Without these mappings, this controller "kinda" works out of the box:
- `SDL_GameControllerMapping()` works because it will notice "Xbox" in
the name and use the default XInput mappings
- `SDL_GameControllerMappingForGUID()` will not find any mapping
lsusb:
```
ID 2dc8:2000 8BitDo 8BitDo Pro 2 Wired Controller for Xbox
```
In Linux this controller is supported by two drivers:
- `xpad` (built-in to the kernel), exposes the controller name from the
USB descriptor and the GUID starts with 03 (0x03 = BUS_USB)
- `xone` (https://github.com/medusalix/xone), exposes a virtual
controller which is always named "Microsoft X-Box One pad" and the
GUID starts with 06 (0x06 = BUS_VIRTUAL)
This commit adds the 2 GUIDs from both drivers so mappings will always
be found and the real controller name will always be reported.
MessageBoxes attached to a window in macOS should use modal APIs and not
use a poll/sleep pattern on the main thread. Sleeping the main thread
makes the NSWindow message loop sluggish and interferes with external
applications that need to send messages to that window, such as
VoiceOver.
libdecor plugins can change the min/max window size values internally to enforce a minimum window size, and errors and crashes can result if the window size is below the internal limit.
On versions of libdecor >= 0.1.1, the minimum width and height can be queried and the minimum required window size will be enforced. The application requested window size is still respected, however, the actual window may be slightly larger than the drawable area to accommodate the required libdecor minimum size.
On version 0.1.0 of libdecor, which lacks the function to retrieve the minimum size, the internal limits are overridden before committing a frame, so that the internal limits always match the window size as a workaround, even if the window is technically smaller than the plugin would normally allow.

We are guaranteed that the lock will be held during shutdown, so if we are in InvokeRemoved(), it's because we're shutting down controllers and need to remove them from our internal list.

A previous cleanup commit inverted a statement that checked the return value of
a KMSDRM_CreateSurfaces call during KMSDRM_CreateWindow, which causes the video
backend to always fail despite success.
This commit restores the intended behavior.

The annotations have been added to SDL_mutex.h and have been made public so applications can enable this for their own code.
Clang assumes that locking and unlocking can't fail, but SDL has the concept of a NULL mutex, so the mutex functions have been changed not to report errors if a mutex hasn't been initialized. We do have mutexes that might be accessed when they are NULL, notably in the event system, so this is an important change.
This commit cleans up a bunch of rare race conditions in the joystick and game controller code so now everything should be completely protected by the joystick lock.
To test this, change the compiler to "clang -Wthread-safety -Werror=thread-safety -DSDL_THREAD_SAFETY_ANALYSIS"

It was previously thought that these function calls were unnecessary as the initial bug and reproduction case that necessitated their addition seemed to be fixed, but apparently there are still cases where this needs to be set explicitly. Set the xdg surface geometry at creation time and when the window size changes.
Partially reverts #6361. This is not needed in the libdecor path, as libdecor calls this for the content surface internally.
(cherry picked from commit 90a964f132c63b07cf85e5687041d214fdea60f6)
Num Lock and Caps Lock always need to be explicitly handled by the modifier handler function, or they won't be correctly set if active at application startup, or if the lock state is changed while the application lacks focus since a key press for these keys will never be received. In these cases, the internal SDL modifier state can end up the inverse of the actual modifier state.

I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base.
In general I let clang-format have it's way, and added markup to prevent formatting of code that would break or be completely unreadable if formatted.
The script I ran for the src directory is added as build-scripts/clang-format-src.sh

(cherry picked from commit 5750bcb174300011b91d1de20edb288fcca70f8c)
The new protocol adds support for more native communication of
fractional scaling.
Everything in the wayland backend already existed only our fractional
scale was calculated implicitly through a combination of output size
guesswork for fullscreen windows.
This new protocol makes that explicit, providing a more robust solution
and a solution for non-fullscreen surfaces. The fallback code is still
left in place for now whilst compositors gain support.

`argv[0]`/`getexexname()` are not always absolute paths by default and can be modified to anything the developer wants them to be.
Consider using `readSymLink("/proc/self/path/a.out")` instead and `getexecname()` as the fallback, since the symlink will always be the correct absolute path (unless /proc is ot mounted, but it is by default on Solaris and Illumos platforms).

This reverts commit 33a68f575f.
We don't want the G29 to show up as a gamepad, Steam will create a virtual Xbox controller for it, which breaks racing games.
When changing the window state from non-floating to floating (e.g. leaving fullscreen), libdecor can send bogus content sizes that are +/- the height of the window title bar and start 'walking' the window height in one direction or the other with every transition.
The floating window size is known, so use the cached value instead of the size reported by libdecor when restoring the floating state.
Some applications (and embarrassingly, testime is one of them) call
SDL_StartTextInput() or SDL_SetTextInputRect() every frame. On KDE/KWin
with fcitx5, this causes there to be several preedit events every frame
(particularly given some of the workarounds in Wayland_StartTextInput),
which slows testime down to an unusable crawl.
Instead, make SDL_StartTextInput() a no-op if text input is already
enabled, and cache the input rect, only changing it when the new rect is
actually different.
With these changes, we only get preedit events (and hence
SDL_TEXTEDITING events) when the preedit string actually changes. This
matches the behaviour under XWayland, and works very smoothly.
