Add the xdg-foreign-unstable-v2 protocol and use it to create export handles for toplevel windows, which will be used when an external component, such as the file chooser portal, requires it.
- SDL_RWops is now an opaque struct.
- SDL_AllocRW is gone. If an app is creating a custom RWops, they pass the
function pointers to SDL_CreateRW(), which are stored internally.
- SDL_RWclose is gone, there is only SDL_DestroyRW(), which calls the
implementation's `->close` method before freeing other things.
- There is only one path to create and use RWops now, so we don't have to
worry about whether `->close` will call SDL_DestroyRW, or if this will
risk any Properties not being released, etc.
- SDL_RWFrom* still works as expected, for getting a RWops without having
to supply your own implementation. Objects from these functions are also
destroyed with SDL_DestroyRW.
- Lots of other cleanup and SDL3ization of the library code.
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.

Use memfd_create() to allocate the temporary SHM backing file in memory, and set the size with posix_fallocate(), which will return an error on insufficient space vs ftruncate(), which will silently succeed and allow a SIGBUS error to occur if the unbacked memory is accessed.
Additionally, make the legacy path more robust by unlinking the temp file, so it won't persist after close, and unmapping the shared memory buffer.
This broke support for the Hori Fighting Stick EX2, which gets a good mapping if the automatic mapping is allowed to create one.
If the original controller needs a mapping, it should be added with a crc, since that VID/PID combination is used by several HORI controllers.
While the focus change happens, Windows appears to reset the cursor clip rectangle, and then restore it if the application that has focus has the clip rectangle set.
This fixes resetting the clip rectangle while changing focus between windows in the same application, e.g. the Source 2 editor.
This adds HIDAPI support for DualShock 3 controllers on Windows, addressing the current absence of this feature in SDL. To utilize this functionality, the official Sony driver 'sixaxis.sys' must be installed. HID offers several advantages over DirectInput, including rumble support and the ability to control the LED lights that display the controller number.
On Android, HIDAPI prompts for permissions and acquires exclusive access to the device, and on Apple mobile platforms it doesn't do anything except for handling Bluetooth Steam Controllers.

Previously there were two different paths for renderer creation, and the HDR metadata initialization was missing when creating a software renderer for a surface. Now all the cases are handled in a single path, so regardless of whether you create a software renderer by name, a software renderer for a surface, or fall back to a software renderer, you'll get the correct initialization in all cases.

Since commit 0dfdf1f3 "Fixed crash if joystick functions are passed a
NULL joystick", we've already done this check by the time we get to
this point.

Separately checking the state of a file before operating on it may allow
an attacker to modify the file between the two operations. (CWE-367)
Fix by using fstat() instead of stat().
Found in the wild from minidump reports. Unclear displaydata is null, but according
to the API it is possible for this call to return null so it seems like a valid check.
When the titlebar drage region is clicked two actions are triggered:
* The WM transfers focus to the application
* The application starts a drag operation because the drag region was clicked
When the drag operation starts before input has been transferred to the application the
window manager gets in a bad state where mouse clicks don't work and the system isn't
actually dragging.
In this CL we delay drag operations until after the application has acquired active focus.
This fixes the problems outlined above.
