Rusty Russell 92d66a5451 gossipd: take connectd fd on initialization.
connectd has a dedicated fd to gossipd, so it can ask for a new gossip_fd
for a peer.

gossipd has a standalone routine to create a remote peer (this will
eventually be the only way gossipd creates a new peer).

For now lightningd creates a socketpair but doesn't run connectd, so
gossipd never sees any requests on this fd.

Rusty Russell e1dfb1b178 gossipd: simplify per-peer features.
Store the two we care about as booleans.  Once connectd is complete we won't
even have the feature bitmaps for peers.

Rusty Russell b4ed954435 connectd: do socket binding during initial setup.
gossipd does a two-step initialization: it only tries to create the
listening sockets when it's activated.  This means it doesn't know the
addresses to announce until this point.

Now connectd is doing this, this would mean we'd have to tell gossipd
later ("oh, BTW here are your addresses") since we need to start gossipd
before connectd activation.

So make connectd do all the setup, but only actually listen on the fds
once we activate it.  We clone the gossip_init message into
connect_wire.csv.  The master daemon still waits for a reply from
connectd for the activate message, since it wants to be listening
before it prints "Server started".

Rusty Russell eab83ca79b connectd: new daemon to handle connections.
This is just copying most of gossipd/gossip.c into connectd/connect.c.
It shares the same wire format as gossipd during transition, and changes
are deliberately minimal.

It also has an additional message 'connect_reconnected' which it sends
to the master daemon to tell it to kill a peer; gossipd relied on
closing the gossipfd to do this, but connectd doesn't maintain an fd
with remote peers.

Rusty Russell f4e2a9c921 pytest: don't expect alias and color in listpeers.
Gossipd combines the information if it knows it, but that's really the

this information.

This will be used by onchaind for now, but also for openingd and channeld

has handed out the revocation secret previously!

I saw an error in test_gossip_weirdalias in Travis, where listnodes(nodeid)
