Rusty Russell 6195d953cc plugins: use "slow" feerate for mutual close negotiation.
We're rarely in a hurry here, and bitcoind is aggressive with fees.
You can always spend this output if you really have to, using CPFP.

Changelog-Changed: Protocol: mutual closing feerate reduced to "slow" to avoid overpaying.

Christian Decker 5a87e88ee5 pytest: Add test for failcode conversion
We added a conversion of failcodes that do not have sufficient information in
faac4b28ad. That means that a failcode that'd require additional information
in order to be a correct error to return in an onion is mapped to a generic
one since we can't backfill the information.

This tests that the mapping is performed correctly and replicates the
situation in #4070

Christian Decker bd811fbd1a pyln: Add safe fallback results for hooks
Hooks do not tolerate failures at all. If we return a JSON-RPC error to a hook
call the only thing the main daemon can really do is to crash. This commit
adds a mapping of error to a safe fallback result, including a warning to the
node operator that this should be addressed in the plugin. The warning is
reported as a `**BROKEN**` message, and should therefore fail any testing done
on the plugin.

Changelog-Fixed: pyln: Fixed HTLCs hanging indefinitely if the hook function raises an exception. A safe fallback result is now returned instead.

Changelog-Deprecated: plugin: `bcli` replacements should note that `sendrawtransaction` now has a second required Boolean argument, `allowhighfees`, which if `true`, means ignore any fee limits and just broadcast the transaction.

Rusty Russell 2696ec6ccb pytest: fix assumptions in test_withdraw_misc
First, simplify: amount is set to 1000000, but then we deposit 1000000 + 0.01btc
(i.e. 2000000), and we always use 2 * amount.  Just use a single constant to
make it clear.

Secondly, we assume that the wallet considers outputs spent as soon as
we created the tx: this will not be true once withdraw uses sendpsbt.
So, we generate blocks, but now sometimes withdraw will pick up change
txs, so we need to reserve them to avoid that messing our coinmovements.

Finally, we assumed the withdrawl order was BIP69, which becomes
variable.

Rusty Russell 74e960c20b pytest: increase channel sizes so they reach min capacity with option_anchor_outputs
With a feerate of 7500perkw and subtracting 660 sats for anchors, a
20,000 sat channel has capacity about 9800 sat, below our default:

	You gave bad parameters: channel capacity with funding 20000sat, reserves 546sat/546sat, max_htlc_value_in_flight_msat is 18446744073709551615msat, channel capacity is 9818sat, which is below 10000000msat

So bump channel amounts.

Rusty Russell 8cf2fff91b pytest: generalize tests.
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!).

Rusty Russell fde353ab00 pytest: use get_nodes more widely.
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

Christian Decker 2146a548bd plugin: Do not return multiple times from `pay`
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.

you only see this if the test fails, but it's really helpful.
