We're going to make it a first-class citizen, and pending routing_channel
are not real ones (in particular, we don't want to create pending nodes).
We had a linked list called rstate->pending_cannouncement which we didn't
actually use, so put that back for now and add a FIXME to use a faster
data structure.
We need to check that list now in handle_channel_update, but we never
have a real routing_channel and a pending, unless the routing_channel
isn't public.

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.

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.

I'm not completely conviced that we can't end up removing pending things,
so change asserts to simple returns.

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.

get_connection_by_scid() and update_to_pending() both do the same
lookup which we did in handle_channel_update().
Do the lookup once, and simplify the others.

We always hand in "NULL" (which means use tal_len on the msg), except
for two places which do that manually for no good reason.

We usually did this, but sometimes they were named after what they did,
rather than what they cleaned up.
There are still a few exceptions:
1. I didn't bother creating destroy_xxx wrappers for htable routines
which already existed.
2. Sometimes destructors really are used for side-effects (eg. to simply
mark that something was freed): these are clearer with boutique names.
3. Generally destructors are static, but they don't need to be: in some
cases we attach a destructor then remove it later, or only attach
to *some* cases. These are best with qualifiers in the destroy_<type>
name.

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.

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.

Now we have wirestring, this is much more natural. And with the
24M length limit, we needn't be so concerned about dumping 64k peer
messages in hex.

These are now logically arrays of pointers. This is much more natural,
and gets rid of the horrible utxo array converters.

Commit a57a2dcb86 introduced a time_t
in routing.h. So also move the time.h include to the header. This
fixes the build on FreeBSD.

We were dropping these on the floor while checking for txout. So now
we add a map that holds announcements while we are checking.

We are wasting way too much time looking for announcements and updates
in the broadcast. We can just hint where to find the message to be
evicted and safe the traversal.
