We can have more than one; eg we might offer both bech32 and a p2sh
address, and in future we might offer v1 segwit, etc.

There are two very hard problems in software engineering:
1. Off-by-one errors
In this case we were rolling back further than needed and we were starting the
catchup one block further than expected.

I saw a failure in test_funding_fail():
assert l2.rpc.listpeers()['peers'][0]['connected']
This can happen if l2 hasn't yet handed back to gossipd. Turns out
we didn't mark uncommitted channels as connected:
[{'id': '03afa3c78bb39217feb8aac308852e6383d59409839c2b91955b2d992421f4a41e', 'connected': False, 'channels': [{'state': 'OPENINGD', 'owner': 'lightning_openingd', 'funder': 'REMOTE', 'status': ['Incoming channel: accepted, now waiting for them to create funding tx']}]}]

This is probably covered by our "channel capacity" heuristic which
requires the channel be significant, but best to be explicit and sure.

So we know how much counterparty could theoretically steal from us
(msatoshi_to_us - msatoshi_to_us_min) and how much we could
theoretically steal from counterparty (msatoshi_to_us_max -
msatoshi_to_us).
For more piloting goodness.
In particular, the main daemon and subdaemons share the backtrace code,
with hooks for logging.
The daemon hook inserts the io_poll override, which means we no longer
need io_debug.[ch]. Though most daemons don't need it, they still link
against ccan/io, so it's harmess (suggested by @ZmnSCPxj).
This was tested manually to make sure we get backtraces still.

I didn't convert all tests: they can still use a standalone context.
It's just marginally more efficient to share the libwally one for all
our daemons which link against it anyway.

If we only remember the actions that added channels then we'd restore them when
re-reading the gossip_store, so put a tombstone in there to remember to delete
it. These will be cleared upon re-writing the store since the announcements wont
be written anymore.

This is necessary since we have onchaind tell us about the
their_unilateral/to_us output, after it is already in a block.

We don't handle \u, since we assume everyone sane is using UTF-8. We'd
still have to reject '\u0000' and maybe other weird cases if we did.

Since we may want to extend the on-disk format by adding custom information we
may as well just go the extra mile and reuse the serialization primitives we
already have.

But only if we're actually going to change the feerate, otherwise we'd
log every time.
