* Replace blue score with DAA score in UTXO entries * Use DAA score for coinbase maturity * Use DAA score for sequence lock * Fix calcBlockSubsidy to use DAA score * Don't pay to blocks that are not included in the DAA added blocks, and bestow red blocks reward to the merging block * Fix TestGetPruningPointUTXOs * Fix TestTransactionAcceptance * Fix TestChainedTransactions * Fix TestVirtualDiff * Fix TestBlockWindow * Fix TestPruning * Use NewFromSlice instead of manually creating the hash set * Add assert * Add comment * Remove redundant call to UpdateDAADataAndReturnDifficultyBits * Add RequiredDifficulty, rename UpdateDAADataAndReturnDifficultyBits to StageDAADataAndReturnRequiredDifficulty and add comments * Make buildUTXOInvalidHeader get bits as an argument * Fix comments
