of https://webrtc-review.googlesource.com/c/src/+/158899, FEC may be
used on packets with VideoTimingExtension. This may result in creation
of FEC packets that exceed the maximum configured RTP packet size.
This problem occurs most frequently with datagram transports that define a
smaller maximum packet size.

The RWLockWin::Create() function returns NULL on some Windows platforms because it cannot load kernel32.dll. This causes a crash.
RWLockWin tries to load kernel32.dll to check if the Slim Reader/Writer Lock APIs are present in kernel32.dll but on newer Windows platforms, kernel32.dll does not exist and the APIs are exported by kernelbase.dll instead.
The fix is quite simple: There is no need to try to load any DLL to check if the Slim Reader/Writer Lock APIs are present, because these APIs
are always present in all Windows versions since Windows Vista.
I am removing the code that attempts to load kernel32.dll. This prevents the crash on platforms that use kernelbase.dll.
If the WINUWP preprocessor symbol is defined, RWLockWin was already doing the right thing. But this issue is not limited to WINUWP and in
some scenarios, building for WINUWP is not the right solution because it causes other problems. So, my fix is essentially to use the WINUWP
code path for all Windows builds.
The only version of Windows which does not have the Slim Reader/Writer Lock APIs is Windows XP (and older ones, of course.)
However, since the current code does not fall back to an alternative implementation when the Slim Reader/Writer Lock APIs are missing,
WebRTC is already broken on such old versions of Windows.

This removes some code in the AudioDeviceWindowsCore::CoreAudioIsSupported function that was checking that every audio input and output device was functional. There are legitimate cases where some, or all, audio devices may not be accessible, and that was causing CoreAudioIsSupported to return false.
If CoreAudioIsSupported returns false, a subsequent RTC_CHECK call fails, which causes the entire app to exit.
After this change, the CoreAudioIsSupported() function simply checks if the Core Audio APIs are supported and no longer tries to do extra stuff unrelated to checking if the APIs are supported.
Note that Core Audio is actually supported in all versions of Windows after Windows XP. There were log messages in the code saying that if CoreAudioIsSupported() returns false, WebRTC will use the Wave Audio APIs instead. But this is no longer the case. The Wave Audio APIs would only be needed for Windows XP, and this code appears to have already been removed from WebRTC.
It is tempting to simply make CoreAudioIsSupported() do a "return true;" but for now I only removed the part of the logging messages that mentioned the Wave Audio APIs.
I understand that there is a new Audio Device Module (ADM) called WindowsCoreAudio2, which is now recommended for use by apps. Apps are supposed to instantiate WindowsCoreAudio2 and pass it in to WebRTC. When the app supplies its own ADM, CoreAudioIsSupported() does not get invoked, which avoids the bug. To help make it clearer that using WindowsCoreAudio2 is an acceptable solution, I am removing a comment that says that kWindowsCoreAudio2 is "experimental".

This change avoids inadvertent capture of certain system windows (e.g.
the Start menu, other taskbar menus, and notification toasts) when
capturing a specific window on Windows.
It stops using EnumWindows for detection of overlapping windows, because
this API excludes these system windows from its enumeration. Using
FindWindowEx instead enumerates these windows.
The enumeration logic is refactored somewhat because a callback is no
longer necessary.
