spark.mllib and mllib in the documentation.
Replaces a number of occurences of `MLlib` in the documentation that were meant to refer to the `spark.mllib` package instead. It should clarify for new users the difference between `spark.mllib` (the package) and MLlib (the umbrella project for ML in spark).
It also removes some files that I forgot to delete with #10207

This PR tries to make execution hive's derby run in memory since it is a fake metastore and every time we create a HiveContext, we will switch to a new one. It is possible that it can reduce the flakyness of our tests that need to create HiveContext (e.g. HiveSparkSubmitSuite). I will test it more.

and change tracking function signature
SPARK-12244:
Based on feedback from early users and personal experience attempting to explain it, the name trackStateByKey had two problem.
"trackState" is a completely new term which really does not give any intuition on what the operation is
the resultant data stream of objects returned by the function is called in docs as the "emitted" data for the lack of a better.
"mapWithState" makes sense because the API is like a mapping function like (Key, Value) => T with State as an additional parameter. The resultant data stream is "mapped data". So both problems are solved.
SPARK-12245:
From initial experiences, not having the key in the function makes it hard to return mapped stuff, as the whole information of the records is not there. Basically the user is restricted to doing something like mapValue() instead of map(). So adding the key as a parameter.

This patch fixes a bug in the eviction of storage memory by execution.
## The bug:
In general, execution should be able to evict storage memory when the total storage memory usage is greater than `maxMemory * spark.memory.storageFraction`. Due to a bug, however, Spark might wind up evicting no storage memory in certain cases where the storage memory usage was between `maxMemory * spark.memory.storageFraction` and `maxMemory`. For example, here is a regression test which illustrates the bug:
```scala
val maxMemory = 1000L
val taskAttemptId = 0L
val (mm, ms) = makeThings(maxMemory)
// Since we used the default storage fraction (0.5), we should be able to allocate 500 bytes
// of storage memory which are immune to eviction by execution memory pressure.
// Acquire enough storage memory to exceed the storage region size
assert(mm.acquireStorageMemory(dummyBlock, 750L, evictedBlocks))
assertEvictBlocksToFreeSpaceNotCalled(ms)
assert(mm.executionMemoryUsed === 0L)
assert(mm.storageMemoryUsed === 750L)
// At this point, storage is using 250 more bytes of memory than it is guaranteed, so execution
// should be able to reclaim up to 250 bytes of storage memory.
// Therefore, execution should now be able to require up to 500 bytes of memory:
assert(mm.acquireExecutionMemory(500L, taskAttemptId, MemoryMode.ON_HEAP) === 500L) // <--- fails by only returning 250L
assert(mm.storageMemoryUsed === 500L)
assert(mm.executionMemoryUsed === 500L)
assertEvictBlocksToFreeSpaceCalled(ms, 250L)
```
The problem relates to the control flow / interaction between `StorageMemoryPool.shrinkPoolToReclaimSpace()` and `MemoryStore.ensureFreeSpace()`. While trying to allocate the 500 bytes of execution memory, the `UnifiedMemoryManager` discovers that it will need to reclaim 250 bytes of memory from storage, so it calls `StorageMemoryPool.shrinkPoolToReclaimSpace(250L)`. This method, in turn, calls `MemoryStore.ensureFreeSpace(250L)`. However, `ensureFreeSpace()` first checks whether the requested space is less than `maxStorageMemory - storageMemoryUsed`, which will be true if there is any free execution memory because it turns out that `MemoryStore.maxStorageMemory = (maxMemory - onHeapExecutionMemoryPool.memoryUsed)` when the `UnifiedMemoryManager` is used.
The control flow here is somewhat confusing (it grew to be messy / confusing over time / as a result of the merging / refactoring of several components). In the pre-Spark 1.6 code, `ensureFreeSpace` was called directly by the `MemoryStore` itself, whereas in 1.6 it's involved in a confusing control flow where `MemoryStore` calls `MemoryManager.acquireStorageMemory`, which then calls back into `MemoryStore.ensureFreeSpace`, which, in turn, calls `MemoryManager.freeStorageMemory`.
## The solution:
The solution implemented in this patch is to remove the confusing circular control flow between `MemoryManager` and `MemoryStore`, making the storage memory acquisition process much more linear / straightforward. The key changes:
- Remove a layer of inheritance which made the memory manager code harder to understand (53841174760a24a0df3eb1562af1f33dbe340eb9).
- Move some bounds checks earlier in the call chain (13ba7ada77f87ef1ec362aec35c89a924e6987cb).
- Refactor `ensureFreeSpace()` so that the part which evicts blocks can be called independently from the part which checks whether there is enough free space to avoid eviction (7c68ca09cb1b12f157400866983f753ac863380e).
- Realize that this lets us remove a layer of overloads from `ensureFreeSpace` (eec4f6c87423d5e482b710e098486b3bbc4daf06).
- Realize that `ensureFreeSpace()` can simply be replaced with an `evictBlocksToFreeSpace()` method which is called [after we've already figured out](https://github.com/apache/spark/blob/2dc842aea82c8895125d46a00aa43dfb0d121de9/core/src/main/scala/org/apache/spark/memory/StorageMemoryPool.scala#L88) how much memory needs to be reclaimed via eviction; (2dc842aea82c8895125d46a00aa43dfb0d121de9).
Along the way, I fixed some problems with the mocks in `MemoryManagerSuite`: the old mocks would [unconditionally](https://github.com/apache/spark/blob/80a824d36eec9d9a9f092ee1741453851218ec73/core/src/test/scala/org/apache/spark/memory/MemoryManagerSuite.scala#L84) report that a block had been evicted even if there was enough space in the storage pool such that eviction would be avoided.
I also fixed a problem where `StorageMemoryPool._memoryUsed` might become negative due to freed memory being double-counted when excution evicts storage. The problem was that `StorageMemoryPoolshrinkPoolToFreeSpace` would [decrement `_memoryUsed`](https://github.com/apache/spark/commit/7c68ca09cb1b12f157400866983f753ac863380e#diff-935c68a9803be144ed7bafdd2f756a0fL133) even though `StorageMemoryPool.freeMemory` had already decremented it as each evicted block was freed. See SPARK-12189 for details.

obtainTokenForHBase()
This lines up the HBase token logic with that done for Hive in SPARK-11265: reflection with only CFNE being swallowed.
There is a test, one which doesn't try to put HBase on the yarn/test class and really do the reflection (the way the hive introspection does). If people do want that then it could be added with careful POM work
+also: cut an incorrect comment from the Hive test case before copying it, and a couple of imports that may have been related to the hive test in the past.

visualizing SQL query plan
This PR adds a `private[sql]` method `metadata` to `SparkPlan`, which can be used to describe detail information about a physical plan during visualization. Specifically, this PR uses this method to provide details of `PhysicalRDD`s translated from a data source relation. For example, a `ParquetRelation` converted from Hive metastore table `default.psrc` is now shown as the following screenshot:

pushed down
Currently Parquet predicate tests all pass even if filters are not pushed down or this is disabled.
In this PR, For checking evaluating filters, Simply it makes the expression from `expression.Filter` and then try to create filters just like Spark does.
For checking the results, this manually accesses to the child rdd (of `expression.Filter`) and produces the results which should be filtered properly, and then compares it to expected values.
Now, if filters are not pushed down or this is disabled, this throws exceptions.

Buffer underflow exception
Jira: https://issues.apache.org/jira/browse/SPARK-12222
Deserialize RoaringBitmap using Kryo serializer throw Buffer underflow exception:
```
com.esotericsoftware.kryo.KryoException: Buffer underflow.
at com.esotericsoftware.kryo.io.Input.require(Input.java:156)
at com.esotericsoftware.kryo.io.Input.skip(Input.java:131)
at com.esotericsoftware.kryo.io.Input.skip(Input.java:264)
```
This is caused by a bug of kryo's `Input.skip(long count)`(https://github.com/EsotericSoftware/kryo/issues/119) and we call this method in `KryoInputDataInputBridge`.
Instead of upgrade kryo's version, this pr bypass the kryo's `Input.skip(long count)` by directly call another `skip` method in kryo's Input.java(https://github.com/EsotericSoftware/kryo/blob/kryo-2.21/src/com/esotericsoftware/kryo/io/Input.java#L124), i.e. write the bug-fixed version of `Input.skip(long count)` in KryoInputDataInputBridge's `skipBytes` method.

The checker tries to follow as closely as possible the guidelines of
the code style document, and makes some decisions where the guide is
not clear. In particular:
- wildcard imports come first when there are other imports in the
same package
- multi-import blocks come before single imports
- lower-case names inside multi-import blocks come before others
In some projects, such as graphx, there seems to be a convention to
separate o.a.s imports from the project's own; to simplify the
checker, I chose not to allow that, which is a strict interpretation
of the code style guide, even though I think it makes sense.
Since the checks are based on syntax only, some edge cases may
generate spurious warnings; for example, when class names start
with a lower case letter (and are thus treated as a package name
by the checker).
The checker is currently only generating warnings, and since there
are many of those, the build output does get a little noisy. The
idea is to fix the code (and the checker, as needed) little by little
instead of having a huge change that touches everywhere.

Check Java compatibility for MLlib for this release.
fix:
1. `StreamingTest.registerStream` needs java friendly interface.
2. `GradientBoostedTreesModel.computeInitialPredictionAndError` and `GradientBoostedTreesModel.updatePredictionError` has java compatibility issue. Mark them as `developerAPI`.
TBD:
[updated] no fix for now per discussion.
`org.apache.spark.mllib.classification.LogisticRegressionModel`
`public scala.Option<java.lang.Object> getThreshold();` has wrong return type for Java invocation.
`SVMModel` has the similar issue.
Yet adding a `scala.Option<java.util.Double> getThreshold()` would result in an overloading error due to the same function signature. And adding a new function with different name seems to be not necessary.
