This doesn't seem to be the right place. Move this to where ObjectProxyTable is
defined above. Besides, encoding the options at the end of the string isn't the
best thing we can do. see my comment elsewhere.

Woops, this was meant to go above.  I've updated the type and comment as
requested.

   typedef std::map<std::string,
                    scoped_refptr<dbus::ExportedObject> > ExportedObjectTable;
   ExportedObjectTable exported_object_table_;
