Prior to this patch update, we expected a client to call `openchannel_signed` before checking for peer's tx-sigs messages on the wire. When moving to a 'multifundchannel' approach, we'll need to be able to collect sigs from our peers before sending our tx_sigs message. There's no strict ordering on when tx-sigs messages are sent/received, so this is fine. To do this, we go ahead and start up channeld as soon as commitment_sigs are secured, so that we process incoming tx-sigs from our peers as soon as we get them.
