[SPARK-14800][SQL] Dealing with null as a value in options for each
internal data source
## What changes were proposed in this pull request?
https://issues.apache.org/jira/browse/SPARK-14800
This PR add the support for `null` for values as options (as a default
value) for all the internal data source in Spark.
This PR introduces two classes
- `PrameterUtils`: This has some functions used in `CSVOptions` to check
`null` for other data sources.
- `OrcOptions`: Just like `ParquetOptions` this was separated (actually
they are almost identical).
## How was this patch tested?
Unit tests in `CSVSuite`, `JsonSuite`, `OrcHadoopFsRelationSuite,
`ParquetHadoopFsRelationSuite` and `LibSVMRelation`. Also,`sbt scalastyle`
