[Maintenance] Prefer the -zC and -zP options over `#pragma codeseg` Might look uglier, but has the advantage of not generating an empty segment with the default name… and the default padding, which will really come in handy with the following breakthrough.

[Maintenance] Copy <dos.h>'s 16-bit x86 Real Mode declarations to a new file DOS is not the same thing as the underlying CPU, after all. A separate file not only indicates to future port authors which parts of the code are x86-specific, but it also speeds up build times… … in theory, because removing 677 lines from 49 files each doesn't seem to speed up the build as much as I had hoped? But apparently my whole system mysteriously got faster in the meantime, and I was getting 22-23 seconds for the entire repo even before this commit. Good enough.
