    [SPARK-7913][Core]Increase the maximum capacity of PartitionedPairBuffer and PartitionedSerializedPairBuffer

    The previous growing strategy is alway doubling the capacity. 
    This PR adjusts the growing strategy: doubling the capacity but if overflow, use the maximum
capacity as the new capacity. It increases the maximum capacity of PartitionedPairBuffer from
`2 ^ 29` to `2 ^ 30 - 1`, and the maximum capacity of PartitionedSerializedPairBuffer from
`2 ^ 28` to `(2 ^ 29) - 1`.
