This commit updates the key derivation to match the derivation required in order to construct and validate the commitment scheme that is used within the draft specification of the Lightning Network. The new scheme is very similar to the prior scheme aside from the following major differences: * Each key (not just the revocation key) now changes with each state. * A commitment point (a component of the revocation key) is used to randomize each key, and also generate new tweaked versions of the key. * Base points are used along with the commitment point to generate the keys for the commitment transaction. * Before the remote party would send over the fully valid revocation key. Now the remote party sends us a commitment point, which we then use our local revocation base point to generate their revocation key. |

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.
