Remove long_u: hashtab: Refactor other types.

Current type of some other parameters/variables can be improved:
- hashtab_T         : ht_error : int  -> bool.
- hash_clear_all()  : off      : int  -> unsigned int.
- hash_clear_all()  : todo     : long -> size_t.
- hash_may_resize() : todo     : int  -> size_t.
