    mail-auth: Drop the priv pointer
    
    The current GObject recommendation is to use the generated
    get_instance_private function instead of a separate priv pointer in the
    instance struct. This saves one pointer per class in the hierarchy
    multiplied by the number of instances of the type, and the function is
    fast enough because it only does pointer arithmetic.
