Add rules--presently disabled--for using GetMedianTimePast as endpoint for lock-time calculations The lock-time code currently uses CBlock::nTime as the cutoff point for time based locked transactions. This has the unfortunate outcome of creating a perverse incentive for miners to lie about the time of a block in order to collect more fees by including transactions that by wall clock determination have not yet matured. By using CBlockIndex::GetMedianTimePast from the prior block instead, the self-interested miner no longer gains from generating blocks with fraudulent timestamps. Users can compensate for this change by simply adding an hour (3600 seconds) to their time-based lock times. If enforced, this would be a soft-fork change. This commit only adds the functionality on an unexecuted code path, without changing the behaviour of Bitcoin Core. 9 years ago			`/** Flags for LockTime() */`

Enable policy enforcing GetMedianTimePast as the end point of lock-time constraints Transactions are not allowed in the memory pool or selected for inclusion in a block until their lock times exceed chainActive.Tip()->GetMedianTimePast(). However blocks including transactions which are only mature under the old rules are still accepted; this is not the soft-fork required to actually rely on the new constraint in production. 9 years ago			`static const unsigned int STANDARD_LOCKTIME_VERIFY_FLAGS = LOCKTIME_MEDIAN_TIME_PAST;`
