Remove some orphaned USE macros.

Remove some orphaned USE macros.
    
QXMLQUERY, APPKIT, SAFARI_THEME and IOSURFACE_CANVAS_BACKING_STORE
were never defined. They also belong to other ports so can be safely
removed.

While touching this code, propagated the xmlDocPtr type into
TransformSource from the XMLDocumentParser.

Good catch, will change to xmlDocPtr, which will need to be propagated down from
the XMLDocumentParser.
