Description

This is a follow-up of HIVE-16534.

In ValidReadTxnList.writeToString, we write out open and aborted transactions as two sorted lists. We can take advantage of that and merge sort them together when reading them back in readFromString. Note that the aborted bits should also be marked properly during the merge sort.
