With the upcoming `#include` cleanup, it finally makes sense to split
off all graphics-related code into its own header. In turn, it makes
more sense to store all of these future master.lib headers in, well,
the master.lib directory, which provides a new 8 characters for their
file names. Turns out that the rationale I gave for the root directory
placement in 8266bbd didn't hold up 3½ years later…
(Also, the `pc98.h` declarations will eventually be split into
`game/coords.hpp` and something in `platform/x86real/pc98/`.)

The translation units were probably a better place back when most of
the codebase was still compiled in C mode, we only had a few C++ TUs,
almost everything needed to be declared as `extern "C"`, and moving
these declarations into the headers would have been really noisy with
all the `#ifdef __cplusplus` / `#endif` required. Nowadays though,
we've greatly reduced that surface area. And given that headers will
include even more headers as part of the upcoming `#include` cleanup,
it makes sense to make the jump now.

These functions are placed rather far away from other stage-related
code, which suggests a distinct translation unit.

Biggest decompilation breakthrough of the year already? Completely
removes the need for the "set near pointer to far function" hack, and
solves quite a few upcoming issues.
The TASM manuals did have a few pages on the topic of segments and
groups, but there's absolutely nothing about it in the TCC ones beyond
the three-sentence description of `#pragma codeseg` and that completely
unhelpful "🤷" of an explanation for the `Fixup overflow` error…

There's the meaning I was looking for in 6ff427a! Far from everything
that's done with this "mode change" variable though – and as we've seen
in 426a531, it's mostly a waste of time to immediately RE all meanings
of this variable across all bosses. So, let's keep using the raw
"phase_state" variable in ASM land.

Way easier to read compared to the mental gymnastics of the original
"offset + range" form, especially since we can also abstract away
subpixels with another layer of wrapper functions. Also brings a bunch
of new speed/angle symmetries to light.

The fanciness of expressing these as signed constants probably hurted
the understandability of the code more than it helped.

Awesome! The last of the shared TH04/TH05 boss functions, completed
just as the money for that sort of thing ran out. Time to decompile
some actual bosses!

With TH04's version hardcoding not only Gengetsu's dialog and
initialization, but also the Bad Ending after having clearing Stage 5
with continues or on Easy difficulty.
