◆ SignalsOptInRBF()

bool SignalsOptInRBF ( const CTransaction & tx)

Check whether the sequence numbers on this transaction are signaling opt-in to replace-by-fee, according to BIP 125.

Allow opt-out of transaction replacement by setting nSequence > MAX_BIP125_RBF_SEQUENCE (SEQUENCE_FINAL-2) on all inputs.

SEQUENCE_FINAL-1 is picked to still allow use of nLockTime by non-replaceable transactions. All inputs rather than just one is for the sake of multi-party protocols, where we don't want a single party to be able to disable replacement by opting out in their own input.
