Use the new QTextCodec api in the QXmlStreamWriter.

Instead of accesing private data, use the QTextCodec::makeEncoder() to pass the
initial conversion flags to the codec.

Also improved the behavior - we shouldn't add BOM in the middle of the data
when dumping xml in all encodings, not only for utf8.
