Changelog-Fixed: pay: Fixed a bug where routehints would be ignored if the payment exceeded 10,000 satoshi. This is particularly bad if the payee is only reachable via routehints in an invoice.
It's not all that rare to do these operations, and requiring annotations
for it is a little painful.

Changelog-Added: New option `--important-plugin` loads a plugin is so important that if it dies, `lightningd` will exit rather than continue. You can still `--disable-plugin` it, however, which trumps `--important-plugin` and it will not be started at all.
We were basing the 2016 block timeout on the blockchain height that we had
processed at the time completed the funding, which could lag considerably
behind the network-wide blockheight. For example this could happen if we
started with `--rescan` from a low height, taking some time to catch up.
This means that we could end up forgetting channels even before reaching the
network blockheight. This patch instead uses the headercount reported by the
backend plugin if we aren't caught up yet. While the chances of this happening
are still there, the window it might happen are much reduced, since headers
can be synced in a couple of minutes.

Changelog-Changed: Funding timeout is now based on the header count reported by the bitcoin backend instead of our current blockheight which might be lower.
Arguably a low-priority bug since no current node ever generates routehints longer
than one hop.
However, it is possible as an edge case, if the destination is directly accessible
*and* supports multiple channels, that we route through the destination, one of the
*other* channels it has not in the routehint, to the entry point, and then through
the routehint.
This change removes the risk of the above edge case.
Changelog-None: arguably a low-priority bug.
We've had problems with blocksonly in the past and bitcoind still allows
to use outdated (thus potentially dangerous estimates) while running
bitcoin with -blocksonly.
ZmnSCPxj mentionned that we still don't document this, but i figured
that in this specific case an explicit check and error seems preferable.
Changelog-Added: We now explicitly check at startup that our default Bitcoin backend (bitcoind) does relay transactions.

This allows us to kill two birds with one stone: once connected, we use
the output of the successful call to do some sanity checks (only
checking the version for now, but more are yet to come!).

We'd previously take the failed attempt and estimate the failing channel's
capacity at 3/4 of the attempted amount, which is rather aggressive. This
reduces this aggressiveness to use the exact amount tried, but excluding on
equality. This still skips attempting the same route with the same amount, but
also permits attempts that are in the range [3/4, 1] of the failed attempt
amount to still be attempted.
Changelog-Changed: JSON-RPC: `delinvoice` will now report specific error codes: 905 for failing to find the invoice, 906 for the invoice status not matching the parameter.
the way we use PSBTs to sign things requires that we have the
scriptpubkey available on the utxo so we can populate the witness-utxo
field with it.
this causes problems if we don't already have the scriptpubkey cached in
the database, as in *some* cases we require a round trip to the HSM to
populate them
to get over this hump, we backfill any and all missing scriptpubkey
information for the utxo's that we hold in our wallet.
this will allow us to clean up the NULL handling of missing
scriptpubkeys.
we're about to add a migration that requires access to the bip32_key
in order to calculate missing scriptpubkeys.
prior to this patch, we don't have access to the bip32 key in the db
migration, as it's set on the wallet but after the db migrations are
run.
here we patch it through so that every migration can access it
```
# Excludes channel, then ignores routehint which includes that, then
# it excludes other channel.
> assert len(status) == 2
E assert 1 == 2
E -1
E +2
```
The invoice we use at the end has a routehint: 50% of the time it's
to l2 (which fails), 50% to l5 (which succeeds).
Change it to create invoice before channel with l5 so it does the
retry like we expect here.

We sum up the amounts just like we do with `amount_sent`, however we may have
parts that don't have that annotation, so make it optional.
Suggested-by: Rusty Russell <@rustyrussell>
While not directly necessary, it still feeds the `listpays` result, and so we
should pass it along if we can, so we don't have to rely solely on the
`amount_sent` field, which includes the fees.

Since we started using `sendonion` in the `pay` plugin we no longer
automatically have the `amount` annotation on (partial) payments. This
replicates the issue so we can fix it.
Reported-by: Rusty Russell <@rustyrussell>
There were no channel updates in my log; because sendonion doesn't know the
actual node_ids or channel_ids, we can't tell gossipd what node/channel it was
so it can no longer remove them on PERM errors.
However, we can tell it the error message so it can apply the update.

Changelog-Added: JSON-RPC: `sendonion` has a new optional `bolt11` argument for when it's used to pay an invoice.
