[SPARK-9753] [SQL] TungstenAggregate should also accept InternalRow instead
of just UnsafeRow
https://issues.apache.org/jira/browse/SPARK-9753
This PR makes TungstenAggregate to accept `InternalRow` instead of just
`UnsafeRow`. Also, it adds an `getAggregationBufferFromUnsafeRow` method to
`UnsafeFixedWidthAggregationMap`. It is useful when we already have grouping
keys stored in `UnsafeRow`s. Finally, it wraps `InputStream` and `OutputStream`
in `UnsafeRowSerializer` with `BufferedInputStream` and `BufferedOutputStream`,
respectively.
