  2. mempool: make txn's below 65 non-witness bytes non-standard 

    This is to mitigate CVE-2017-12842. Along the way, also error when
deserializing transactions that have the witness marker flag set
but have no witnesses. This matches Bitcoin Core's behaviour initially
introduced here bitcoin/bitcoin#14039. Allowing
such transactions is benign, but this makes sure that our parsing code
matches Core's exactly.
