Rusty Russell	474887512d	gossipd: rewrite to do the handshake internally. 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.

gossipd: rewrite to do the handshake internally.

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.

lightningd/lightningd: wire up lightningd_gossip.

Now we hand peers off to the gossip daemon, to do the INIT handshake and
re-transmit/receive gossip.  They may stay there forever if neither we nor
them wants to open a channel.
