John Wiegley d86a91d45b The new XPath parser has been integrated, although I have removed the 
XML-related bits -- I just wanted the better infrastructure that had been
created during the rewrite.  It doesn't work, but it compiles and links now.
This means that all of the previous 3.0 code has been moved over, although
there are still snippets of code in pending/old that need to be restored.
