This commit changes the `NewBreachRetribution` to use the new revocation log format, while maintaining the compatibilty to use an older revocation log format. Unit tests have been added to make sure a breach retribution can be created in both log formats. This also means the watch tower needs to pass the relevant commit tx at its backup height when creating the breach retribution during backing up. This is achieved by recording the current remote commitment state before advancing the remote commitment chain.
lnwallet
The lnwallet package implements an abstracted wallet controller that is able to drive channel funding workflows, a number of script utilities, witness generation functions for the various Lightning scripts, revocation key derivation, and the commitment update state machine.
The package is used within lnd as the core wallet of the daemon. The wallet
itself is composed of several distinct interfaces that decouple the
implementation of things like signing and blockchain access. This separation
allows new WalletController implementations to be easily dropped into
lnd without disrupting the code base. A series of integration tests at the
interface level are also in place to ensure conformance of the implementation
with the interface.
