Tests whether we're able to route around a low-fee channel in the graph. We
should be able to find the more expensive route if the cheaper route is
depleted.
Changelog-Fixed: Plugins: pay now correctly estimates channel capacity
after payment failure, fixing some retry cases.
The `estimated_capacity` was properly substracted from the channel
hint, but adding the amount back did not work. The amount was added back
and then immediately substracted again. This caused the
`estimated_capacity` to ever decrease. This commit makes sure re-adding
the amount to the `estimated_capacity` works as expected.
is_local, ie. "is this side of the channel ours?" is not needed since we
can determine that predicate by evaluating
`scidd->dir == node_id_idx(self, peer)`
In the Min. Cost Flow solver we put a constraint on arcs capacities,
such that the total flow that can be allocated through a channel does
not exceed htlc_max. This solves two previous problem of the htlc_max
constraint at the MCF level.
Add spendable/receivable and is_local fields to the callback function
used in gossmods_from_listpeerchannels. This allows to do more fine
grained use of the listpeerchannels call.
The first use case is renepay, for which we need to ignore the htlc_max
of the local channels only.
Covered up by notleak() :(
Changelog-Fixed: lightingd: slow memory leak when using plugin hooks fixed (introduced in v23.11)

Changelog-Fixed: JSON-RPC: `fundchannel_start` now disallows a non-zero `mindepth` parameter if you ask for a zeroconf `channel_type`.
I was trying to debug test_zeroconf_open and getting very confused.
The reason: l0 is lightning-1, l1 is lightning-2, etc! And there are
two other tests where an l0 has been added at the front: fix them all
to avoid future confusion!

This allows for faster startup for Greenlight. We still require full sync
before *incoming* htlcs, and onchain operations.

We now *never* consider asking them anything, even if they are
capable (e.g. enabling full gossip stream). This aligns with
the latest spec proposal, where lack of `gossip_queries` means
"we don't have anything useful to say".

LDK doesn't set this feature if they don't have any useful gossip (mobile nodes)
and it was agreed at the spec meeting that we should repurpose this feature
to mean "I don't have any useful gossip".

Changelog-Removed: Plugins: no longer allow missing `id` field in commando requests (deprecated v23.02, EOL v24.02)
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
These were deprecated in v22.08 (invoice hook) and v0.8 (htlc_accepted hook), and
marked EOL in v23.02.
*PLEASE* complain if this breaks things for you: it's kind of a test canary of
the deprecation system!

Changelog-Removed: Plugins: `invoice_payment` and `htlc_accepted` hook `failure_code` response (derepcated v22.08 and v0.8, EOL v23.02)
Indeed, we now need to adjust our tests to use --i-promise-to-fix-broken-api-user
for the specific APIs past end-of-life.

We were duplicating the command name (e.g. "autocleaninvoice.autocleaninvoice"), and also not
handling listconfigs if they specified the (currently unused!) i-promise-to-fix-broken-api-user
option, which we are going to use next patch.

We tried to put *everything* into the "all" output, which didn't work
if there were other outputs!

Changelog-Fixed: JSON-RPC: `multifundchannel` with `all` as an amount works as expected.
This line is a cosmetic off-by-one error. There are 7 languages defined, but because counting starts at 0, the display is "Select [0-7]" when in fact only 0-6 are valid choices.
It's a u64, we should pass by copy. This is a big sweeping change,
but mainly mechanical (change one, compile, fix breakage, repeat).

This is the convention everywhere else: allocation ctx comes first, any
other context comes second.
