Steven Hawkins resolved TEIID-2601.
-----------------------------------

    Fix Version/s: 8.4.1
                   8.5
       Resolution: Done


Added logic to the logmanger/serialization of lobs to prevent operations that would render a streaming lob invalid.  Also improved the design of connectormanager.

> When the ws translator returns a streamed result internal operations, such as adding to a tuple buffer may attempt to obtain the length, etc. that render the lob unusable and result in opaque errors, such as
> "TEIID30035 Wrong type of data found or no data found; expecting streamable object from the buffer manager"
> We should make streaming best effort (such as resorting to the copy on read logic), more fool-proof with internal operations, or at least improve the error message.
