XPACleanup - release reserved XPA memory

       When XPA is initialized, it allocates a small amount of memory for the access control list, temp
       directory path, and reserved commands. This memory is found by valgrind to be "still reachable", meaning
       that "your program didn't free some memory it could have". Calling the XPACleanup() routine before
       exiting the program will free this memory and make valgrind happy.
