The audio_enumerateAndNameAudioDevicesNegativeTests test in testautomation_audio.c reports a failure for SDL_GetAudioDeviceName when called on a driver that has only the default device. SDL_GetNumAudioDevices reports 1, but SDL_GetAudioDeviceName does not check if the index passed by the caller is in that range in this case. For positive numbers anyway.
This can be reproduced with the dummy driver on Windows and Linux.

The problem in question is caused by changeset 7771 (http://hg.libsdl.org/SDL/rev/5486e579872e / https://bugzilla.libsdl.org/show_bug.cgi?id=2121)
The redefinition of __inline__ (introduced by the addition of begin_code.h:128's "|| __STRICT_ANSI__") results in mingw's gcc throwing multiple
warning: always_inline function might not be inlinable [-Wattributes]
as well as a whole bunch of redefinitions of mingw internals which break linking of projects including the SDL2 headers.
If the app is in landscape mode and the user presses the power button, a pause
is followed immediately by a surfaceChanged event because the lock screen
is shown in portrait mode. This triggers a "false" resume.
So, we just pause and resume following the onWindowFocusChanged events.
Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before
blocking the event pump.
