This keeps the increment and decrement in the same compilation unit.

n_objectcore is incremented by ObjNew(), so HSH_Insert() should not
increase it again.

HSH_Insert() needs to take the same precautions as HSH_Unbusy() in
order to not race against e.g. the ban lurker. In order to do this, we
pass it the ban that the objcore should be associated with, and it
will take care of calling BAN_RefBan() correctly.

BAN_FindBan looks up a ban based on a ban timestamp and returns a
pointer to the ban. Returns NULL if no ban with that timestamp is
present.

BAN_RefBan takes an objcore and a ban. It grabs a reference to the ban
and associates the objcore with that ban.
