Detailed Description

BIP 9 allows multiple softforks to be deployed in parallel.

We cache per-period state for every one of them.

CheckUnknownActivations()

std::vector< std::pair< int, bool > > VersionBitsCache::CheckUnknownActivations	(	const CBlockIndex *	pindex,
		const CChainParams &	chainparams
	)
