- 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.
This reverts commit b9ab326982.
@rainerdeyke pointed out:
"This commit is incorrect. Flipping both horizontally and vertically is not equivalent to flipping diagonally."
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 SDL_RenderFlip is an enum, SDL_FLIP_HORIZONTAL and SDL_FLIP_VERTICAL can not be OR'ed to get the "SDL_FLIP_DIAGONAL".
Render code is actually able to perform these 3 kind of "flipping" so I just added a new enum called SDL_FLIP_DIAGONAL with the OR'ed value (3) so it can be used.
