nmlgc 70b4134af4 [Maintenance] [th04/th05] Assemble 16-bit .ASM files case-sensitively
Otherwise, TASM would simply convert all EXTRN declarations in those
files to uppercase. Then, the linker would expect them in uppercase,
forcing both the case-sensitive big 32-bit .ASM files *and* the entire
C land to declare them as uppercase as well.

For functions with __pascal convention which are always uppercased
anyway, this makes no difference. It does matter for regular __cdecl
variables, though, and the C declaration of [score_delta] in e6294c2
already showed that we'd then be forced to use macros if we wanted to
pretend that these names still had lowercase characters.

Doing this for every variable referenced in both C land and 16-bit ASM
land gets annoying quickly. So, no need to force this inconsistency if
we can get rid of it by slightly uglifying ASM land.

nmlgc 624b66f3ca [Maintenance] [th04/th05] Add a segment split before the title popup functions
A bit tricky with those ASM translation units near-calling functions in
the very first segment, and #pragma codeseg requiring an additional
group parameter to correctly calculate array offsets (including those
used for `switch` statements). But doable.

nmlgc d1f3dcd620 [Maintenance] Move all features exclusive to MAIN.EXE to a main/ subdirectory
Adding op/, main/, and end/ directories does nicely cover a great
majority of the "not really further classifiable slices" implied in
d56bd45.

nmlgc b37611b1be [Maintenance] Add an underscore to the player_pos variable
No need to declare them as `pascal` on the C side only because I messed
up when naming them first.

nmlgc a533b5d3ea [Reverse-engineering] [th04/th05] Player sprite area invalidation
And once again, the TH05 version is un-decompilable. :/ It was pretty
close this time, though, as the entire block between PUSH DI and POP DI
kind of resembles a separate inlined function, in accordance with Turbo
C++'s  automatic backup of the DI register, as researched in 7f971a0.

Except that it contains a loop, and Turbo C++ refuses to inline any
function with `do`, `while`, `for`, or `goto`. If it didn't, it would
have totally worked.

Also, yes, C++ class methods are treated identically in this regard.

Oh well. Shot type control functions next, finally!
