Matt Corallo 422bdcf814 Never generate a BroadcastChannelUpdate for priv channels ... Currently we always generate a `MessageSendEvent::BroadcastChannelUpdate` when a channel is closed even if the channel is private. Our immediate peers should ignore such messages as they haven't seen a corresponding `channel_announcement`, but we are still giving up some privacy by informing our immediate peers of which channels were ours. Here we split `ChannelManager::get_channel_update` into a `get_channel_update_for_broadcast` and `get_channel_update_for_unicast`. The first is used when we are broadcasting a `channel_update`, allowing us to refuse to do so for private channels. The second is used when failing a payment (in which case the recipient has already shown that they are aware of the channel so no such privacy concerns exist).		2021-07-02 22:21:32 +00:00
