This patch guts gossipd of all peer-related functionality, and hands
all the peer-related requests to channeld instead.
gossipd now gets the final announcable addresses in its init msg, since
it doesn't handle socket binding any more.
lightningd now actually starts connectd, and activates it. The init
messages for both gossipd and connectd still contain redundant fields
which need cleaning up.
There are shims to handle the fact that connectd's wire messages are
still (mostly) gossipd messages.

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".

This still has a problem, but we can't fix that easily here; per-peer
daemons don't have this trouble, however.

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.
