listview: Add skeleton
The widget doesn't do very much yet. But at least it prints lots of
"Hello world".

+ * @title: GtkListView
+ * @short_description: A widget which displays a list of items
+ *
+ * #GtkListView provides a view on a #GtkTreeModel that is not based on cell
+ * renderers. It displays the model as a list of regular #GtkWidgets instead.
+ *
+ * Like #GtkTreeView or #GtkIconView, it allows to select one or multiple items
+ * (depending on the selection mode, see gtk_list_view_set_selection_mode()).
+ * In addition to selection with the arrow keys, #GtkListView supports
+ * rubberband selection, which is controlled by dragging the pointer.
+ *
+ * Note that if the tree model is backed by an actual tree store (as
+ * opposed to a flat list where the mapping to lists is obvious),
+ * #GtkListView will only display the first level of the tree and
+ * ignore the tree's branches.
+ *
+ * Since: 3.6
