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/`.)

Much more than usual, now that we've got a snappy build system! This
commit covers
• All .PI functions across all games
• TH02's High Score entry functions
• TH03's shots_update() and shots_render()
• All functions declared in `th04/op/op.hpp`
• TH04/TH05's bb_txt_put_8_raw(), bullet_template_clip(),
player_pos_update_and_clamp(), score_update_and_render(), and
slowdown_frame_delay()
• TH05's reimu_stars_update_and_render(), score_delta_commit(),
stage2_invalidate(), stage2_update(), and space_window_set()

If the macro itself is local to a function, these can work in certain
scenarios, but never for global ones.

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

This gets rid of a couple of per-entity sprite bitplane types, makes
sprite declarations easier to read by putting width and height next to
each other… and points out a number of array dimension mistakes -.-
Even in places where we can't use it.

Might look uglier, but has the advantage of not generating an empty
segment with the default name… *and* the default padding, which will
really come in handy with the following breakthrough.
