Rather than have lightningd call us repeatedly to try to connect, have it tell us what peers are transient and aren't, and connectd will automatically try to maintain that connection. There's a new "downgrade_peer" message to tell it a peer is now transient: to make it non-transient we simply tell connectd to connect as a non-transient. The first time, I missed that dual_open_control does its own state transitions :( Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Changelog-Changed: `connectd` now handles maintaining/reconnecting to important peers, and we remember the last successful address we connected to.
