aaee09d6ed Don't do NULL-checks before SDL_free() 
Replaces the pattern

  if (ptr) {
    SDL_free(ptr);
  }

with

  SDL_free(ptr);

8df057fafc iostream: Properly support the "x" mode for SDL_IOFromFile() 
The "x" mode for `fopen()` (open file only if it doesn't exist) used to
be a glibc-exclusive extension, but was later standardized in C11, and
is now also implemented as part of every other widely-used libc:

	* musl: https://git.musl-libc.org/cgit/musl/tree/src/stdio/__fmodeflags.c?id=0ccaf0572e9cccda2cced0f7ee659af4c1c6679a
	* Android Bionic / OpenBSD: 731631f300/libc/upstream-openbsd/lib/libc/stdio/flags.c (86)
	* Apple / FreeBSD: 63976b830a/stdio/FreeBSD/flags.c (L91-L92)

As a result, "x" has already been working on all our automatically
tested platforms that implement `SDL_IOFromFile()` via `fopen()`. So
all we'd be missing for proper support is a Windows implementation
using `CREATE_NEW`, and the documentation that this mode exists and is
intended to work.

9f9952d53a Fixed filesystem operations on iOS 
Full paths are used as-is, relative paths are prepended with a writable path, SDL_GetPrefPath("", ""), since the current directory isn't writable.

8d5b82be2e io: POSIX implementation tries to get status information on short reads/writes.

4d6e0e0087 io: read_fd should only report EOF on a zero-byte return value. 
POSIX says that's the EOF indicator, not a non-zero a short read.

b8197a2291 io: rework how we set SDL_IOStream status. 
This now relies on the implementation to set these flags on short reads/writes
instead of the higher level checking if SDL_SetError() was called.

Additionally (and crucially), this now sets ERROR or EOF on all short reads,
across all backends, not just when we get a zero-byte return value.

Fixes #13720.

07ef532681 hints: Renamed SDL_HINT_LOG_BACKENDS to SDL_DEBUG_LOGGING. 
This still logs backend choices, but we might use it for other things. For
example, what Android device is being used, or all the devices we enumerated,
etc.

Ideally this eventually logs all the stuff we often have to ask followup
questions about.
