[mempool] Remove ability to "opt-out" from replace-by-fee semantics. #37

Closed maaku closed 5 years ago

maaku commented 5 years ago

It is not truly possible to opt-out from replace-by-fee so long as there is a single miner willing to accept the conflicting transaction. We therefore drop support for the "opt-in" RBF semantics specified in BIP125, and instead consider ALL transactions as potentially subject to replacement.

Fixes #34.
