bug report #0036882: [Feature] Class and record definition XML dump extension

  These patches extend the node dump feature (enabled with DEBUG_NODE_XML)
  so it also dumps class and record definitions to the XML file. They are contained within <definition> tags.
  Currently only fields and constants are dumped to the XML file. Methods, constant and variable definitions may be added later.
