  Improve XPath predicate and filter evaluation
  
  Consolidate code paths evaluating XPath predicates and filters.
  
  Don't push context node on stack when evaluating predicates. I have no
  idea why this was done. It seems completely useless and trying to pop
  the context node from a corrupted stack has already caused security
  issues.
  
  Filter nodesets in-place and don't create node sets with NULL gaps which
  allows to simplify merging a great deal. Simply move matched nodes
  backward and create a compact node set.
  
  Merge xmlXPathCompOpEvalPositionalPredicate into
  xmlXPathCompOpEvalPredicate.
