Changes that add support for the DDX response. I've based this on Nathan Potter's work in the Java DAP software. At this point the code can produce a DDX from a DDS and it can merge attributes from a DAS into a DDS to produce a DDX fully loaded with attributes. Attribute aliases are not supported yet. I've also removed all traces of strstream in favor of stringstream. This code should no longer generate warnings about the use of deprecated headers.
