b3c0db218d Remove "EOF-newline" lexer hack
In preparation for an upcoming change
Makes for nicer error messages, complaining about EOF instead of newlines
The hack had to be kept for the lexer raw mode to avoid a bug;
see the relevant code comment for more info.

4f842a1248 Create specialized symbol finder functions
The old "find symbol with auto scope" function is now three:
- One finds the exact name passed to it, skipping any checks
  This is useful e.g. if such checks were already performed.
- One checks that the name is not scoped, and calls the first.
  This is useful for names that cannot be scoped, such as checking for EQUS.
  Doing this instead of the third should improve performance somehwat, since
  this specific case is hit by the lexer each time an identifier is read.
- The last one checks if the name should be expanded (`.loc` → `Glob.loc`),
  and that the local part is not scoped. This is essentially the old function.

b1adbcc77c Output a non-empty RPN buffer from known expressions
The code expected to never get "known" expressions passed in, as RGBASM
otherwise patches the bytes in by itself; however, JR cannot be patched in
by RGBASM unless the section's base address is known as well!

e51701acaa Add platform-specific fixes file
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

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.

I am not sure this is the best (in cases where the target directory
is not writable but the target file is), but maybe this can be
toggled via a flag, for example.

12f2f654dd Add -MG
This option allows for automatic dependency detection and generation:
as soon as a missing file is found, it is output to the dep file, and
assembly immediately aborts. (No .o file is produced, even if `-o` was
speicified.) This doesn't cause an error, either; the point is that once
the file is added to the dep file, the Makefile is re-parsed, and this
time the file will be generated, so the dep list builds up automatically.
This mimicks GCC's option and behavior.

e3ef194b4f Remove local label error checking
This is actually not necessary, because RGBLINK would warn about missing labels.
Besides, through semi-esoteric ways, it is possible to define more labels in this scope,
and there's no reason to prevent that.
