FIXES 15585

 * use new rx_GetConnection/rx_PutConnection functions to increment/
   decrement the refCounts on the rx_connection objects so that the
   objects are not invalidated during RXAFS_xxx calls when:

    - the user tokens change
    - the global cryptlevel changes

 * import SysName from registry and parse along white space boundaries
