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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

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&#39;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&#39;s no more &#34;unique_id&#34;: we use the peer id. * For the moment, we don&#39;t ask gossipd when we&#39;re told to list peers, so connected peers without a channel don&#39;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.

struct lightningd;
gossipd: take connectd fd on initialization. connectd has a dedicated fd to gossipd, so it can ask for a new gossip_fd for a peer. gossipd has a standalone routine to create a remote peer (this will eventually be the only way gossipd creates a new peer). For now lightningd creates a socketpair but doesn&#39;t run connectd, so gossipd never sees any requests on this fd. Signed-off-by: Rusty Russell &lt;rusty@rustcorp.com.au&gt;
