wasapi: Deal with HDMI or DisplayPort-based audio devices. 
They can vanish for UP TO EIGHT SECONDS...!

This is for devices that connect to HDMI/DisplayPort/etc, where it
presumably has to wait for a display to get up and running before it
can play audio through it, so one can see the audio device fail when
changing display modes, or the system returning from sleep. Since this
can be triggered by a game changing video resolutions at startup (either
before or after opening the audio device!), it's important to deal with.

In normal conditions, it shouldn't take this long to open or recover an
audio device, but this is better than unexpectedly losing the device
in this situation.

Fixes #7044.
Fixes #5571.

Simple DirectMedia Layer (SDL) Version 2.0

https://www.libsdl.org/

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award winning catalog and many Humble Bundle games.

More extensive documentation is available in the docs directory, starting with README.md

Enjoy!
