updateMempoolForReorg()

void DisconnectedBlockTransactions::updateMempoolForReorg	(	Chainstate &	active_chainstate,
		bool	fAddToMempool,
		CTxMemPool &	pool
	)

Make mempool consistent after a reorg, by re-adding or recursively erasing disconnected block transactions from the mempool, and also removing any other transactions from the mempool that are no longer valid given the new tip/height.

Note: we assume that disconnectpool only contains transactions that are NOT confirmed in the current chain nor already in the mempool (otherwise, in-mempool descendants of such transactions would be removed).

Passing fAddToMempool=false will skip trying to add the transactions back, and instead just erase from the mempool as needed.
