While tests are working this merge unfortunately reintroduced a bug in
handling extension-objects.
merge generate_namespace finished but namespace broken

Example: asked for node with nodeId={i=2256}, got node with
nodeId={i=3168},BrowseName= {Length=13, Data=AddNodesCount}
added some namespace tests and found out that nsid matters

never believe in comments...
added another behaviour specification to namespace tests

and found another error in the handling of Strings in xml2ns0 - length
seems to be not set correctly under all circumstances
shall iterate visit empty slots?

@jpfr: please check if the coded specifications on iterations over the
namespace meet your intentions
