* Extract faulty channels selection from PaymentLifecycle
Move the logic of figuring out which channels/nodes should be ignored
when retrying after a payment failure out of the PaymentLifecycle.
We can figure this out looking only at the `PaymentFailure` generated,
and the multi-part logic could leverage these helpers.
* Refactor RouteResponse
It was useless to return `ignoreNodes` and `ignoreChannels`, it's rather
the responsibility of the caller (PaymentLifecycle) to store and update
these sets.
Preparing for the MPP move inside the router, we introduce a Route class
and let RouteResponse return a collection of Routes.
This creates some ugliness in PaymentLifecycle because of the `routePrefix`,
but this is just temporary: the `routePrefix` "hack" will be removed soon.
This is almost a drop-in replacement. I had to relaxed compiler
parameters to allow deprecated features though.
Main changes:
- relaxed compiler parameters to minimize impact (e.g. allow
deprecated features)
- `scala.collection.JavaConverters` -> `scala.jdk.CollectionConverters`
- `MultiMap` -> `MultiDict`
Compilation is 25% faster on my machine, compiler is a bit more strict
(it found an "invalid comparison" bug).
Do all the changes that will be required and are already possible to
minimize the diff:
- update dependencies
- `'something` -> `Symbol("something")`
- `BigDecimal.xValue()` -> `BigDecimal.xValue`
- `Map.filterKeys` -> `Map.filterKeys.toMap` (same for `Map.mapValues`)
- `def myMethod(...)` -> `def myMethod(...): Unit`
* removed the `Direction` class
* improved the non-reg test for htlcs
- check actual content instead of only success and roundtrip
- use randomized data for all fields instead of all-zero
- check the remaining data, not only the decoded value (codecs are
chained so a regression here will cause the next codec to fail)

* Rework plugin loading:
We now require the plugin to supply a manifest entry for the "Main-Class" attribute, this is used to load the plugin without doing illegal reflection operations. We also get rid of the dependency org.clapper.classutil
Let a sender manually split a payment and specify a trampoline route.
Fix two flaky tests where the order of payment parts could be
different, resulting in a failed equality test.
If we're relaying multiple HTLCs for the same payment_hash,
we need to list all of those.
The previous code only handled that when Trampoline was used.
With MPP and Trampoline (and particularly the combination of the two),
we need to keep track of multiple amounts, recipients and fees.
There's a trampoline fee and a fee to reach the first trampoline node.
The trampoline nodes must appear in the route, but not as payment recipients.
Adding new fields to payment events and DB structs lets us distinguish those.
We also relax the spec requirement about feature graph dependencies.
The requirement to include `var_onion_optin` in invoice feature bits
was added after the first Phoenix release.
Phoenix users will thus have non spec-compliant invoices in their
payment history.
We accept invoices that don't set this field; this is a harmless
spec violation (as long as we set it in new invoices).
