Allow <100 byte txs except those of 64 bytes

 Bitcoin ABC

This rule prevents a hash griding attack, where SPV wallets can confuse a 64 byte transaction for a merkle node. The amount of entropy in each 32-byte sections of the transaction is insufficient to prevent a preimage attack. In this case, a valid transaction could be found with a hash equal to the first, or last, 32 bytes of a 64-byte transaction.
