In this commit, update the start up logic to gracefully handle a seemingly rare case. In this case, a peer detects local data loss with a set of active HTLCs. These HTLCs then eventually expire (they may or may not actually "exist"), causing a force close decision. Before this PR, this attempt would fail with a fatal error that can impede start up. To better handle such a scenario, we'll now catch the error when we fail to force close due to entering the DLP and instead terminate the state machine at the broadcast state. When a commitment transaction eventually confirms, we'll play it as normal. Fixes https://github.com/lightningnetwork/lnd/issues/7984
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.
