Some people need to avoid inclusion of GPL code for their use cases and thus
get easily spooked by GPL license headers. This code is actually licensed
under different licenses, only one of which is GPL, and it's already possible
to just upgrade from LGPL to GPL anyway so having the GPL listed explicitly
as one of the choices doesn't really add anything. So remove GPL from the list
and also add SPDX license identifiers while we're at it.

Adding IMMDeviceEnumerator::RegisterEndpointNotificationCallback
in order to support device monitoring.
On OnDeviceAdded(), OnDeviceRemoved(), and OnDefaultDeviceChanged()
callback, wasapi device provider implementation will enumerate
devices again and will notify newly added and removed device
via GstDeviceProvider API.

As a bonus point, this IMMDeviceEnumerator abstraction object
will spawn a dedicated internal COM thread, so various COM thread
related issues of WASAPI plugin can be resolved by this commit.

In ALSA, there is possible temporary failures that may require a retry,
though in certain situation, this may leak to the write() function
holding on a lock forever preventing the pipeline from going to pause
or stop. Fix this by shortly dropping the lock between retries.

This moves the "written X frames" lower so that we don't trace

It's not compatible with any other element that use the non-striped
mode. In addition, in this mode, we require that every frame have the
same number of stripes or that the MARKER bit be present, which is
different from the other
formats too.

Use dedicated mutex/cond/flag for jobs being dispatched in the context thread.
The previous code was signalling the thread startup condition, which is wrong.
When WPEContextThread::dispatch() is invoked it means the thread has already
correctly been started up.

This has been a bad interpretation of the DRM docuemntation. The formats are
fixed regardless the CPU, but for some formats, they expressed in the opposite
order as GStreamer. Same change was done in waylandsink 2 years ago.
