Substituted all remaining calls to xmlXPathCmpNodes() for

* xpath.c: Substituted all remaining calls to xmlXPathCmpNodes()
  for xmlXPathCmpNodesExt(). Tiny further enhancement of
  xmlXPathCmpNodesExt(). Added additional checks in various code
  parts to avoid calling sorting or merging functions if the
  node-set(s) don't need them; i.e., if they are empty or contain
  just one node.
