nmlgc efff8d61bb [Maintenance] Change line endings in old C/C++ files to LF
Yup, even a DOS compiler from 1994 considered CRLF line endings as
stupid.

nmlgc e1d5bdafed [Maintenance] master.hpp: Type-safe hmem_allocbyte() and hmem_free() wrappers
Sure, we can't use them everywhere, but it's really nice to get rid of
that casting madness – and any explicit references to x86 memory
segmentation – wherever we can.

nmlgc bda7b16758 [Maintenance] Move the polar coordinate conversion functions to their own file
math/vector.hpp needs zero dependencies, this needs master.hpp.

nmlgc d25daf7075 [Maintenance] Move the number of VRAM planes to pc98.h
Allowing us to consistently mirror the declaration in pc98.inc
without adding a planar.inc file. 😛 And points us to two more
dots8_t* arrays that should have used the Planar<> template.

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 604b2c83ac [Maintenance] Avoid MK_FP() where possible
It's not necessary for assigning `__seg` pointers to `far` ones, which
might even remove the <dos.h> dependency in some translation units.

nmlgc 21d82fab04 [Maintenance] Declare the input bitflags in a consistent way
Turns out the inlining behavior of `const` variables at global scope
that we've been relying on lately is actually exclusive to C++ mode…
once again!

nmlgc 0bfff60a0a [Maintenance] Define `bool` as unsigned
Wait, we can just do that, and nothing breaks?! All this time, we
could have avoided the `unsigned char` workaround???

nmlgc 8266bbd83e [Maintenance] Start a C++ master.lib header file
The regular master.h is big, uncomfortable in C++ mode, and bloated
with all those portability `#define`s that effectively only cover a
small portion of the PC-98-specific code anyway. So, let's gradually
transition to a new smaller header that is more integrated into the
ReC98 codebase, by simply no longer #including `master.h` in new code.

Which also explains its weird place in the root directory. Even though
`libs/master.lib/` contains plenty of game-specific modifications, it
didn't feel right to have anything in this directory refer to types
from `pc98.h`.

nmlgc 164591f9fe [Maintenance] Consistently express angle literals in signed hex format
Originally just a workaround to remove angles from the PI counter, but
having the sign indicate the Y direction also makes them a lot nicer to
read in C land.

nmlgc fe4c92a066 [Maintenance] [th01] Add separate functions for polar coordinate calculation
I'm still impressed that something like this perfectly inlines in every
place that uses this functionality so far. Maybe something about each
parameter only being used once inside the single expression of the
function?

nmlgc ba29539fc7 [Maintenance] Declare a distinct type for VRAM offsets
… and this one, while I'm at it. I've been using pretty much every
possible type for VRAM offset variables, depending on my mood that day,
since signedness apparently never matters for those.
Except that it does. And so, just like with most of our high-level
types, we also have to account for ZUN's little signedness
inconsistencies here. Oh well, at least it's now only one of two types,
and there's no need to choose between `int` or `unsigned int` or
`short` or `unsigned short` or `int16_t` or `uint16_t` or `size_t` or…

nmlgc 368f151759 [Maintenance] Declare distinct types for screen, VRAM, and TRAM coordinates
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.

nmlgc bd1c2ee7de [Maintenance] #define the number of dots in a byte
One fewer magic number. And one more deliberate dependency on a
PC-98-specific hardware constant, to further drive home just how
unportable these games are, even once decompilation will be complete.

nmlgc a75e0f8f53 [Maintenance] Compile all VRAM-accessing translation units as C++
Leading to slight complications in TH02's Music Room and shot type
selection menus. Thought about leaving those in C for a while, but I
still think it's worth it for the consistency we get with the VRAM
offset functions. Also, we'll have similar code for the main menus of
later games, and I'll surely won't be using C++ when starting out with
these.
