Split hunt and huntd's includes, instead of incestuously sharing a pile

of external data and function declarations between the two programs.

Common constants and defines now go in hunt_common.h. Stuff that belongs
only to hunt is in hunt/hunt_private.h. Stuff that belongs only to huntd
is in huntd/hunt.h.

Copy some declarations that are used in both programs under the same
names (but are not actually the same objects) from huntd/hunt.h to
hunt/hunt_private.h. Move others that are only used in hunt. Remove
some entirely unused material, and tidy up standard includes.
