    Fix for [TRAFODION-2091] Lobglobals and hdfsFS handle  fix

    hdfsFS handling is now done at the Context level and is maintained as  hashqueue for each
hdfsPort/hdfsSever combination.
    The first time a component connects, it checks thae global list, if the handle is not
found a new entry is created and added to the list.
    All calls to individual callers making hdfs Disconnect calls are removed since they affect
other components usage of hdfs API. 
    Cleanup in how LobGlobals are allocated and maintained. They are part of ex_globals and
TCBs get a pointer to the ExLobGlobals when they need to use the LOB interface.
    Fixed dataModCheck and emptyDirectory to change how lobGlobals initialization happens.
