Steven Hawkins resolved TEIID-771.
----------------------------------

    Resolution: Done

Updated tuplesourceinfo to hold references to contained lobs and to track persistent streams via their containing lob - when it's gc'ed then the tuplesource will be removed (if not already removed by a connection close).

> Lob handling in the buffermanager relies upon overloading the notion of tuple source group and on reassigning the streamable obejcts to the latest tuple source / group.  However it's possible for the same streamable object to be associated with multiple tuple sources.   Callers should not be forced to handle invalidreferenceexceptions, since implementors of udf, or even internal code, will fail without explicit handling.
