sure the output has no unescaped "%"s. (For wrapping printf-style
	unmanaged methods with String.Format-style managed ones.)

	* gtk/MessageDialog.custom (MessageDialog): use it. #71405. Also,
	use gtk_message_dialog_new_with_markup by default, and add an
	overloaded ctor that lets you use the non-markup version.

	* gtk/Gtk.metadata: hide the GtkMessageDialog ctors so we don't

	* sample/GtkDemo/DemoApplicationWindow.cs:
	* sample/GtkDemo/DemoDialog.cs: simplify the MessageDialog usage;
	don't need to call String.Format separately now.

<remarks>This is a wrapper for marshalling between managed String.Format-style methods and unmanaged printf-style ones. The managed function should take a <see cref="T:System.String" /> format, and a <see langword="params" /> array of <see cref="T:System.Object" />, and pass that to <see cref="M:GLib.Marshaller.StringFormat" />. <see cref="M:GLib.Marshaller.StringFormat" /> will format the data, and then make sure that any percent signs in the result are doubled so that they can safely be passed to an unmanaged method that expects a printf-style string (and following arguments).</remarks>
