XmlFilterAdaptor: use the fastparser API when possible
part of the process of making SvXMLImport fastparser-only Which uncovered several bugs because I end up stacking fast and slow parsers, not once, but twice. Specifically, we have a problem here with default namespaces e.g. <math xmlns="http://www.w3.org/1998/Math/MathML" display="block"> <semantics><mrow><mstyle mathsize="12pt"> where going from slow- to fast- parser loses this information, because there is no way to represent this in the fastparser world, so we end up with nastiness when we transition back to slow-parser, and then back-again to fast-parser. So I fixed a couple of places XMLEmbeddedObjectImportContext and in SvXMLLegacyToFastDocHandler, and then worked around some of it by introducing an new XImporter2 interface so I could strip out out one of the slowparser -> fastparser transitions.
