The code was generating a char ** of string representations of the ks_tuple() array but it was not using it. We modify the code to: 1. extend the array returned by ks_tuple2str() to include enough space for the trailing NULL and ensure that there is a NULL at the end, 2. not free the array before exiting ks_tuple2str() as we intend to use it in the caller, 3. re-organise the pointers in hdb_generate_key_set() to make it more clear how we are to free things that have been allocated. 4. free the char ** given us by ks_tuple2str() if it has been allocated.
