We use these for receiving arrays at init time, we should also use them
for fulfull/fail of HTLCs in normal operation. That we we benefit from all
those assertions.

There are three cases:
1. failcode is 0, scid is NULL, failreason is the onion to fwd.
2. failcode is non-zero, but UPDATE bit not set. scid is NULL, failreason NULL.
3. failcode has UPDATE bit set. scid is non-NULL, failreason is NULL.
Assert these on marshaling, and only send the parts we need so unmarshal is
always canonical.

The master tells us the short_channel_id of the outgoing channel, and
channeld is supposed to get the corresponding channel_update from gossipd.
Instead, it got the channel_update for the *local* channel and ignored
that one.
The master tells us the short_channel_id of the outgoing channel when
failing an HTLC, but channeld didn't store it anywhere. It also
didn't tell channeld the short_channel_id in the case where we're
reconnecting and it's feeding us an array of failed htlcs.

We delay internally to reduce broadcastig route flap, but errors are
a special case: we want to send the latest, otherwise we might send an
old (non-disabled) update.

We used to just manually set ROUTING_FLAGS_DISABLED, but that means we
then suppressed the real channel_update because we thought it was a
duplicate!
So use a local flag: set it for the channel when the peer disconnects,
and clear it when channeld sends a local update.

We were *supposed* to be waiting for the next commitment tx so we
made sure the one we broadcast was old, *but* the 'revoke_and_ack'
we were waiting for could be matched by the completion of the previous
'revoke_and_ack'.

This needs to be done separately from the rest of the daemon since we can
otherwise not make sure that it happens before the DB is freed and we might
still need the DN, and be running in a DB transaction, for some destructors to
run.
We were failing test_closing_torture, with gossipd complaining that it
received a malformed packet. This makes it pass, but the real fix is
in the next series.

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

gossip_getnodes_entry was used by gossipd for reporting nodes, and for
reporting peers. But the local_features field is only available for peers,
and most other fields are only available from node_announcement.
Note that the connectd change actually means we get less information
about peers: gossipd used to do the node lookup for peers and include the
node_announcement information if it had it.
Since generate_wire.py can't create arrays-of-arrays, we add a 'struct
peer_features' to encapsulate the two feature arrays for each peer, and
for convenience we add it to lightningd/gossip_msg.

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.

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.

Store the two we care about as booleans. Once connectd is complete we won't
even have the feature bitmaps for peers.

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.

Gossipd combines the information if it knows it, but that's really the
job of 'listnodes'. More importantly, channeld won't have access to
this information.

For now we still derive it, too, and assert it's correct.
