Anchor outputs break many assumptions in our tests:
1. Remove some hardcoded numbers in favor of a fee calc, so we only have to
change in one place.
FIXME: This should also be done for elements!
2. Do binary search to get feerate for a given closing fee.
3. Don't assume output #0: anchor outputs perturb them.
4. Don't assume we can make 1ksat channels (anchors cost 660 sats!).

Changelog-Fixed: pay: Correct a case where we put the sub-payment value instead of the *total* value in the `total_msat` field of a multi-part payment.
The worst effect is that unpublished nodes are harder to pay, but
even published ones make us do unnecessary work, since we are
losing routehints from the published ones that could help us
actually route better to them.
On my test machine, we queried bitcoind before the close tx was sent:
```
# When output is spent, it should give us null !
txo = l1.rpc.call("getutxout", {"txid": txid, "vout": 0})
> assert txo["amount"] is txo["script"] is None

listpays: make doc-all missed
Changelog-Added: JSON-RPC: `listpays` can be used to query payments using the `payment_hash`
Changelog-Added: JSON-RPC: `listpays` now includes the `payment_hash`
And when it's set, and we're SLOW_MACHINE, simply disable valgrind.
Since Travis (SLOW_MACHINE=1) only does VALGRIND=1 DEVELOPER=1 tests,
and VALGRIND=0 DEVELOPER=0 tests, it was missing tests which needed
DEVELOPER and !VALGRIND.
Instead, this demotes them to non-valgrind tests for SLOW_MACHINEs.

I started replacing all get_node() calls, but got bored, so then just did the
tests which call get_node() 3 times or more.
Ends up not making a measurable speed difference, but it does make some
things neater and more standard.
Times with SLOW_MACHINE=1 (given that's how Travis tests):
Time before (non-valgrind):
393 sec (had 3 failures?)
Time after (non-valgrind):
410 sec
Time before (valgrind):
890 seconds (had 2 failures)
Time after (valgrind):

I thought this was timing out because I made it slow with the
change to txprepare as a plugin. In fact, it was timing out
because sometimes gossip comes so fast it gets suppressed
and we never get the log messags.
Still, before this it took 98 seconds under valgrind and
24 under non-valgrind, so it's an improvement to time as
well as robustness.

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.
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.
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.
```
# 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>
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>
The adaptive MPP test was showing an issue with always using a routehint, even
when it wasn't necessary: we would insist on routhing to the entrypoint of the
routehint, even through the actual destination. If a channel on that loop
would result being over capacity we'd slam below 0, and then increase again by
unapplying the route. The solution really is not to insist on routing through
a routehint, so we implement random skipping of routehints, and we rotate them
if we have multiples.
Changelog-Fixed: plugin: `bcli` no longer logs a harmless warning about being unable to connect to the JSON-RPC interface.
Changelog-Added: plugin: Plugins can opt out of having an RPC connection automatically initialized on startup.
This PR includes the fix discussed on PR #3855. This fix was tested with the use case described inside the issue and worked.
Fixes: #3855

While we were unsetting the `payment->cmd` in case of a success to signal that
we should not return to the JSON-RPC command twice, we were not doing that in
the case of failures. This was causing multiple responses to a single incoming
command, and `lightningd` was correctly killing the plugin. This issue was
introduced through early returns (anything setting `payment->abort=true`) and
was caused in Rusty's case through an MPP timeout.

fundpsbt forces the caller to manually add their weight * feerate
to the satoshis they ask for. That means no named feerates.
Instead, create a startweight parameter and do the calc for them
internally, and return the feerate we used (and, while we're at it,
the estimated final weight).
This API change is best done now, as it would otherwise have to
be appended as a parameter.

This exercises something that is simply not possible without MPP, i.e., the
bundling of multiple paths to get sufficient capacity to perform the payment.
