This declares that any `const char *` returned from SDL is owned by SDL, and
promises to be valid _at least_ until the next time the event queue runs, or
SDL_Quit() is called, even if the thing that owns the string gets destroyed
or changed before then.
This is noted in the headers as "the SDL_GetStringRule", so this will both be
greppable to find a detailed explaination in docs/README-strings.md and
wikiheaders will automatically turn it into a link we can point at the
appropriate documentation.
Fixes#9902.
(and several FIXMEs, both known and yet-undocumented.)
The CRC is used to distinguish between different controllers that have the same VID/PID, so if the CRC doesn't match, it's probably a different controller that we don't know about.

We were accidentally skipping all of the mappings that used the SDL_GAMECONTROLLER_USE_BUTTON_LABELS hint, because they used the '!' negate operator with a default hint value of 1. Instead we just want to use that hint to determine whether the mapping has positional buttons or not, and swap the buttons as needed.

This makes it easier for games that don't use the gamepad API to handle D-Pad navigation, and is consistent with many other non-HIDAPI mappings.
Fixes https://github.com/libsdl-org/SDL/issues/8754
Added support for getting the real controller info, as well as the function SDL_GetGamepadSteamHandle() to get the Steam Input API handle, from the virtual gamepads provided by Steam.
Also added an event SDL_EVENT_GAMEPAD_STEAM_HANDLE_UPDATED which is triggered when a controller's API handle changes, e.g. the controllers were reassigned slots in the Steam UI.
This means the allocator's caller doesn't need to use SDL_OutOfMemory directly
if the allocation fails.
This applies to the usual allocators: SDL_malloc, SDL_calloc, SDL_realloc
(all of these regardless of if the app supplied a custom allocator or we're
using system malloc() or an internal copy of dlmalloc under the hood),
SDL_aligned_alloc, SDL_small_alloc, SDL_strdup, SDL_asprintf, SDL_wcsdup...
probably others. If it returns something you can pass to SDL_free, it should
work.
The caller might still need to use SDL_OutOfMemory if something that wasn't
SDL allocated the memory: operator new in C++ code, Objective-C's alloc
message, win32 GlobalAlloc, etc.
Fixes#8642.
Automatically map controllers as gamepads when using the GCController framework and prefer the physicalInputProfile when possible.
Testing with macOS 13.4.1, macOS 14.1.1, iOS 15.7.4, tvOS 17.1:
* iBuffalo Classic USB Gamepad (macOS only)
* Logitech F310 (macOS only)
* Apple TV remote (tvOS only)
* Nimbus MFi controller
* PS4 DualShock controller
* PS5 DualSense controller
* Xbox Series X controller
* Xbox Elite Series 2 controller
* Nintendo Switch Pro controller
* Nintendo Switch Joy-Con controllers
This gives applications and binding systems a clearer view of what the hardware is so they can make intelligent decisions about how to present things to the user.
Gamepad mappings continue to use abxy for the face buttons for simplicity and compatibility with earlier versions of SDL, however the "SDL_GAMECONTROLLER_USE_BUTTON_LABELS" hint no longer has any effect.
Fixes https://github.com/libsdl-org/SDL/issues/6117
The following objects now have properties that can be user modified:
* SDL_AudioStream
* SDL_Gamepad
* SDL_Joystick
* SDL_RWops
* SDL_Renderer
* SDL_Sensor
* SDL_Surface
* SDL_Texture
* SDL_Window
