The One Big API is confusing, and has enough corner cases that we should ditch it rather than add more. See: https://www.sandimetz.com/blog/2016/1/20/the-wrong-abstraction In particular, when openingd is changed to chat to peers even when it's not actively opening a channel, it wants to handle (most) errors by continuing, not calling peer_failed(). This exposes the constituent parts. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
