	* tests/testmerge.c: Add a checkbox to queue an
	merge/unmerge. Patch from Matthias Clasen.

	* gtk/gtktoolbar.c (struct _GtkToolbarPrivate): Add a new flag
	"need_rebuild"
	(rebuild_menu): New function that rebuilds the overflow menu and
	makes sure it doesn't start or end with a separator.
	(toolbar_content_new_tool_item)
	(toolbar_content_remove)
	(toolbar_content_new_compatibility): Set the rebuild_needed flag
	(gtk_toolbar_size_allocate): Only show the overflow arrow when we
	have actually overflown an item with a proxy menu item. Also make
	sure we rebuild the menu if needed.

	Fix #125504, #142377, #143463

	* gtk/gtkseparatortoolitem.c (gtk_separator_tool_item_expose):
	Obey the "priv->draw" flag. (#143692)
