This is a release candidate for 2.30.0

Thanks for all the feedback! This update fixes WASAPI audio issues, improves Android audio latency, fixes Android audio device hotplugging, fixes a crash when accidentally opening a directory as a file, improves the timing of SDL_WaitEventTimeout() on Windows, and adds the SDL_LOGGING environment variable.

In addition to lots of bug fixes, here are the major changes in this release: General:

• Added support for 2 bits-per-pixel indexed surface formats
• Added the function SDL_GameControllerGetSteamHandle() to get the Steam API handle for a controller, if available
• Added the event SDL_CONTROLLERSTEAMHANDLEUPDATED which is sent when the Steam API handle for a controller changes. This could also change the name, VID, and PID of the controller.
• Added the environment variable SDL_LOGGING to control default log output

macOS:

• Added the hint SDL_HINT_JOYSTICK_IOKIT to control whether the IOKit controller driver should be used
• Added the hint SDL_HINT_JOYSTICK_MFI to control whether the GCController controller driver should be used
• Added the hint SDL_HINT_RENDER_METAL_PREFER_LOW_POWER_DEVICE to choose whether high or low power GPU should be used for rendering, in the case where there are multiple GPUs available

Xbox:

• Added the function SDL_GDKGetDefaultUser()
