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.

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.

In preparation for removing in-memory invoice objects.
Since they will be removed, there will no longer be any
individual invoice objects to attach to.
The following command can be used to trigger these messages:
```
$ timeout 0.01 cli/lightning-cli connect [insert-syntactically-valid-peer-id-here] 123.123.123.123 # where 123.123.123.123 is unreachable
```
This is how the error before the fix looked like on Arch Linux with
GNU libtool 2.4.6.40-6ca5-dirty:
$ make installcheck
...

Then there was linking error which needed to be fixed by correcting
the idea of installing external libraries to a particular directory.
If bitcoind is still fetching blocks, we might accidentally inject
the failure between getblockhash and getblock. That's OK, but
it's not the failure we test for.
