Since a few annoying alignment bytes suggested more translation units
than previously expected, using many small headers has proved to be
better than one big shared TH04/TH05 header file. Or should we *really*
pepper the code with lots of `#pragma codestring`? 😛
And in case we have multiple translation units which all #include the
same set of headers, we'll just go with situational shared headers,
using a common prefix.

*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.
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…
