/**
 * Add a new menu item for a stat.
 * This must be called after we've created the main menu, so it can't
 * be called from the routine that registers stats - we have to introduce
 * another per-stat registration routine.
 *
 * @param name the menu label
 *
 * @param group the menu group this stat should be registered to
 *
 * @param callback gets called when the menu item is selected; it should do
 * the work of creating the stat window.
 *
 * @param selected_packet_enabled gets called by set_menus_for_selected_packet();
 * it's passed a pointer to the "frame_data" structure for the current frame,
 * if any, and to the "epan_dissect_t" structure for that frame, if any, and
 * should return TRUE if the stat will work now (which might depend on whether
 * a frame is selected and, if one is, on the frame) and FALSE if not.
 *
 * @param selected_tree_row_enabled gets called by
 * set_menus_for_selected_tree_row(); it's passed a pointer to the
 * "field_info" structure for the currently selected field, if any,
 * and should return TRUE if the stat will work now (which might depend on
 * whether a tree row is selected and, if one is, on the tree row) and
 * FALSE if not.
 *
 * @param callback_data data for callback function
