gossipd: don't send gossip stream, let per-peer daemons read it themselves. Keeping the uintmap ordering all the broadcastable messages is expensive: 130MB for the million-channels project. But now we delete obsolete entries from the store, we can have the per-peer daemons simply read that sequentially and stream the gossip itself. This is the most primitive version, where all gossip is streamed; successive patches will bring back proper handling of timestamp filtering and initial_routing_sync. We add a gossip_state field to track what's happening with our gossip streaming: it's initialized in gossipd, and currently always set, but once we handle timestamps the per-peer daemon may do it when the first filter is sent.

connectd: new daemon to handle connections. This is just copying most of gossipd/gossip.c into connectd/connect.c. It shares the same wire format as gossipd during transition, and changes are deliberately minimal. It also has an additional message 'connect_reconnected' which it sends to the master daemon to tell it to kill a peer; gossipd relied on closing the gossipfd to do this, but connectd doesn't maintain an fd with remote peers.
