When we want to do Polkit authentication we want to temporarily pause handling of a method call until we have the Polkit reply, and then start again. Let's add some glue to make that easy. This adds two helpers: varlink_dispatch_again() allows to ask for redispatching of the currently queued incoming message. Usecase is this: if we don't process a methd right away, we can come back later, and ask it to be processed again with this function, in which case our handlers will be called a 2nd time, exactly like on the first time. varlink_get_current_message() provides access to the currently processed method call. With this the polkit logic can look into the current message, do its thing, and then restart the method handling.
