[HOT FIX] [BUILD] Fix maven build failures
This patch fixes a build break in maven caused by #6441.
Note that this patch reverts the changes in flume-sink because
this module does not currently depend on Spark core, but the
tests require it. There is not an easy way to make this work
because mvn test dependencies are not transitive (MNG-1378).
For now, we will leave the one test suite in flume-sink out
until we figure out a better solution. This patch is mainly
intended to unbreak the maven build.

[SPARK-7855] Move bypassMergeSort-handling from ExternalSorter to own
component
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.

[SPARK-5610] [DOC] update genjavadocSettings to use the patched version of
genjavadoc
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.
