We could end up with multiple channel hints, which is a bit wasteful. We now
look for existing ones before adding a new one, and if one exists we use the
more restrictive parameters.

We're lucky that we can distinguish the severity of the failure based on the
failcode, so we bubble up the one with the maximum failcode, and let callers
inspect details if they need more information.
We can have quite detailed information about our local channels, so call
`listpeers` before the `getroute` call on the root payment, to seed that
information in the channel_hints.
Since we end up consolidating some of the return values for `pay` and
`paystatus` and change the public interface we need to add the compatibility
flag and guard the switchover behind it.
most likely unused since the switch to libwally for internal blockchain
things.
these method names were clashing with ones that are to be introduced
with some libwally cleanups, so getting rid of them pre-emptively keeps
us libwally compatible
We need to keep them around so we can inspect them later. We'll also need a
background cleanup every once in a while to free some memory. More on that in
a future commit.
We were just handwaving the partid generation, which broke some tests that
expected the first payment attempt to always have partid=0, so here we just
track the partids assigned in the payment tree, starting at 0.
The status of what started as a simple JSON-RPC call is now spread across an
entire tree of partial payments and payment attempts. So we collect the status
in a single struct in order to report back success of failure.
This is just for testing for now, TLV payload computation will come next. We
stage all the payloads in deserialized form so modifiers can modify them more
easily and serialize them only before actually calling `createonion`.
This is necessary so we can build the absolute locktimes in the next step. For
now just fetch the blockheight on each (sub-)payment, later we can reuse the
root blockheight if it ends up using too much traffic.
A payment is considered finished if it is in a final state (success or
failure) or all its sub-payments are finished. If that's the case we notify
`payment_finished` and bubble up through `payment_child_finished`, eventually
bubbling up to the root, which can then report success of failure back to the
RPC command that initiated the whole process.
This is likely a bit of overkill for this type of functionality, but it is a
nice first use-case of how functionality can be compartmentalized into
modifiers. If makes swapping retry mechanisms in and out really simple.
This should make it easy for JSON-RPC functions and modifiers to get the
associated data for a given modifier name. Useful if a modifier needs to
access its parent's modifier data, or in other functions that need to access
modifier data, e.g., when passing destination pointers into the `param()`
call.
This commit can be reverted/skipped once we have implemented all the logic and
have feature parity with the normal `pay`. It's main purpose is to expose the
unfinished functionality to test it, without completely breaking the existing
`pay` command.

Changelog-None
The autocleaning will only happen if the autocleaninvoice-cycle startup
option is passed, which cannot happen if the plugin is started
post-startup.
Thus, it's less misleading for users to restrict its usage to startup.
Changelog-Added: plugins: The `autoclean` plugin is now static (you cannot manage it with the `plugin` RPC command anymore).

We did not take the value of --commit-fee into account : this removes
the unused option from lightningd and instead registers it in bcli,
where we set the actual feerate of commitment transactions. This also
corrects the documentation.
Changelog-Fixed: config: we now take the --commit-fee parameter into account.

Since we now over-write the wally malloc/free functions, we need to do
so for tests as well. Here we pull up all of the common setup/teardown
logic into a separate place, and update the tests that use libwally to
use the new common_setup core
