Ticket 45 - Upgrade liblfds to 710
    
    Bug Description:  Upgrade from lfds 6 to 710. This fixes many performance and
    other issues.
    
    Fix Description:  Change the make file, referenced headers, and builds to use
    the latest lfds. This is a large change, replacing the entire lfds import
    with lfds710. This also adds a queue abstraction barrier. It exposed issues
    with the tests, so the ns code has now been fixed to properly barrier the state
    machine else we have issues. This also fixes a number of the tests to now handle
    these cases. Finally, because of the upgrade we can now push the stress test
    past 1000 events without crash.
