This PR brings arbitrary object support in UnsafeRow (both in grouping key and aggregation buffer).
Two object pools will be created to hold those non-primitive objects, and put the index of them into UnsafeRow. In order to compare the grouping key as bytes, the objects in key will be stored in a unique object pool, to make sure same objects will have same index (used as hashCode).
For StringType and BinaryType, we still put them as var-length in UnsafeRow when initializing for better performance. But for update, they will be an object inside object pools (there will be some garbages left in the buffer).
BTW: Will create a JIRA once issue.apache.org is available.

This patch excludes `hadoop-client`'s dependency on `mockito-all`. As of #7061, Spark depends on `mockito-core` instead of `mockito-all`, so the dependency from Hadoop was leading to test compilation failures for some of the Hadoop 2 SBT builds.

Allow HiveContext to connect to metastores of those versions; some new shims
had to be added to account for changing internal APIs.
A new test was added to exercise the "reset()" path which now also requires
a shim; and the test code was changed to use a directory under the build's
target to store ivy dependencies. Without that, at least I consistently run
into issues with Ivy messing up (or being confused) by my existing caches.

When there are massive tasks, such as `sc.parallelize(1 to 100000, 10000).count()`, the generated JS codes have a lot of string concatenations in the stage page, nearly 40 string concatenations for one task.
We can generate the whole string for a task instead of execution string concatenations in the browser.
Before this patch, the load time of the page is about 21 seconds.
After this patch, it reduces to about 17 seconds.
One disadvantage is that the generated JS codes become hard to read.

Spark's tests currently depend on `mockito-all`, which bundles Hamcrest and Objenesis classes. Instead, it should depend on `mockito-core`, which declares those libraries as Maven dependencies. This is necessary in order to fix a dependency conflict that leads to a NoSuchMethodError when using certain Hamcrest matchers.

This patch refactors the `python/run-tests` script:
- It's now written in Python instead of Bash.
- The descriptions of the tests to run are now stored in `dev/run-tests`'s modules. This allows the pull request builder to skip Python tests suites that were not affected by the pull request's changes. For example, we can now skip the PySpark Streaming test cases when only SQL files are changed.
- `python/run-tests` now supports command-line flags to make it easier to run individual test suites (this addresses SPARK-5482):
```
Usage: run-tests [options]
Options:
-h, --help show this help message and exit
--python-executables=PYTHON_EXECUTABLES
A comma-separated list of Python executables to test
against (default: python2.6,python3.4,pypy)
--modules=MODULES A comma-separated list of Python modules to test
(default: pyspark-core,pyspark-ml,pyspark-mllib
,pyspark-sql,pyspark-streaming)
```
- `dev/run-tests` has been split into multiple files: the module definitions and test utility functions are now stored inside of a `dev/sparktestsupport` Python module, allowing them to be re-used from the Python test runner script.

Test `infer_type` using a more fine-grained approach rather than comparing environments. Since `all.equal`'s behavior has changed in R 3.2, the test became unpassable.

This patch addresses a critical issue in the PySpark tests:
Several of our Python modules' `__main__` methods call `doctest.testmod()` in order to run doctests but forget to check and handle its return value. As a result, some PySpark test failures can go unnoticed because they will not fail the build.
Fortunately, there was only one test failure which was masked by this bug: a `pyspark.profiler` doctest was failing due to changes in RDD pipelining.

Some users have Hadoop installations on different paths across
their cluster. Currently, that makes it hard to set up some
configuration in Spark since that requires hardcoding paths to
jar files or native libraries, which wouldn't work on such a cluster.
This change introduces a couple of YARN-specific configurations
that instruct the backend to replace certain paths when launching
remote processes. That way, if the configuration says the Spark
jar is in "/spark/spark.jar", and also says that "/spark" should be
replaced with "{{SPARK_INSTALL_DIR}}", YARN will start containers
in the NMs with "{{SPARK_INSTALL_DIR}}/spark.jar" as the location
of the jar.
Coupled with YARN's environment whitelist (which allows certain
env variables to be exposed to containers), this allows users to
support such heterogeneous environments, as long as a single
replacement is enough. (Otherwise, this feature would need to be
extended to support multiple path replacements.)

This commit adds a new metric, `messageProcessingTime`, to the DAGScheduler metrics source. This metrics tracks the time taken to process messages in the scheduler's event processing loop, which is a helpful debugging aid for diagnosing performance issues in the scheduler (such as SPARK-4961).
In order to do this, I moved the creation of the DAGSchedulerSource metrics source into DAGScheduler itself, similar to how MasterSource is created and registered in Master.

Keep the same naming conventions for PythonMLLibAPI.
Only the following three functions is different from others
```scala
trainNaiveBayes
trainGaussianMixture
trainWord2Vec
```
So change them to
```scala
trainNaiveBayesModel
trainGaussianMixtureModel
trainWord2VecModel
```
It does not affect any users and public APIs, only to make better understand for developer and code hacker.
