    Fix up signal ordering issues in GtkEntry
    
    Ensure that text and selection boundaries are in a
    consistent state when we emit notifications, that ::insert-text
    and ::delete-text are emitted before any changes, and that
    ::changed is emitted after property notifications when inserting
    or deleting text.
