640a65bf96 gst: don't use volatile to mean atomic
volatile is not sufficient to provide atomic guarantees and real atomics
should be used instead.  GCC 11 has started warning about using volatile
with atomic operations.

8d1a79e520 wasapi2device: Make wasapi2 device distinguishable from wasapi device
Both wasapi2 and wasapi plugins use WASAPI API. So "device.api=wasapi"
would make sense for the wasapi2 plugin as well. But people would be
confused by the identical "device.api=wasapi" property if intended
plugin is wasapi, not wasapi2. This change will make them distinguishable
by using "device.api" device property.

be0df31b15 wasapi2: Ensure unmute when opening audio client
ISimpleAudioVolume::SetMute() status seems to be preserved even
after process is terminated. In order to start audio client with
unmuted state, always disable mute when opening audio client.

Disallow getting dispatcher pointer, since it doesn't seem to be useful
and might not be safe.

9e56d20279 wasapi2: Activate device asynchronously if required
In case of UWP, documentation from MS is saying that
ActivateAudioInterfaceAsync() method should be called from UI thread.
And the resulting callback might not happen until user interaction
has been made.
So we cannot wait the activation result on constructed() method.
and therefore we should return gst_wasapi2_client_new()
immediately without waiting the result if wasapi2 elements are
running on UWP application.
In addition to async operation fix, this commit includes COM object
reference counting issue around ActivateAudioInterfaceAsync() call.

c1093e3481 plugins: Use g_win32_error_message for HRESULT to string conversion
We don't need to duplicate a method for HRESULT error code to string
conversion. This patch is intended to
* Remove duplicated code
* Ensure FormatMessageW (Unicode version) and avoid FormatMessageA
  (ANSI version), as the ANSI format is not portable at all.
  Note that if "UNICODE" is not defined, FormatMessageA will be aliased
  as FormatMessage by default.

a6a4267c7b wasapi2: Add device provider implementation
Similar to device provider implementation of wasapi plugin,
this implementation supports only static probing.
But we can implement runtime device add/remove/update
monitoring using DeviceWatcher interface later.

See https://docs.microsoft.com/en-us/uwp/api/windows.devices.enumeration.devicewatcher

2778457678 wasapi2: Introduce new WASAPI plugin
Add a new wasapi implementation mainly to support UWP application.
Basically the core logic of this plugin is almost identical to
existing wasapi plugin, but main target is Windows 10 (+ UWP).
Since this plugin uses WinRT APIs, this plugin most likely might not
work Windows 8 or lower.

Compared with existing wasapi plugin, additional features of this plugin are
* Fully compatible with both Windows 10 desktop and UWP application
* Supports automatic stream routing (auto fallback when device was removed)
* Support device level mute/volume control

But some features of existing wasapi plugin are not implemented
in this plugin yet
* Exclusive streaming mode is not supported
* Loopback feature is not implemented
* Cross-compile is not possible with current mingw toolchain
  (meaning that MSVC and Windows 10 SDK are required to build this plugin)
