misc (memleak) fixes:

    added using ndb_end and showing mem allocation stat at exit
    added init of variable
    added destruction of LocalConfig to still memleak
    added delete of theFacade on exit
    stopSessions(true) on socket server to ensure destuction of threads
    added destruction of arbit manager thread
    added true option to stopSessions in transporter facade to ensure destructions of threads
