    Fix leak on SAX1, xmllint --sax1 option and debug
    
    * SAX2.c: don't leak in xmlCheckDefaultedAttributes for standalone
      checking
    * xmllint.c: fix xmllint --sax1 to actually use XML_PARSE_SAX1
    * debugXML.c: don't raise an error if markup wasn't allocated from
      dictionary if document was parsed with option disabling it
