Add a TextView reftests checking border-windows TextView border windows are internal windows used to draw on the gutter of the textview (e.g. line numbers). The test uses the gmodule hook to programmatically draw on the border-windows at each side of the textview and compares the result with 3x3 grid of labels.

textview: use GtkTextViewChild for border and overlay children This creates a new GtkTextViewChild that can manage overlay children at given x,y offsets in buffer coordinates. This simplifies GtkTextView by extracting this from GtkTextWindow as well as providing a real widget for the borders. With this change, we also rename gtk_text_view_add_child_in_window() to gtk_text_view_add_overlay(). For those that were using GTK_TEXT_WINDOW_WIDGET, they can use a GtkOverlay. It does not appear that anyone was using GTK_TEXT_WINDOW_(LEFT|RIGHT|TOP|BOTTOM) for widgets in this fashion, but that can be done by setting a gutter widget with gtk_text_view_set_gutter(). We can make GtkTextViewChild public if necessary to simplify this should it become necessary. GtkTextViewChild will setup a CSS node of either "text" or "border" depending on the GtkTextWindowType. The old GtkTextViewChild has been renamed to AnchoredChild as it is only used for widgets with anchors in the GtkTextBuffer. This also removes the use of allocated GSList and instead embeds a GQueue and GList to save a few extraneous allocations.
