Discourage NOPs reserved for soft-fork upgrades
NOP1 through NOP10 are reserved for future soft-fork upgrades. When
such an upgrade occurs, the NOP argument will then require verification.
Rejecting transactions that contain these NOPs into the mempool will
discourage those transactions from being mined elsewhere and ensure
btcd will never mine such transactions. This prevents now
invalid scripts (according to the majority of hashing power) even if the
client has not yet upgraded.
Non-executed upgradable NOPs are still allowed as they will still be
valid post-upgrade.
