Massive XPath implementation cleanup:

Browse Source 
- debugXML.c testXPath.c xpath.[ch]: got pissed by some nastyness
  in the XPath engine, rewrote large parts of it, now it's far
  cleaner and in sync with the REC not an old WD. Fixed a parsing
  problem in the interactive XML shell found when testing XPath.
