This commit modifies the current core channel state machine in order to may a step towards BOLT-0002 and BOLT-0003 compliance. In this change, we abandon the prior revocation window, in favor of a fixed revocation window of size two. The revocation window will be filled at the start of the lifetime of the channel, and never extended from there until the channel has been fully closed. We now maintain two variables, the current un-revoked commitment point, and the next commitment point to use when creating a new state. The next commitment point must initially be inserted into the channel state with the InitNextRevocation method. A major difference between the prior revocation key handling is that the remote party now instead sends us the _commitment point_ in isolation, which we then use locally (with our revocation base point) to create the next full revocation key for _their_ commitment 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 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.
