We didn't get the entire thing in the parent when gossipd crashed: stderr
is suitable for these I think.

Failure and pruning were the two places where a node_connection could
be freed; now they both deal with entire channels, we can remove the
NULL checks, and the destructor.

We discarded it; we should populate it. The comment is wrong, since
local_add_channel() doesn't add public channels, and we test that above.

This is twice the 'update_channel_interval' we get handed.
We delete the non-existent channel_add_connection and delete_connection
declarations from the header too.

We currently give them a free pass. The simplest fix is to give them
an old timestamp on initialization.
We still skip unannounced channels, on the assumption that they're
ours. And we set the last_update_timestamp to -1 when we convert to
gossip_getchannels_entry to indicate no update.
This breaks the DEVELOPER=1 pruning test, since we hardcode the 1
week timeout. That's fixed in the next patch.

We make new_routing_channel() populate both connections
(active=false), so local_add_channel becomes simpler. We also
suppress listchannels output of active=false unannounced channels, to
avoid breaking tests (also, these are unusable, so it makes sense to
omit them)
It also seems the logic in add_channel_direction is legacy: a
channel_announce cannot replace the scid (that would be a different
channel), we don't allow duplicate announcements, and the announcement
is never NULL.
And since we disallow repeated channel_announce already, I believe
'forward' is always true, greatly simplifying the logic in
handle_pending_cannouncement.

This makes 'routing_channel' the primary object in the system; it can have
one or two 'node_connection's attached, and points to two nodes.
The nodes are freed when no more routing_channel refer to them. The
routing_channel are freed when they contain no more 'node_connection'.
This fixes#1072 which I surmise was caused by a dangling
routing_channel after pruning.
Each node contains a single array of 'routing_channel's, not one for
each direction. The 'routing_channel' itself orders nodes in key
order (conveniently the index is equal to the direction flag we use),
and 'node_connection' with source in the same order.
There are helpers to assist with common questions like "which
'node_connection' leads out of this node?".
There are now two ways to find a channel:
1. Direct scid lookup via rstate->channels map.
2. Node key lookup, followed by channel traversal.
Several FIXMEs are inserted for where we can now do things more optimally.
Fixes: #1072

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.

I leave all the now-unnecessary accessors in place to avoid churn, but
the use of bitfields has been more pain than help.

I initially disabled this until 0.16 because the withdraw command
was modified to require 'brct1' addresses for regtest.
But commit bd07a9 allows a regular testnet address to work
just as well. So renable this check.
FWIW, the tests without valgrind take 662 seconds before we reduced
the number of blocks, and only 648 seconds now.

0.16.0 is required since we rely on it for some tests and the block
reduction allows us to waste less time during setup. 121 blocks were
chosen so that we have at least one mature output to spend.

Let's have a simple function that allows us to check whether a channel
still has an HTLC open.
