gas hash.h tidy
Only inline functions should be defined in hash.h, there's no benefit in having multiple copies of hash_string_tuple and eq_string_tuple. Also, use the table alloc_f when allocating tuples to be stored, so that these functions are usable with different memory allocation strategies. * hash.h (struct string_tuple, string_tuple_t): Move earlier. (string_tuple_alloc): Add table param, allocate using table alloc_f. (str_hash_insert): Adjust to suit. Call table->free_f when entry is not used. (hash_string_tuple, eq_string_tuple): Move to.. * hash.c: ..here.
