80218fa109 Fix array overflow on invalid macro arg evaluation
`macro_GetArg` had not been changed after the previous commit; however,
the old code relied on the `macroArgs->args` array being at least
`MAXMACROARGS` entries large (which was the case until the last commit).
The boundary against which it checked would have better been written as
`sizeof(macroArgs->args)/sizeof(macroArgs->args[0])`, I guess, but what's
done is done.

5c24de3dc4 Use inttypes for stdint types
This should help make RGBDS portable to systems with 16-bit integers,
like DOS.

For kicks, use the macros for 16-bit and 8-bit integers.

Fix other miscellaneous things, like #include ordering and other
printf-format related things.

Reduce repitition in math.c while I'm there.

b299f6fb3b Fix uninitialized memory use with -MT and -MQ
This didn't break unless the first uninitialized byte was non-zero,
which happened to be the case on someone's Windows machine.

Would it be worth it setting up Valgrind in CI?

5863cd10b8 Fix possible null pointer dereference
It's possible that if the FILE passed to yy_create_buffer is at the
end-of file, there may be a null pointer dereference.

This should hopefully fix that.

Found with clang-tools' scan-build:

src/asm/lexer.c:281:25: warning: Array access (via field 'pBuffer')
 results in a null pointer dereference
        pBuffer->pBuffer[size] = 0;
                 ~~~~~~~       ^
1 warning generated.

RGBLINK is capable of handling it now.
Though it'd be ideal for RGBASM to directly catch it.

db1eb8fbcb Revert "Prevent RGBASM from outputting corrupted files"
This reverts commit 06fe27c516.

According to Microsoft's documentation
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/tmpfile?view=vs-2019
`tmpfile` attempts to create the temporary file at the **root** folder
This seems to assume that the user has admin rights; might be a compat
thing, idk, but it breaks on people's computers.
(CI didn't catch it, annoyingly.)

Reverting to make RGBASM usable on most Windows computers.
(Sanely-configured ones, at least.)
Another solution to #446 needs to be figured out, yay...

cb52ae0f26 Implement unionized sections in RGBASM
This touched a lot more code than initially expected, for two reasons.

First, this broke a big RGBASM assumption: that sections are always being
written to at their end. This plus other problems required touching
basically the entirety of `section.c`.

Second, I tried different solutions to solve the above problem, and along
the way I cleaned up many things around. (I believe that keeping this to
"cleanup" commits yields subpar results, and since it's boring they get
postponed anyways.)

RGBLINK support still needs to be added, but this will come next.
