The callback-based method of listing remote references dates back to the beginning of the network code's lifetime, when we didn't know any better. We need to keep the list around for update_tips() after disconnect() so let's make use of this to simply give the user a pointer to the array so they can write straightforward code instead of having to go through a callback.
