This changes the `SDL_EVENTS_DISABLED` path's return value from SDL_DISABLE
to SDL_IGNORE to match expectations, but doesn't actually change the ABI,
since these two symbols are both zero.

avoids -Wformat warnings from mingw toolchains -- e.g.:
src/test/SDL_test_harness.c:581:37: warning: unknown conversion type character 'l' in format [-Wformat=]

(psp-cmake defines `__PSP__` on the command line, but the compiler itself
only defines `__psp__` and some variations.
Fixes#9378.
(cherry picked from commit 0d8ce4a761)
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.

SDL_GetGamepadAxis() is a SDL3-specific name: SDL2 calls gamepads
"game controllers".

It would be easy to assume that all APIs that reference
SDL_JOYSTICK_AXIS_MAX work the same way, but they do not: triggers
generally use the full signed 16-bit range in the lower-level joystick
API, but are normalized to be non-negative by the higher-level gamepad
API.
We also never said explicitly which direction is positive here.
Experimentally, it's right (X), down (Y), and pressed (triggers).

The ARM926EJ-S Technical Reference Manual states:
> You can only access CP15 registers with MRC and MCR instructions in a
> privileged mode. CDP, LDC, STC, MCRR, and MRRC instructions, and unprivileged
> MRC or MCR instructions to CP15 cause the Undefined instruction exception to
> be taken.
Furthermore, `MCR p15, 0, <Rd>, c7, c10, 5` (later called Data Memory Barrier)
is not specified for the ARM926. Thus, SDL should not use these cache
instructions on ARMv5.

Added support for getting the real controller info, as well as the function SDL_GameControllerGetSteamHandle() to get the Steam Input API handle, from the virtual gamepads provided by Steam.
Also added an event SDL_CONTROLLERSTEAMHANDLEUPDATED which is triggered when a controller's API handle changes, e.g. the controllers were reassigned slots in the Steam UI.

- check libiconv with a linkage test with iconv.h included
- check libc iconv with a linkage test with iconv.h included
and LIBICONV_PLUG defined (in case libiconv header is in
include path)
- add new configuration option to prefer iconv from libiconv,
if available, over the libc version, defaults to disabled:
SDL_LIBICONV for cmake, --enable-libiconv for autotools.
- change FreeBSD specific LIBICONV_PLUG define in SDL_iconv.c
to configuration result.
This can be used to work around issues where the Apple GCController driver doesn't work for some controllers but there's no way to know which GCController maps to which IOKit device.
