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.

By now, it has become clear that this the norm rather than the
exception among these units. Thankfully!

The later games need this constant for their buffers as well, and it's
not just needed for loading sound files. Might be overkill to force all
of `master.hpp` to be #included in some additional places, but the
alternative would have been to move it to a `fn_len.hpp` file.
Ultimately, this constant *is* related to master.lib.

The single underscore version is actually slightly more supported among
the compilers I've seen so far. Also added the exact list now.

Last one! Done with the SHARED segment for the forseeable future! 🎉
Sure, not the best C++ code either, but still by far the sanest
implementation of this function in any of the 4 games.
