This means we do have to set the network correctly though,
and also we can get query messages from lightningd which we have to filter.

It was an obscure dev command, as it never worked reliably.
It would be much easier to re-implement once this is done.
This turned out to reveal a tiny leak on
tests/test_gossip.py::test_gossip_store_load_amount_truncated where we
didn't immedately free chan_ann if it was dangling.

We now have a test blockchain for MCP which has the correct channels,
so this is not needed.
Also fix a benchmark script bug where 'mv "$DIR"/log
"$DIR"/log.old.$$' would fail if you log didn't exist from a previous run.

Save some overhead, plus gets us ready for giving subdaemons direct
store access. This is the first time we *upgrade* the gossip_store,
rather than just discarding.
The downside is that we need to add an extra message after each
channel_announcement, containing the channel capacity.

Some tests require dev support, but the rest can run. We simplify
the gossip_store output so it's the same in non-dev mode too.

It can take a while if bitcoind has the regtest chain, and grossly
distorts our benchmarks!

Channels have a htlc_minimum_msat of 10000, which is why we didn't
find routes.

This doesn't result in a speedup for our benchmark, since we use the

Outputs CSV. We add some stats for load times in developer mode, so we can
easily read them out.
peer_read_all_sec doesn't work, since we seem to reject about half the
updates for having bad signatures. It's also very slow...
routing fails, for unknown reasons, so that failure is ignored in routing_sec.
