      Performs a checkpoint operation on a redo thread, this is when a redo log rolls to an archive.
      Parameters:
      currentState - the current state to be mutated, should not be null
      threadId - the thread id
      checkpointScn - the scn to store in the checkpoint
      Returns:

      Parameters:
      currentState - the current state to be mutated, should not be null
      threadId - the thread id
      changes - the number of changes to advance by before going offline, can be 0.
      Returns:

      threadId - the thread id
      changes - the number of changes to advance by
      increaseSequence - whether to increase the sequence number
      Returns:
      a new redo thread state with the thread modifications
