 * Add a new menu item for a tap.
 * This must be called after we've created the main menu, so it can't
 * be called from the routine that registers taps - we have to introduce
 * another per-tap registration routine.
 *
 * "callback" gets called when the menu item is selected; it should do
 * the work of creating the tap window.
 *
 * "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 tap will work now (which might depend on whether
 * a frame is selected and, if one is, on the frame) and FALSE if not.
 *
 * "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 tap 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.
