Now multiple XInput controllers map correctly to device indexes instead of grabbing
the first available userid, and are completely separated out from DirectInput.
Also, the hardcoded limitation on number of DirectInput devices is gone. I don't
expect there to really ever be more than eight joysticks plugged into a machine, but
it was a leftover limitation for a static array we didn't actually use anymore.
Fixes Bugzilla #1984. (etc?)
- detect that you tried to open a gamecontroller in xinput mode and failed, then re-get the mapping for the dinput variant you did open (and most likely now just fail the open)
CR: SamL
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.
