    eap: use G_DEFINE_BOXED_TYPE to simplify code and be thread-safe (rh #979123)
    
    inner_auth_combo_changed_cb():
      model = gtk_combo_box_get_model (GTK_COMBO_BOX (combo));
      gtk_combo_box_get_active_iter (GTK_COMBO_BOX (combo), &iter);
      gtk_tree_model_get (model, &iter, I_METHOD_COLUMN, &eap, -1);
      g_assert (eap);
    
    gtk_combo_box_get_model() failed and thus g_assert (eap) failed as well.
    
    On some circumstances type_id reset 0 in eap_method_get_g_type(). That caused
    g_boxed_type_register_static() to be called again, which resulted in failing
    assertion 'g_type_form_name (name) == 0' and thus eap_method_get_g_type()
    returned 0 instead of proper GType. Later using 0 made gtk_list_store_new()
    fail to get proper GListStore:
    inner_auth_combo_init:
    auth_model = gtk_list_store_new (2, G_TYPE_STRING, eap_method_get_type ())
