This lets detect if a node announce preceeds a channel announce once we
delete the node announcement.

And initialize filter (to "never") when we negotiated LOCAL_GOSSIP_QUERIES,
and send initial filter message.

Make the update/announce messages own the element in the broadcast map
not the other way around.
Then we keep a pointer to the message, and when we free it
(eg. channel closed, update replaces it), it gets freed from the
broadcast map automatically.
The result is much nicer!

We currently keep two copies; one in the broadcast structure to send
in order, and one in the routing information. Since we already keep
the broadcast index in the routing information, use that.
Conveniently, a zero index is the same as the old NULL test.
Rename struct node's announcement_idx to node_announce_msgidx to
make it match the other users.

We tal_dup_arr() it, which does take. Make it const in the structure;
the tal_dup_arr() removes the const, so it compiles without it, but it's
misleading.

We only access via index. We do, however, want to clean up when we
delete nodes and channels, so we tie lifetimes to that. This leads
us to put the index into 'struct queued_message'.

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.

We should never be evicting channel_announcements because a) they were
deeply buried and should not change the short_channel_id/tag, b) they
are static.

If channel_announce is rebroadcast, it should replace the existing one
in-place. We currently only do this if we start from the unsigned one
and replace it with the signed one when we hit 6 confirms.
