* 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).
Implement https://github.com/lightningnetwork/lightning-rfc/pull/666
Keep the global/local split in Commitments to avoid backwards incompatibility in the codec.
Remove allowMultiPart API field: we instead rely on the MPP feature being set in nodeParams.
That means MPP-enabled nodes need to update their reference.conf.
Rework features:
* Add types to allow cleaner dependency validation.
* Most of the time we don't care whether a feature is activated as optional or mandatory, which caused duplicate code. This is now handled more cleanly.
* It also paves the way to annotate features with the places they should be advertised (Init vs NodeAnn vs ChannelAnn vs invoice).
Start relaying trampoline payments with multi-part aggregation (disabled by default,
must be enabled with config).
Recovery after a restart is correctly handled, even if payments were being forwarded.
No DB schema update in this commit.
The trampoline UX will be somewhat bad because many improvements/polish are missing.
Some shortcuts were taken, a few hacks here and there need to be fixed, but nothing too scary.
Those improvements will be done in separate commits before the next release.
This allows us to only use logback.xml to control the log level.
From akka docs [1]:
> If you set the loglevel to a higher level than DEBUG, any DEBUG events
will be filtered out already at the source and will never reach the
logging backend, regardless of how the backend is configured.
> You can enable DEBUG level for akka.loglevel and control the actual
level in the SLF4J backend without any significant overhead, also for
production.

This includes a bit of refactoring in `MultiPartPaymentLifecycle`. Note
that we can't use the `onTermination` handler to finish the spans,
because it is asynchronous and may not be called after a long time.
That's why we use a dedicated `myStop` function.
In Kamon 2.0, by default spans are automatically generated for tracked
actors, which we don't want because we define our own spans. That's why
there is an additional configuration in `application.conf`.
Add support for multi-part payments (MPP).
We can now send and receive multi-part payments, with a somewhat basic splitting algorithm that will be refined based on real-world usage.
Compatibility with other implementations hasn't been tested yet as they don't have a branch ready.
This compatibility testing may reveal small details that need to be changed and may invalidate pending multi-part invoices.
* Unify payment events (no more duplication between payment types and events)
* Factorize DB and eventStream interactions: this paves the way for sub-payments that shouldn't be stored in the DB nor emit events.
* Add more fields to the payments DB:
* bolt 11 invoice for sent payment
* external id (for app developers)
* parent id (AMP)
* target node id
* fees
* route (if success)
* failures (if failed)
* Re-work the PaymentsDb interface
* Clarify use of seconds / milliseconds in DB interfaces -> milliseconds everywhere
* Run SQL migrations inside transactions
For now:
- we only track some tasks (especially in the router, but not even
`node_announcement` and `channel_update`
- all db calls are monitored
- kamon is disabled by default
* Transport: add support for encryption key logging.
This is the format the wireshark lightning-dissector uses to be able to decrypt lightning messages.
* Logging: use a rolling file appender
Use one file per day, keep 90 days of logs with a total maximum size
capped at 5 Gb
* Router: log routing broadcast in debug level only
* removed max body size in http client
This is required because since f3676c6497
we retrieve multiple full blocks in parallel.
* trivial: removed unused code
* trivial: added log
* trivial: more unused code removal
This allows for a user of the library to implicitly pass the `ActorSystem` to the eclair node. Although if you are running multiple eclair instances on the same machine you need to make sure the `ActorSystems` that are passed implicitly are unique.
* improved logs on sig sent/received
* put 'sent announcements' log in debug
* added logging of IN/OUT wire messages
* added mdc support to IO classes
* reduced package length to 24 chars in logs
