be5d945e97 gossip: only send out gossip to non-local peers when we're supposed to.
This hook is called when the queue is empty; we should only send gossip
according to the gossip timer.  We're currently dribbling it out after
every message, in violation of the spec.

a073c201e0 gossip: expose and use get_node() helper.
It's a trivial helper function from routing.c, but let's expose it
and use it in gossip.c too.

5970890fae gossipd: use status levels for unusual reporting.
Now we have them, let's use them.  I missed one case deliberately, since
that causes merge conflicts when I replace it in a following patch.

60e20b502e gossipd: simplify pruning code.
If we make destroy_node() remove itself from the map, then we simply
need to free it.

We can batch the frees (as we need) simply by reparenting all the pruned
nodes onto a single temporary parent, then freeing it, relying on tal's
internal datastructures.

e76a0b4ddc gossipd: fix race where we can handoff peer with bad cryptostate.
DEBUG:root:lightningd(16333): 2018-02-08T02:12:21.158Z lightningd(8262): lightning_openingd(0382ce59ebf18be7d84677c2e35f23294b9992ceca95491fcf8a56c6cb2d9de199): Failed hdr decrypt with rn=2

We only hand off the peer if we've not started writing, but that was
insufficient: we increment the sn twice on encrypting packet, so there's
a window before we've actually started writing where this is now
wrong.

The simplest fix is only to hand off from master when we've just written,
and have the read-packet path simply wake the write-packet path.

d5effcb961 test_lightning: fix race on testing, esp. test_closing_different_fees.
We get intermittant failure: WIRE_UNKNOWN_NEXT_PEER (First peer not ready)
because CHANNELD_NORMAL and actually telling gossipd that the channel
is available are distinct things: we need both.

(For test_closing_different_fees, we were testing CHANNELD_NORMAL on
the peer, not on l1, too).

But we may also directly send the announcement sigs if the height is
sufficient, so the simplest is to unify the messages.

db30411ba5 gossipd: look up short_channel_id when we see a channel_announcement.
This is done it two parts, since we have to ask the main daemon to do
the lookup for us.

If this becomes a bottleneck, we can have a separate daemon, or even
an RPC pipe to bitcoind ourselves.

0f97b8cf36 subdaemon.c: subdaemon_setup() routine for all daemons.
Our handling of SIGPIPE was incoherent and inconsistent, and we had much
cut & paste between the daemons.  They should *ALL* ignore SIGPIPE, and
much of the rest of the boilerplate can be shared, so should be.
