JavaSerializerInstance.serialize"

The solution is the save the RDD partitioner in a separate file in the RDD checkpoint directory. That is, `<checkpoint dir>/_partitioner`. In most cases, whether the RDD partitioner was recovered or not, does not affect the correctness, only reduces performance. So this solution makes a best-effort attempt to save and recover the partitioner. If either fails, the checkpointing is not affected. This makes this patch safe and backward compatible.

This bug was exposed as memory corruption in Timsort which uses copyMemory to copy
large regions that can overlap. The prior implementation did not handle this case
half the time and always copied forward, resulting in the data being corrupt.

Persist and Unpersist exist in both RDD and Dataframe APIs. I think they are still very critical in Dataset APIs. Not sure if my understanding is correct? If so, could you help me check if the implementation is acceptable?

compatible with encoder schema
When we build the `fromRowExpression` for an encoder, we set up a lot of "unresolved" stuff and lost the required data type, which may lead to runtime error if the real type doesn't match the encoder's schema.
For example, we build an encoder for `case class Data(a: Int, b: String)` and the real type is `[a: int, b: long]`, then we will hit runtime error and say that we can't construct class `Data` with int and long, because we lost the information that `b` should be a string.

The reason is that, for a single culumn `RowEncoder`(or a single field product encoder), when we use it as the encoder for grouping key, we should also combine the grouping attributes, although there is only one grouping attribute.

`JavaSerializerInstance.serialize` uses `ByteArrayOutputStream.toByteArray` to get the serialized data. `ByteArrayOutputStream.toByteArray` needs to copy the content in the internal array to a new array. However, since the array will be converted to `ByteBuffer` at once, we can avoid the memory copy.
This PR added `ByteBufferOutputStream` to access the protected `buf` and convert it to a `ByteBuffer` directly.

syn0Global and sync1Global in word2vec are quite large objects with size (vocab * vectorSize * 8), yet they are passed to worker using basic task serialization.
Use broadcast can greatly improve the performance. My benchmark shows that, for 1M vocabulary and default vectorSize 100, changing to broadcast can help,
1. decrease the worker memory consumption by 45%.
2. decrease running time by 40%.
This will also help extend the upper limit for Word2Vec.

This change seems large, but most of it is just replacing `byte[]`
with `ByteBuffer` and `new byte[]` with `ByteBuffer.allocate()`,
since it changes the network library's API.
The following are parts of the code that actually have meaningful
changes:
- The Message implementations were changed to inherit from a new
AbstractMessage that can optionally hold a reference to a body
(in the form of a ManagedBuffer); this is similar to how
ResponseWithBody worked before, except now it's not restricted
to just responses.
- The TransportFrameDecoder was pretty much rewritten to avoid
copies as much as possible; it doesn't rely on CompositeByteBuf
to accumulate incoming data anymore, since CompositeByteBuf
has issues when slices are retained. The code now is able to
create frames without having to resort to copying bytes except
for a few bytes (containing the frame length) in very rare cases.
- Some minor changes in the SASL layer to convert things back to
`byte[]` since the JDK SASL API operates on those.

This pull request fixes multiple issues with API doc generation.
- Modify the Jekyll plugin so that the entire doc build fails if API docs cannot be generated. This will make it easy to detect when the doc build breaks, since this will now trigger Jenkins failures.
- Change how we handle the `-target` compiler option flag in order to fix `javadoc` generation.
- Incorporate doc changes from thunterdb (in #10048).
Closes #10048.

zk://host:port for a multi-master Mesos cluster using ZooKeeper
* According to below doc and validation logic in [SparkSubmit.scala](https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala#L231), master URL for a mesos cluster should always start with `mesos://`
http://spark.apache.org/docs/latest/running-on-mesos.html
`The Master URLs for Mesos are in the form mesos://host:5050 for a single-master Mesos cluster, or mesos://zk://host:2181 for a multi-master Mesos cluster using ZooKeeper.`
* However, [SparkContext.scala](https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/SparkContext.scala#L2749) fails the validation and can receive master URL in the form `zk://host:port`
* For the master URLs in the form `zk:host:port`, the valid form should be `mesos://zk://host:port`
* This PR restrict the validation in `SparkContext.scala`, and now only mesos master URLs prefixed with `mesos://` can be accepted.
* This PR also updated corresponding unit test.

In https://github.com/apache/spark/pull/9409 we enabled multi-column counting. The approach taken in that PR introduces a bit of overhead by first creating a row only to check if all of the columns are non-null.

Change ```cumeDist -> cume_dist, denseRank -> dense_rank, percentRank -> percent_rank, rowNumber -> row_number``` at SparkR side.
There are two reasons that we should make this change:
* We should follow the [naming convention rule of R](http://www.inside-r.org/node/230645)
* Spark DataFrame has deprecated the old convention (such as ```cumeDist```) and will remove it in Spark 2.0.
It's better to fix this issue before 1.6 release, otherwise we will make breaking API change.
