In this commit, we update the channel state machine with a new set of functional options that can be used to create/set the musig session state. When a channel is made during the funding process, the set of nonces we want to use is already known, so we allow them to be passed in. Similarly, once the channel is confirmed, then we'll need to create another channel instance that this times carries the newly generated nonces to send along side funding_locked. We also add some utility methods to permit callers to properly generate nonces in the various contexts.
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.
