Now the flow is much simpler from a lightningd POV: 1. If we want to connect to a peer, just send gossipd `gossipctl_reach_peer`. 2. Every new peer, gossipd hands up to lightningd, with global/local features and the peer fd and a gossip fd using `gossip_peer_connected` 3. If lightningd doesn't want it, it just hands the peerfd and global/local features back to gossipd using `gossipctl_handle_peer` 4. If a peer sends a non-gossip msg (eg `open_channel`) the gossipd sends it up using `gossip_peer_nongossip`. 5. If lightningd wants to fund a channel, it simply calls `release_channel`. Notes: * There's no more "unique_id": we use the peer id. * For the moment, we don't ask gossipd when we're told to list peers, so connected peers without a channel don't appear in the JSON getpeers API. * We add a `gossipctl_peer_addrhint` for the moment, so you can connect to a specific ip/port, but using other sources is a TODO. * We now (correctly) only give up on reaching a peer after we exchange init messages, which changes the test_disconnect case.
