[SPARK-9305] Rename org.apache.spark.Row to Item.

It's a thing used in test cases, but named Row. Pretty annoying because everytime I search for Row, it shows up before the Spark SQL Row, which is what a developer wants most of the time.

Author: Reynold Xin <rxin@databricks.com>

Closes #7638 from rxin/remove-row and squashes the following commits:
