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.

We either need to explicitly test using the sRGB colorspace or update the tests for HDR10 color conversion. We'll just disable them for now, as these formats aren't commonly used in games.

The function calls strcmp internally without checking for a null string parameter, and calling strcmp with a null parameter is undefined behavior.

- Move legacy name choice to a separate function, so we can `return` a
string in one line instead of assign a variable and `break` for each item.
- Have the case statement cover SDL_NUM_SYSTEM_CURSORS, and not `default`, so
compiler will (maybe) warn us if an enum value is added but not included here.
- Only choose a legacy name if necessary.

These previously mapped SIZEALL to "move", but "move" is not guaranteed
to be a four-pointed arrow: according to the CSS spec, it's actually
intended to be a drag-and-drop cursor, analogous to "alias" and "copy".
Map it to "all-scroll" instead, as in Wayland: while this is *also* not
semantically guaranteed to be a four-pointed arrow, it is at least
*suggested* to make it a four-pointed arrow.

SDL3's Wayland code already uses the CSS names exclusively with no
fallback, but since SDL2 has historically used the older names, keeping
them as a fallback makes sense if the CSS names don't work out.

The "left_ptr" name is an X11 thing, and there's no guarantee that
Wayland cursor themes contain it. In particular, GNOME's Adwaita theme
as of version 46.beta only contains the CSS/freedesktop names.
To test, either move one of the known cursors out of the way, or edit
the switch statement above to use a wrong name for one of them.

(cherry picked from commit e2535ba547)
Apparently this is necessary on the latest Gnome to get properly themed
cursors, vs ancient X11 standard cursors, as Gnome has dropped the old
theme names that XCreateFontCursor eventually expected to find.
Fixes#8939.

mingw-w64 has added this from Proton (which added this from SDL), so we need to re-define it as a local symbol to avoid conflicting with mingw-w64 headers.

Add missing guards around use of physicalInputProfile.

Add __unsafe_unretained to ObjC types in struct so the compiler doesn't
complain about that not being allowed with ARC.

These originally checked for expected ± EPSILON as logged, but since
commit 880c6939 they check for expected ± max_err, where max_err may
need to be greater than EPSILON for very large expected results like
the ones in exp_regularCases().
Also, EPSILON is so small that the default precision of the %f format
(6 decimal places) would never actually have shown its effect, so log
it in scientific notation instead.

While looking at the other tests in this file, I noticed that instead
of checking for a result in the range of expected ± FLT_EPSILON as I
would have expected, these tests would accept any result strictly less
than expected + FLT_EPSILON, for example a wrong result that is very
large and negative. This is presumably not what was intended, so add
the SDL_fabs() that I assume was meant to be here.

In the Steam Runtime 1 'scout' environment, when compiling for i386
