[SPARK-9022] [SQL] Generated projections for UnsafeRow
Added two projections: GenerateUnsafeProjection and FromUnsafeProjection, which could be used to convert UnsafeRow from/to GenericInternalRow.
They will re-use the buffer during projection, similar to MutableProjection (without all the interface MutableProjection has).
