Some memory-handling fixes

Free the correct bits of datum, not bits that have already been set to
NULL, after getting query results back (both in the command-line binary
and in the PD external).

In the external, free the results structure once the data has been
passed into the outlets.

   A C-program for MT19937, with initialization improved 2002/1/26.
   Coded by Takuji Nishimura and Makoto Matsumoto.

   Before using, initialize the state by using init_genrand(seed)  
   or init_by_array(init_key, key_length).
