This commit adds two new channel statuses which indicate the party that initatited closing the channel. These statuses are set in conjunction with the existing commit broadcast status so that we do not need to migrate existing logic to handle multiple types of closes. This status is set for locally initiated force closes in this commit because they follow a similar pattern to cooparative closes, marking the commitment broadcast then proceeding with tx broadcast. Remote force closes are added in the following commit, as they are handled differently.
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.
