nmlgc f5da2a50a5 [Maintenance] [th02/th04/th05] Stage tiles: Move metrics to a separate header
The vertical shmup counterpart to 841d8be. Cleans up the subsystem
hierarchy by ensuring that at least all tile /formats/ code does not
depend on /main/ code.

nmlgc 0ffa756cae [Contributing] Decide on `seg` and `off` for x86-segment-related identifiers
I could have equally argued the opposite way, and in favor of `sgm` and
`ofs`, but I've also been using `seg` and `off` more prevalently
throughout the years.

nmlgc f635948480 [Naming] .MPN: Rename mptn_* to mpn_*
We've been using the three-letter extension names for everything else
that isn't .DAT, so it's more consistent to do the same for .MPN,
however particularly nice and readable its FOURCC may be. 8.3 filenames
also really appreciate that they'll have to accommodate one fewer
letter.

segmentation – wherever we can.

Segment alignment forces us to do all of those at once… but now, we've

MAINE.EXE, but also decompiled all instances of DEFCONV functions!

nmlgc 1244bd74e7 [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.

nmlgc 0d66e748d1 [Maintenance] Replace wrong `cPtrSize` usage with the ARG directive
Turns out that ARG RETURNS is only really necessary in DEFCONV
functions, which are explicitly declared to use either the C or PASCAL
calling convention. In functions without such a declaration, ARG by
itself works just fine, and won't emit any instructions on its own.
The parameter lists for PASCAL functions still have to be reversed in
that case, though… oh well, let's just comment these cases to hopefully
reduce the confusion.

nmlgc 1c5ed4b06e [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.

nmlgc f6757fe76a [Maintenance] Fix DEFCONV declarations, and remove them where possible
Wow, this is the first time we're about to call any of these from C
land in ≥TH03? Found no built-in way to just uppercase an identifier
in TASM, so apparently we have to spell out the names in both lower-
and uppercase.
So, let's go back to regular, non-macro PUBLIC / PROC / ENDP code
wherever we can – for all functions introduced in ≥TH03, and for
everything that takes no parameters. It's simply not worth the
trouble.

Whew, time to look at every `int` variable we ever declared! The best
moment to do this would have been a year ago, but well, better late
than never. No need to communicate that in comments anymore.

These shouldn't be used for widths, heights, or sprite-space
coordinates. Maybe we'll cover that another time, this commit is
already large enough.

because all the RES_*.COM binaries still had some different instruction
