e7d6ddf593 Fix linking tiny overlay files (#755)
* Fix compatibility of rgblink -O and -t

The -t "tiny mode" option makes ROM0 cover 0x8000 bytes,
not 0x4000. The -O "overlay" option fills areas uncovered
by sections with data from an overlay file. These needed
to cooperate so that the calculated uncovered overlay size
does not exceed the actual size of the ROM.

Fixes #754

* Print link test names like asm tests do

* Make the three test.sh scripts more similar

748e7dd4c7 Fix calculation of 2**30
In exponent(), 'base *= base;' should not run
when base is 65536, since it overflows an int32_t.

This also optimizes exponent() based on
gcc and clang -O3 test cases in godbolt.org.

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.

Implement ** for integer exponents
** has higher precedence than -, like Python, so -3**4 == -(3**4) == 81

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

240fca0861 Fix Clang warning in linkdefs
This one's really stupid; printing an int with %hhu gives a warning
even though a regular unsigned char is promoted to an int before
printing anyway. Silence it so the build with Clang works.

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.

Fixes #307

RGBFIX can handle padding, so there's no reason why
we can't add an option to disable padding in rgblink.

d21015e34a Fix use of zero-allocated memory
It's possible that the unsigned integer may overflow to zero,
and then we might use zero-allocated memory.

This is incredibly unlikely, and I would even go so far as to say
that this is a false positive. Fix it anyway, to silence this warning:

src/link/patch.c:92:24: warning: Use of zero-allocated memory
        stack.buf[stack.size] = value;
        ~~~~~~~~~~~~~~~~~~~~~ ^

Deal with overflow, and check for zero to get rid of the warning.

Yet another case caught by scan-build:

                                ~~~~~~~~~^~~~~~~

Just copy over the code from the division case, with a few modifications.
