Matt Corallo f624cc9ac2 Inform ChannelManager when fulfilled HTLCs are finalized ... When an HTLC has been failed, we track it up until the point there exists no broadcastable commitment transaction which has the HTLC present, at which point Channel returns the HTLCSource back to the ChannelManager, which fails the HTLC backwards appropriately. When an HTLC is fulfilled, however, we fulfill on the backwards path immediately. This is great for claiming upstream HTLCs, but when we want to track pending payments, we need to ensure we can check with ChannelMonitor data to rebuild pending payments. In order to do so, we need an event similar to the HTLC failure event, but for fulfills instead. Specifically, if we force-close a channel, we remove its off-chain `Channel` object entirely, at which point, on reload, we may notice HTLC(s) which are not present in our pending payments map (as they may have received a payment preimage, but not fully committed to it). Thus, we'd conclude we still have a retryable payment, which is untrue. This commit does so, informing the ChannelManager via a new return element where appropriate of the HTLCSource corresponding to the failed HTLC.		2021-10-22 18:41:42 +00:00
