This patch adds support for displaying OPC UA ExtensionObjects. An ExtensionObject is a mechanism to transport user defined structures as serialized blobs. Some types of ExtensionObjects are already defined by the OPC Foundation's OPC UA Specifications. These types can be implemented by this dissector, because they are well-known. Real user-defined or vendor-defined types are unlikely to be implemented by a passive dissector, because this would require browsing of the UA server's address space to retrieve the type information. Currently only the following types are supported: * DataChangeNotification * EventNotification Others OPC defined types will follow. From me: fix warnings: "format not a string literal and no format arguments" svn path=/trunk/; revision=34906
