	* XmlAttribute.cs,
	  XmlElement.cs : Fixed CloneNode() for bug #46129.
	* XmlDocument.cs : Fixed MakeReaderErrorMessage that specified invalid
	  String.Format arguments, and basically XmlException.ctor(
	  IXmlLineInfo, message) seems good idea to use.
	* XmlTextReader.cs :
	  - Fixed .ctor(Stream, XmlNodeType, XmlParserContext) which had
	    required non-null context which don't have to exist.
	  - Added state check. Introduced 'currentState' and 'maybeTextDecl'
	    (for external entity) and removed hasEnteredDocument. Added
	    state-check logic to ReadStartTag(), ReadEndTag(), ReadText(),
	    ReadCData(), ReadDoctypeDecl() and ReadWhitespace().
	  - Replaced throw ReaderError() with throw new XmlException() and
	    fixed that some error hadn't thrown, only created.
	  - ResetState() should re-initialize existing private members other
	    than some specified fields.
	  - Private AddAttribute() should check if the same-named attribute
	    already exists.
	* DTDObjectModel.cs : Additive declaration for ATTLIST is availabe now.
