Before this patch: 1. connectd says it's connected (peer_connected) 2. we tell connectd we want to talk about each channel (peer_make_active) 3. connectd gives us an fd for each channel, and we connect it to a subd (peer_active) 4. OR, connectd says it sent something about a channel we didn't tell it about, with an fd (peer_active) Now: 1. connectd says it's connected (peer_connected) 2. we start all appropriate subds and tell connectd to what channels/fds (peer_connect_subd). 3. if connectd says it sent something about a channel we didn't tell it about, we either tell it to hang up (peer_final_msg), or connect a new opening daemon (peer_connect_subd). This is the minimal-size patch, which is why we create socket pairs in so many places to use the existing functions. Many cleanups are possible, since the new flow is so simple.
