dev_blackhole_fd was a hack, and doesn't work well now we are async (it worked for sync comms in per-peer daemons, but now we could sneak through a read before we get to the next write). So, make explicit flags and use them. This is much easier now we have all peer comms in one place. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
