This commit also adds two new maps to `PeerState` for keeping track
of `OutboundV1Channel`s and `InboundV1Channel`s so that further
commits are a bit easier to review.
To reduce interleaving in commits, we introduce a `context` variable
in methods to be moved in upcoming commits so there is minimal change
with the moves.
This is one of a series of commits to make sure methods are moved by
chunks so they are easily reviewable in diffs. Unfortunately they are
not purely move-only as fields to be updated for things to
compile, but these should be quite clear.
This commit also uses the `context` field where needed for compilation
and tests to pass due to the above change.

This is a first step for simplifying the channel state and introducing
new unfunded channel types that hold similar state before being promoted
to funded channels.
Essentially, we want the outer `Channel` type (and upcoming channel types)
to wrap the context so we can apply typestate patterns to the that wrapper
while also deduplicating code for common state and other internal fields.
Add a trait for finding routes for onion messages and parameterize
OnionMessenger with it. This allows OnionMessenger to reply to messages
that it handles via one of its handlers (e.g., OffersMessageHandler).
To avoid confusion in the upcoming MessageRouter trait, introduce an
OnionMessagePath struct that wraps the intermediate nodes and the
destination. Use this in OnionMessenger::send_onion_message.
Add a trait for handling BOLT 12 Offers messages to OnionMessenger and a
skeleton implementation of it for ChannelManager. This allows users to
either provide their own custom handling Offers messages or rely on a
version provided by LDK using stateless verification.
BOLT 12 Offers makes use of onion messages to request and respond with
invoices. Add these types and an error type to OnionMessageContents
along with the necessary parsing and encoding.
In an upcoming commit, messages for BOLT 12 offers are read from the
onion payload. Passing a logger allows for logging semantic errors when
parsing the messages.
If an InvoiceRequest or an Invoice delivered via an onion message cannot
be handled, the recipient should reply with an InvoiceError if a reply
path was given. Define the message and conversion from SemanticError.
Since we're breaking downgrade compatibility to LDK version 0.0.103
and before, we might as well go ahead and remove other code we have
for compatibility.
0.0.103 is now downright ancient, and certainly shouldn't exist in
production anywhere today. Thus, it seems fine to remove the
ability to create legacy stateful inbound payment entries.
Users downgrading to 0.0.103 will thus not be able to claim any
payments created on modern LDK, though we still retain the ability
to claim such payments at least for one more release.
The logic has been changed around duplicate keysend payments such that
it's no longer explicitly clear that we reject duplicate keysend
payments now that we handle receiving multi-part keysends. This test
catches that. Note that this also tests that we reject MPP keysends when
our config states we should, and that we reject MPP keysends without
payemnt secrets when our config states we support MPP keysends.
This commit refactors a significant portion of the receive validation in
`ChannelManager::process_pending_htlc_forwards` now that we repurpose
previous MPP validation logic to accomodate keysends. This also removes
a previous restriction on claiming, as well as tests sending and
receiving MPP keysends.
This commit adds the field `payment_data: FinalOnionHopData` to
`ReceiveKeysend` which will allow us to check for payment secrets and
total amounts which is needed to support receiving MPP keysends. This
field is non-backwards compatible since we wouldn't be able to handle
an MPP keysend properly if we were to downgrade to a prior version.
We also no longer reject keysends with payment secrets if we support MPP
keysend.
When routing a keysend payment, the user may want to signal to the
router whether to find multi-path routes in the
`PaymentParameters::for_keysend` helper, without going through manual
construction. Since some implementations do not support MPP keysend, we
have the user make the choice here rather than making it the default.
Some implementations will reject keysend payments with payment secrets,
so this commit also adds docs to `RecipientOnionFields` to communicate
this to the user.
The BOLT 12 test vectors had inadvertently left out a signature, but it
has since been added. Include a signature check in the corresponding
test for completeness.
The previous test vectors contained recurrences and older TLV types, and
therefore couldn't be parsed. Update the tests with the latest test
vectors from the spec and stop ignoring the tests.
