success tx
This commit makes the HTLC resolutions having non-nil SignDetails
(meaning we can re-sign the second-level transactions) go through the
sweeper. They will be offered to the sweeper which will cluster them and
arrange them on its sweep transaction. When that is done we will further
sweep the output on this sweep transaction as any other second-level tx.
In this commit we do this for the HTLC success resolver and the
accompanying HTLC success transaction.
Extend the fee estimator to take into account parent transactions with
their weights and fees.
Do not try to cpfp parent transactions that have a higher fee rate than
the sweep tx fee rate.
This commit is a step to split the lnwallet package. It puts the Input
interface and implementations in a separate package along with all their
dependencies from lnwallet.
