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.
