Olaoluwa Osuntokun 1c92c79f15 sweep: add new AuxSweeper interface
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

Build Status MIT licensed GoDoc

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.
