There is an inconsistency in the way we handle conflicting blocks atm - we add blocks to the block index as conflicting in
AcceptBlockHeaderbut we mark re-orged blocks as invalid inEnforceBestChainLock. Because of the latter, it works most of the time despite the fact that some logic for conflicting blocks is actually missing. This PR should fix it by always sticking to theBLOCK_CONFLICT_CHAINLOCKflag for conflicting blocks and implementing all the required logic around it.EDIT: the flag was introduced in #2923 btw
