[SQL] Update SparkSQL and ScalaTest in branch-1.0 to match master.

#511 and #863 got left out of branch-1.0 since we were really close to the release.  Now that they have been tested a little I see no reason to leave them out.

Author: Michael Armbrust <michael@databricks.com>
Author: witgo <witgo@qq.com>

Closes #1078 from marmbrus/branch-1.0 and squashes the following commits:

22be674 [witgo]  [SPARK-1841]: update scalatest to version 2.1.5
fc8fc79 [Michael Armbrust] Include #1071 as well.
c5d0adf [Michael Armbrust] Update SparkSQL in branch-1.0 to match master.
