nmlgc f99d7a571c [Maintenance] Remove all dependencies on Borland C++ run-time source headers
And with all possible .COM executables decompiled, this set of changes
reaches an acceptable scope, allowing us to *finally*…

nmlgc 6363a37d7a [Maintenance] Move TH02's sound functions to a separate header
Oh hey, guarding declarations with complicated types via #ifdef limits
the header files we additionally have to #include!

nmlgc 9cb6cc527a [Decompilation] Finally declare <stdint.h> types
*Finally*. We already used `(unsigned) int` in quite a few places where
we actually want a 16-bit value, which was bound to annoy future port
developers.

nmlgc db4de240e9 [Decompilation] Prepare the C side for the shot type control functions
That should make this convoluted copypasta a bit easier to read. And
sure, I could have done something about the loop as well, but
SHOT_FUNC_INIT already hides enough control flow behind a macro…

nmlgc c5f53d9cf1 [Maintenance] Rename snd_kaja_func() to snd_kaja_interrupt()
Oh, right, these functions can have parameters. So, let's turn snd_kaja_func()
into a macro that combines the function number and the parameter into the AX
value for the driver.

nmlgc de491f225d [Maintenance] Move the sound driver function slices from hardware/ to snd/
And renaming them all to the short filenames they will be decompiled to for
consistency. These functions aren't really immediately hardware-related, as
we've established earlier in the decompilation.

nmlgc 92979e8f31 [C decompilation] [th02] Code segment #2 of all three executables
Only one code segment left in both OP and FUUIN! its-happening.gif

Yeah, that commit is way larger than I'm comfortable with, but none of these
functions is particularly large or difficult to decompile (with the exception
of graph_putsa_fx(), which I actually did weeks ago), and OP and MAIN have
their own unique functions in between the shared ones, so…

nmlgc f3b8ae2851 [C decompilation] [th02/op] Second set of sound driver calls
So yeah, after ignoring this issue for a week, we indeed have no choice but to
decompile these functions into this horrible mess of C and inline assembly.
And you know what? Since the compiled result still matches with ZUN's binary,
it's entirely possible that this *was* the original format this code was
written in! Seriously, how intoxicated do you have to be to write (or rather,
slur) code like this?

Keeping these functions entirely in assembly would have surely been better.
However, it would have made linking practically impossible, especially for the
later games which still need them in the current assembly slice format.
