This commit fixes signing of Taproot inputs when some of the other inputs of the transaction are not known to the wallet (such as a Pool account for example). If we want to sign for a Taproot (change) input when depositing into a Pool account the wallet won't know the Pool account input. So we need to make sure we pass it along inside the PrevOutputFetcher (which contains the UTXO information extracted from the PSBT).
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.
