[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`.
