Remove long_u: hashtab: Refactor long_u type.

hashtab.h:
- hash_T: long_u -> size_t.

  In principle, a hash value could thought of as just an unsigned number
  without size semantics (uint32_t or uint64_t).  But it is used as
  index at some places, and so, size_t is also eligible. Therea re some
  places where assignments occur between hash_T and size_t variables, in
  both directions. Therefore, if we define hash_T to be of a type having
  a different width than that of size_t, we will have an incorrect
  assignment somewhere that will require an assert/guard.  So the most
  sensible option here seems to do hast_T to be size_t too.

- hashtab_T.ht_mask: long_u -> hash_T.

  Masks are used to be combined with hash_T values, so they should be of
  the same type.

hashtab.c:
- hash_may_resize(): oldsize: long_u -> size_t.
- hash_may_resize(): newsize: long_u -> size_t.
- hash_may_resize(): newmask: long_u -> hash_T.
