In this commit, we add a new AuxSweeper interface. This'll take a set of inputs, and a change addr for the sweep transaction, then optionally return a new sweep output to be added to the sweep transaction. We also add a new NotifyBroadcast method. This'll be used to notify that we're _about_ to broadcast a sweeping transaction. The set of inputs is passed in, which allows the caller to prepare for the ultimate broadcast of the sweeping transaction. We also add ExtraTxOut to BumpRequest pass fees to NotifyBroadcast. This allows the callee to know the total fee of the sweeping transaction.
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.
