Anthony Towns 3c481f8921 signrawtransactionwithkey: better error messages for bad redeemScript/witnessScript
This adds checks to ensure the redeemScript/witnessScript actually
correspond to the provided scriptPubKey, and, if both are provided,
that they are sensibly related to each other.

Thanks to github user passionofvc for raising this issue.
