HOTFIX: Minor doc update for sbt change
name ec2 instances and security groups consistently

Security groups created by `spark-ec2` do not prepend “spark-“ to the
name.

Since naming the instances themselves is new to `spark-ec2`, it’s better
to change that pattern to match the existing naming pattern for the
security groups, rather than the other way around.

SPARK-2427: Fix Scala examples that use the wrong command line arguments index

The Scala examples HBaseTest and HdfsTest don't use the correct indexes for the command line arguments. This due to to the fix of JIRA 1565, where these examples were not correctly adapted to the new usage of the submit script.

[SPARK-2431][SQL] Refine StringComparison and related codes.

Refine `StringComparison` and related codes as follows:
- `StringComparison` could be similar to `StringRegexExpression` or `CaseConversionExpression`.
- Nullability of `StringRegexExpression` could depend on children's nullabilities.
- Add a case that the like condition includes no wildcard to `LikeSimplification`.

[SPARK-2415] [SQL] RowWriteSupport should handle empty ArrayType correctly.

`RowWriteSupport` doesn't write empty `ArrayType` value, so the read value becomes `null`.
It should write empty `ArrayType` value as it is.

[SPARK-2358][MLLIB] Add an option to include native BLAS/LAPACK loader in the build

It would be easy for users to include the netlib-java jniloader in the spark jar, which is LGPL-licensed. We can follow the same approach as ganglia support in Spark, which could be enabled by turning on "-Pganglia-lgpl" at build time. We can use "-Pnetlib-lgpl" flag for this.
