      WL#5223: Binary Log Group Commit
      
      Changing to freeze the caches before starting the write.
      
      Prior to the patch, the statement and transaction caches
      where frozen after the allocation had been made meaning
      that the data written was not taken into account when
      deciding if a rotation should occur.
      
      After the patch, the caches are frozen before allocation
      is done in the binary log and the number of bytes that
      needs to be written is taken into account when deciding
      if a rotation is necessary.
      
      As a result of changing the logic, some simplicification
      of cache management has also been made.
