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.

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:
src/link/patch.c:188:21: warning: Division by zero
value = popRPN() % value;
~~~~~~~~~^~~~~~~
Just copy over the code from the division case, with a few modifications.

This was made separate with the intention of supporting multiple versions,
but after some discussion this was decided against, so better improve
readability instead.
"fixed" and "aligned" location checking advanced the target location to places
regardless of the associated free space, potentially breaking the assumption
that the location was always further in memory than the free space's base.
Rather than adding more code to try keeping that assumption true, harden
`isLocationSuitable` and handle that case as well.
`char` has implementation-defined signedness, and if it's chosen to be unsigned,
then -1 gets converted to 255, which is then promoted back to `int` as... 255,
always failing the loop condition in src/link/main.c:118
`int8_t` has the correct signedness, but considering `musl_getopt_long_only`
returns `int`, better use that so as not to lose any bits
