In this commit, we add a new `LastUnusedAddress` method to the `WalletController` interface. Callers can use this new method to graph the last unused address, which can be useful for UIs that want to refresh the address, but not cause nearly unbounded address generation. The implementation for `btcwallet` uses the existing `CurrentAddress` method. We've also added a new integration tests to exercise the new functionality.
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.
