There was a problem hiding this comment.
I wanted to expose this to the integration test, but not sure how to do it without introducing an extra cfg flag

With the merge of lightningdevkit/rust-lightning#4049, it is now possible for a static invoice server to forward the invoice request to the recipient if they are online.
This introduces an in-memory mailbox to hold onion messages until the receiver comes online. This is required for async payment `held_htlc_available` messages. The mailbox is bounded by a maximum number of peers and a maximum number of messages per peer.

Adds functionality for LSPs to hold onion messages for their clients until they come back online.
Depends on lightningdevkit/rust-lightning#4046
