That was the cause of the bad gossip order failures: gossipd thought our channel was live, but the other end didn't receive message last time. Now gossipd doesn't use fd to kill us (connectd tells master to do so), we can implement read_peer_msg_nogossip(). Fixes: #1706 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
