Fork Settings

The following consensus fork settings are implemented in the libbitcoin-blockchain and exposed in both Bitcoin Node (BN) and Bitcoin Server (BS). Enabling a fork causes the node to validate blocks and transactions using the associated rule change once the fork has activated. BIP68, BIP112 and BIP113 support added in version 3.3. Retarget (regtest), BIP141, BIP143 and BIP147 support added in version 3.4.
