Fixes #5287. The PSBT spec is a bit vague when it comes to the WitnessUtxo field of an input as it's not strictly required for witness inputs. Therefore Electrum for example does not include the field. We need to make the SegWit input check a bit more elaborate by looking at the output script of the UTXO and also the redeem script in case it's a nested SegWit spend.
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.
