* xmlwriter.c include/libxml/xmlwriter.h doc/* : applied patch from
  Alfred Mickautsch for better DTD support.
* SAX2.c HTMLparser.c parser.c xinclude.c xmllint.c xmlreader.c
  xmlschemas.c: fixed bug #137867 i.e. fixed properly the way
  reference counting is handled in the XML parser which had the
  side effect of removing a lot of hazardous cruft added to try
  to fix the problems associated as they popped up.
* xmlIO.c: FILE * close fixup for stderr/stdout
