Use long_natural_t for recnum_t
For 64 bits, device operations will provide an addressing space of 64
bits.
Also define the translation functions if long_natural_t or
long_integer_t are ever used in RPCs.
Note that MIG does not implicitly inherit the translation functions from
types hence the need to redefine them for recnum_t.
