Use C11 standard _Noreturn instead of attributes (except, of course, MSVC)
Remove unused helpers
Avoid trapping in release builds, in favor of just unreachability
Improve shim when __builtin_* are not available
Create a new file, platform.h, for platform-specific hacks
for MSVC, this includes defining strncasecmp to _stricmp and
strdup to _strdup, among other things like defining missing
stat macros
Change some things not supported in MSVC, like _Static_assert,
to their counterparts (in this case, static_assert)
Replace usage of VLAs with malloc and free
Update getopt_long and use the getopt implementation from musl
on Windows.
Use comments to show which functions from platform.h are being used
While compiling for empscripten there is a duplicate symbol conflict with these two variables. And as they are only used locally, and do not need a symbol exported they can just be static.
The error was due to casting `const` away for permuting argv
elements, which is necessary for a libc for compatibility with older
systems, but not for us.
Checkpatch will complain about the style not being followed, but this is not
our code, so it can be ignored.
Both `getopt_long` and `getopt_long_only` are GNU-specific, so we'll be
copying musl's implementation for portability.
This was retrieved as of commit 90251cf73dfdd44e7a3f085d236e89a7dff1b00b.
musl is licensed as MIT, which is compatible (being identical...) to RGBDS'.
The file is being copied as-is, without a copyright notice or attribution,
but this is only to have a verbatim copy in the history. Those will be added
in the next commit.
The stdlib functions specify the difference between `err` and `errx`
is that the former prints a message obtained with `strerror`.
However, RGBDS' implementation breaks that contract, and `warn`'s puts the
added semicolon in the wrong place.
Added define 'unused_' for '__attribute__((unused))'. The oldest version
of GCC with online docs (GCC 2.95.3, released in March 16, 2001 [1])
already has support for this attribute, so it doesn't make sense to
check the version.
Renamed 'noreturn' to 'noreturn_' for consistency.

There was only one place where `strlcat` was used, and `snprintf`
actually does a better job at what the code was trying to achieve.

If the folder where the code is compiled is a valid git repository, the
version string is generated with `git describe`. If it isn't a valid
repository, a string included in the source code is used instead. This
one must be updated regularly as the toolchain is developed.

The error message shouldn't specify the name of the binary, that's
supposed to be known by the caller.
Update test reference outputs.

Improve error messages generated by `errx()`, `warnx()` and similar.
Set `progname` to a static string with the name of the program so that
the path of the binary isn't included in error messages.
