Adapts the `test_forward_stats` test to include checks for the
`forwarded_payments` table. Will add checks for the `listforwardings`
RPC call next.

When the wrong key is used, the remote end simply hangs up.
We used to get a random errno, which tends to be "Operation now in progress."
Now it's defined to be 0, detect and provide a better error.

Have c-lightning nodes send out the largest value for
`htlc_maximum_msat` that makes sense, ie the lesser of
the peer's max_inflight_htlc value or the total channel
capacity minus the total channel reserve.
We don't create unannouncable channels, but other implementations can.
Not only is it rude to expose these via invoices, it's probably not
useable anyway.

There is an issue with the way we retrieve the channel accounting info
that will result in always showing 0 for all stats. This tests for it
and the next commit will fix it.
During tests, this is half our log! And Travis truncates it if we get
a failure in test_restart_many_payments.
Interestingly, test_logging had a bug which relied on this spam :)

We don't save them to the database, so fix things up as we load them.
Next patch will actually save them into the db, and this will become
COMPAT code.
Also: call htlc_in_check() with NULL on db load, as otherwise it aborts
internally.

Usually, we only close an incoming HTLC once the outgoing HTLC is completely
resolved. However, we short-cut this in the FULFILL case: we have the
preimage, so might as well use it immediately (in fact, we wait for it to
be committed, but we don't need to in theory).
As a side-effect of this, our assumption that every outgoing HTLC has
a corresponding incoming HTLC is incorrect, and this test (xfail) tickles
that corner case.

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

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.
