Remove fatalErrorHandler()
Remove fatalErrorHandler()

According to libxml2 documentation:
http://xmlsoft.org/html/libxml-tree.html#xmlSAXHandler
http://xmlsoft.org/html/libxml-parser.html#fatalErrorSAXFunc
.. the SAX fatalError callback is unused; error gets all the errors. Use
normalErrorHandler for both the error and fatalError callbacks and remove
fatalErrorHandler().
