SPARK-1621 Upgrade Chill to 0.3.6

It registers more Scala classes, including things like Ranges that we had to register manually before. See https://github.com/twitter/chill/releases for Chill's change log.

SPARK-1235: manage the DAGScheduler EventProcessActor with supervisor and refactor the DAGScheduler with Akka

https://spark-project.atlassian.net/browse/SPARK-1235

In the current implementation, the running job will hang if the DAGScheduler crashes for some reason (eventProcessActor throws exception in receive() )

The reason is that the actor will automatically restart when the exception is thrown during the running but is not captured properly (Akka behaviour), and the JobWaiters are still waiting there for the completion of the tasks

In this patch, I refactored the DAGScheduler with Akka and manage the eventProcessActor with supervisor, so that upon the failure of a eventProcessActor, the supervisor will terminate the EventProcessActor and close the SparkContext

thanks for @kayousterhout and @markhamstra to give the hints in JIRA

[SPARK-1608] [SQL] Fix Cast.nullable when cast from StringType to NumericType/TimestampType.

`Cast.nullable` should be `true` when cast from `StringType` to `NumericType` or `TimestampType`.
Because if `StringType` expression has an illegal number string or illegal timestamp string, the casted value becomes `null`.

SPARK-1467: Make StorageLevel.apply() factory methods Developer APIs

We may want to evolve these in the future to add things like SSDs, so let's mark them as experimental for now. Long-term the right solution might be some kind of builder. The stable API should be the existing StorageLevel constants.

SPARK-1648 Support closing JIRA's as part of merge script.

Adds an automated hook in the merge script that can close the JIRA,
set the fix versions, and leave a comment on the JIRA indicating the
PR in which it was resolved. This ensures that (a) we always close JIRA's
when issues are merged and (b) there is a link to the pull request in every JIRA.

This requires a python library called `jira-client`. We could look at embedding this
library in our project, but it seemed simple enough to just gracefully disable this
feature if it is not installed. It can be installed with `pip install jira-client`.

SPARK-1145: Memory mapping with many small blocks can cause JVM allocation failures

This includes some minor code clean-up as well. The main change is that small files are not memory mapped. There is a nicer way to write that code block using Scala's `Try` but to make it easy to back port and as simple as possible, I opted for the more explicit but less pretty format.
