This includes not checking the result of malloc and
using the wrong type in sizeof. Only the latter was
caught by scan-build.
Also use more idiomatic sizeof().

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.

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.

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...
See individual comments within `rgbds.css` for more info
Not too fond of having to modify `mandoc.css`, but I did my best to
modify as little as possible
Adds links to argument descriptions in synopsis
Adds links to man pages in the set (not to external ones)
Removes artifact from the way long opts are encoded
Makes description blurb inline, consistently with terminal output
