0fb2e69815CreateTransaction: Assume minimum p2sh-p2wpkh spend size for unknown change (Gregory Sanders)b06483c96aRemove stale comment in CalculateMaximumSignedInputSize (Gregory Sanders) Pull request description: This is triggered anytime a fundraw type call(psbt or legacy) is used with a change output address that the wallet doesn't know how to sign for. This regression was added in6a34ff5335since BnB coin selection actually cares about this. The fix is to assume the smallest typical spend, a P2SH-P2WPKH, which is calculated using a "prototype" dummy signature flow. Future work could generalize this infrastructure to get estimated sizes of inputs for a variety of types. I also removed a comment which I believe is stale and misleading.
