StreamingContext.start() can throw exception because DStream.validateAtStart() fails (say, checkpoint directory not set for StateDStream). But by then JobScheduler, JobGenerator, and ReceiverTracker has already started, along with their actors. But those cannot be shutdown because the only way to do that is call StreamingContext.stop() which cannot be called as the context has not been marked as ACTIVE.
The solution in this PR is to stop the internal scheduler if start throw exception, and mark the context as STOPPED.

This PR makes the types module in `pyspark/sql/types` work with pylint static analysis by removing the dynamic naming of the `pyspark/sql/_types` module to `pyspark/sql/types`.
Tests are now loaded using `$PYSPARK_DRIVER_PYTHON -m module` rather than `$PYSPARK_DRIVER_PYTHON module.py`. The old method adds the location of `module.py` to `sys.path`, so this change prevents accidental use of relative paths in Python.

This PR updates `genjavadocSettings` to use a patched version of `genjavadoc-plugin` that hides package private classes/methods/interfaces in the generated Java API doc. The patch can be found at: https://github.com/typesafehub/genjavadoc/compare/master...mengxr:spark-1.4.
It wasn't merged into the main repo because there exist corner cases where a package private Scala class has to be a Java public class in order to compile. This doesn't seem to apply to the Spark codebase. So we release a patched version under `org.spark-project` and use it in the Spark build. brkyvz is publishing the artifacts to Maven Central.
Need more people audit the generated APIs and make sure we don't have false negatives.
Current listed classes under `org.apache.spark.rdd`:
