  Fix axis traversal from attribute and namespace nodes
  
  When traversing the "preceding" axis from an attribute node, we must
  first go up to the attribute's containing element. Otherwise, text
  children of other attributes could be returned. This made it possible
  to hit a code path in xmlXPathNextAncestor which contained another bug:
  The attribute node was initialized with the context node instead of the
  current node. Normally, this code path is only hit via
  xmlXPathNextAncestorOrSelf in which case the current and context node
  are the same.
  
  The combination of the two bugs could result in an infinite loop, found
  with libFuzzer.
  
  Traversing the "following" and the "preceding" axis from namespace nodes
  should be handled similarly. This wasn't supported at all previously.
