psbt: remove UTXO sanity check to allow fix for CVE 
As described in CVE-2020-14199 it is unsafe to only rely on witness
UTXO information when signing. Hardware wallets fixed this by also
requiring the full non-witness UTXO to be present for a witness input.
To be compatible with those newer hardware wallet firmware, we need to
remove the sanity checks that disallowed setting witness and non-witness
UTXOs at the same time.
See https://github.com/bitcoin/bitcoin/pull/19215 for comparison which
removed the sanity checks in Bitcoin Core.

Build Status Coverage Status ISC License GoDoc

Package btcutil provides bitcoin-specific convenience functions and types. A comprehensive suite of tests is provided to ensure proper functionality. See test_coverage.txt for the gocov coverage report. Alternatively, if you are running a POSIX OS, you can run the cov_report.sh script for a real-time report.

This package was developed for btcd, an alternative full-node implementation of bitcoin which is under active development by Conformal. Although it was primarily written for btcd, this package has intentionally been designed so it can be used as a standalone package for any projects needing the functionality provided.
