Fixes #6626. If either of the two fields FinalScriptSig or FinalScriptWitness is set on an input of a PSBT then that results in most of the fields of that input not to be serialized in the packet anymore, since the input is considered to be complete. But because a signer isn't supposed to set any of the Final* fields, this was wrong from the beginning. Only the finalizer will set those fields.
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.
