We split json_invoice(), as it now needs to round-trip to the gossipd,
and uniqueness checks need to happen *after* gossipd replies to avoid
a race.
For every candidate channel gossipd gives us, we check that it's in
state NORMAL (not shutting down, not still waiting for lockin), that
it's connected, and that it has capacity. We then choose one with
probability weighted by excess capacity, so larger channels are more
likely.
As a side effect of this, we can tell if an invoice is unpayble (no
channels have sufficient incoming capacity) or difficuly (no *online*
channels have sufficient capacity), so we add those warnings.

We're about to slow down the invoice rpc (esp. under valgrind), which
breaks the delicate timing of the autocleaninvoice test.
Change that so the autocleaner (and timestamp) starts after the invoices
are added.

We have a lot of infrastructure to delay local channel_updates to
avoid spamming on each peer reconnect; we had to keep tracking of
pending ones though, in case we needed the very latest for sending an
error when failing an HTLC.
Instead, it's far simpler to set the local_disabled flag on a channel
when we disconnect, but only send a disabling channel_update if we
actually fail an HTLC.
Note: handle_channel_update() TAKES update (due to tal_arr_dup), but we
didn't use that before. Now we do, add annotation.

We trade channel_update before channel_announce makes the channel
public, and currently forget them when we finally get the
channel_announce. We should instead apply them, and not rely on
retransmission (which we remove in the next patch!).
This earlier channel_update means test_gossip_jsonrpc triggers too
early, so have that wait for node_announcement.

The help command now adds command usage to its output by calling each
command handler in CMD_USAGE mode.
Instead of seeing, for example:
decodepay
Decode {bolt11}, using {description} if necessary
we see:
decodepay bolt11 [description]
Decode {bolt11}, using {description} if necessary

Incrementing version number means stores which were prior to the previous
commit will be removed, and refreshed. The simplest fix, if not the most
efficient.

There's no reason for the db to ever return non-NULL if it's spent. And there's
only one caller, for which that is definitely true.

We extract the tx from the logs, and then we wait until that hits
the mempool. This is more reliable than 'sendrawtx' in the logs,
which might catch a previous sendrawtx; it's also more explicit
that we expect that tx exactly.

BOLT 7's been updated to split the flags field in `channel_update`
into two: `channel_flags` and `message_flags`. This changeset does the
minimal necessary to get to building with the new flags.
We currently just ignore them. This is one reason the hsm (in some places)
explicitly calls log_broken so we get some idea.
This was the only subdaemon which had a NULL msgcb and msgname, so eliminate
those checks in subd.c.

Got a spurious failure in test_no_fee_estimate; we fired too soon from the logs (presumably
we raced in on the first response, but estimatesmartfee gets called 3 times).

This is a simple reverse proxy that `bitcoin-cli` can talk to when invoked by
`lightningd`. It allows us to trace `bitcoin-cli` calls, and intercept calls to
mock the replies, better than the current bash-script based method.
It's an array: we were only saving the single element; if there was more than
one changed HTLC we'd get a bad signature!
The report in #1907 is probably caused by the other side re-requesting
something we considered already finalized; to avoid this particular error,
we should set the field to NULL if there's no last_sent_commit.
I'm increasingly of the opinion we want to just save all the update
packets to the db and blast them out, instead of doing this
second-guessing dance.

These happen after we compact the store; every log I've seen of a
restart on a real node has a message about truncating the store,
because node_announcements predate channel_announcements.
I extracted one such case from testnet, and reduced it to test here.

1. Wait for a 'sendrawtransaction' *after* the dev-fail message; don't be
fooled by a previous one.
2. Turning on estimate fee sets fees exactly; just wait for it to be processed.
