This change avoids enforcing new reserved value when PSBT funding is not finished yet as new inputs and outputs may still be added that could change the outcome of the check. This originally failed in the scenario when funding a channel from external wallet *and depositing to on-chain wallet* was done simultaneously in a single transaction. If such transaction confirms then reserved UTXO is guaranteed to be available but the check didn't take it into account. The enforcement still occurs in the final step of PSBT funding flow, so it is safe. It also occurs in case of non-PSBT funding.
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.
