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.

We actually intercept the gossip_timestamp_filter, so the gossip_store
mechanism inside the per-peer daemon never kicks off for normal connections.
The gossipwith tool doesn't set OPT_GOSSIP_QUERIES, so it gets both, but
that only effects one place.

channeld can't do it any more: it's using local sockets. Connectd
can do it, and simply does it by type.
Amazingly, on my machine the timing change *always* caused
test_channel_receivable() to fail, due to a latent race.

As connectd handles more packets itself, or diverts them to/from gossipd,
it's the only place we can implement the dev_disconnect logic.

We temporarily hack to sync_crypto_write/sync_crypto_read functions to
not do any crypto, and do it all in connectd.

Instead of passing the incoming socket to lightningd for the
subdaemon, create a new one and simply shuffle data between them,
keeping connectd in the loop.
For the moment, we don't decrypt at all, just shuffle. This means our
buffer code is kind of a hack, but that goes away once we start
actually decrypting and understanding message boundaries.
This implementation is naive: it closes the socket to the local daemon
as soon as the peer closes the socket to us. This is fixed in a
successive patch series (along with many other similar issues).
