connectd/peer_exchange_initmsg: handle peer comms ourselves. connectd is the only user of the cryptomsg async APIs; better to open-code it here. We need to expose a little from cryptomsg(), but we remove the 'struct peer' entirely from connectd. One trick is that we still need to defer telling lightningd when a peer reconnects (until it tells us the old one is disconnected). So now we generate the message for lightningd and send it once we're woken. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

connectd: Pass the init_featurebits down to connectd and use in init The `init_featurebits` are computed at startup, and then cached indefinitely. They are then used whenever a new `init` handshake is performed. We could add a new message to push updates to `connectd` whenever a plugin is added or removed, but that's up for discussion.

Use node_id everywhere for nodes. I tried to just do gossipd, but it was uncontainable, so this ended up being a complete sweep. We didn't get much space saving in gossipd, even though we should save 24 bytes per node. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
