Sam Lantinga 48e213b4cd Fixed SDL_ShouldQuit() returning false during status transitions 
We should wait for the state to stabilize before SDL_ShouldQuit() returns.

For example:
Thread A initializes and increments a use refcount
Thread B skips initializing and increments the use refcount
Thread B starts cleaning up and checks the use refcount
Thread A starts cleaning up, returns because SDL_ShouldQuit() returns false (not initialized), not touching the use refcount
Thread B returns because the use refcount isn't zero

Now we have the state where the refcount is greater than one and both thread A and B have attempted to cleanup.

With this change:
Thread A initializes and increments a use refcount
Thread B skips initializing and increments the use refcount
Thread B starts cleaning up and decrements and checks the use refcount
Thread A starts cleaning up, waits for thread B
Thread B returns because the use refcount isn't zero
Thread A continues and decrements and checks the use refcount, and finishes cleaning up because it has reached 0.

Simple DirectMedia Layer (SDL) Version 3.0

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. 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. If you are migrating to SDL 3.0 from SDL 2.0, the changes are extensively documented in README-migration.md.

Enjoy!
