PermittedEDADifficultyTransition()

bool PermittedEDADifficultyTransition	(	const Consensus::Params &	params,
		uint32_t	old_nbits,
		arith_uint256	new_target
	)

Return false if the proof-of-work requirement specified by new_target is not possible, given the proof-of-work on the prior block as specified by old_nbits.

This function only checks that the new value is within a factor of 4 of the old value for blocks.
