Updating ML Doc's *"Estimator, Transformer, and Param"* example to use `model.extractParamMap` instead of `model.fittingParamMap`, which no longer exists.

The minimal change would be to disable shading of Guava in the module,
and rely on the transitive dependency from other libraries instead. But
since Guava's use is so localized, I think it's better to just not use
it instead, so I replaced that code and removed all traces of Guava from
the module's build.

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 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.

Spark's `ExternalSorter` writes shuffle output files during sort-based shuffle. Sort-shuffle contains a configuration, `spark.shuffle.sort.bypassMergeThreshold`, which causes ExternalSorter to skip sorting and merging and simply write separate files per partition, which are then concatenated together to form the final map output file.
The code paths used during this bypass are almost completely separate from ExternalSorter's other code paths, so refactoring them into a separate file can significantly simplify the code.
In addition to re-arranging code, this patch deletes a bunch of dead code. The main entry point into ExternalSorter is `insertAll()` and in SPARK-4479 / #3422 this method was modified to completely bypass in-memory buffering of records when `bypassMergeSort` takes effect. As a result, some of the spilling and merging code paths will no longer be called when `bypassMergeSort` is used, so we should be able to safely remove that code.
There's an open JIRA ([SPARK-6026](https://issues.apache.org/jira/browse/SPARK-6026)) for removing the `bypassMergeThreshold` parameter and code paths; I have not done that here, but the changes in this patch will make removing that parameter significantly easier if we ever decide to do that.
This patch also makes several improvements to shuffle-related tests and adds more defensive checks to certain shuffle classes:
- DiskBlockObjectWriter now throws an exception if `fileSegment()` is called before `commitAndClose()` has been called.
- DiskBlockObjectWriter's close methods are now idempotent, so calling any of the close methods twice in a row will no longer result in incorrect shuffle write metrics changes. Calling `revertPartialWritesAndClose()` on a closed DiskBlockObjectWriter now has no effect (before, it might mess up the metrics).
- The end-to-end shuffle record count metrics tests have been moved from InputOutputMetricsSuite to ShuffleSuite. This means that these tests will now be run against all shuffle implementations rather than just the default shuffle configuration.
- The end-to-end metrics tests now include a test of a job which performs aggregation in the shuffle.
- Our tests now check that `shuffleBytesWritten == totalShuffleBytesRead`.
- FileSegment now throws IllegalArgumentException if it is constructed with a negative length or offset.
