[SPARK-10873] Support column sort and search for History Server using jQuery DataTable and REST API. Before this commit, the history server was generated hard-coded html and can not support search, also, the sorting was disabled if there is any application that has more than one attempt. Supporting search and sort (over all applications rather than the 20 entries in the current page) in any case will greatly improve user experience. 1. Create the historypage-template.html for displaying application information in datables. 2. historypage.js uses jQuery to access the data from /api/v1/applications REST API, and use DataTable to display each application's information. For application that has more than one attempt, the RowsGroup is used to merge such entries while at the same time supporting sort and search. 3. "duration" and "lastUpdated" rest API are added to application's "attempts". 4. External javascirpt and css files for datatables, RowsGroup and jquery plugins are added with licenses clarified. Snapshots for how it looks like now: History page view:  Search:  Sort by started time:  Author: zhuol <zhuol@yahoo-inc.com> Closes apache#10648 from zhuoliu/10873.
The right margin of the history page is little bit off. A simple fix for that issue. Author: zhuol <zhuol@yahoo-inc.com> Closes apache#11029 from zhuoliu/13126.
…Query DataTables Made sure the old tables continue to use the old css and the new DataTables use the new css. Also fixed it so the Safari Web Inspector doesn't throw errors when on the new DataTables pages. Author: Alex Bozarth <ajbozart@us.ibm.com> Closes apache#11038 from ajbozarth/spark13124.
……ry server to ensure a single large log does not block other logs from being rendered. The patch makes event log processing multi threaded. Existing tests pass, there is no new tests needed to test the functionality as this is a perf improvement. I tested the patch locally by generating one big event log (big1), one small event log(small1) and again a big event log(big2). Without this patch UI does not render any app for almost 30 seconds and then big2 and small1 appears. another 30 second delay and finally big1 also shows up in UI. With this change small1 shows up immediately and big1 and big2 comes up in 30 seconds. Locally it also displays them in the correct order in the UI. Author: Parth Brahmbhatt <pbrahmbhatt@netflix.com> Closes apache#11800 from Parth-Brahmbhatt/SPARK-13988.

…boxing/unboxing ## What changes were proposed in this pull request? This PR improve performance of Dataset.map() for primitive types by removing boxing/unbox operations. This is based on [the discussion](apache#16391 (comment)) with cloud-fan. Current Catalyst generates a method call to a `apply()` method of an anonymous function written in Scala. The types of an argument and return value are `java.lang.Object`. As a result, each method call for a primitive value involves a pair of unboxing and boxing for calling this `apply()` method and a pair of boxing and unboxing for returning from this `apply()` method. This PR directly calls a specialized version of a `apply()` method without boxing and unboxing. For example, if types of an arguments ant return value is `int`, this PR generates a method call to `apply$mcII$sp`. This PR supports any combination of `Int`, `Long`, `Float`, and `Double`. The following is a benchmark result using [this program](https://github.com/apache/spark/pull/16391/files) with 4.7x. Here is a Dataset part of this program.

## What changes were proposed in this pull request?
After we move the ExtractPythonUDF rule into physical plan, Python UDF can't work on top of aggregate anymore, because they can't be evaluated before aggregate, should be evaluated after aggregate. This PR add another rule to extract these kind of Python UDF from logical aggregate, create a Project on top of Aggregate.
## How was this patch tested?
Added regression tests. The plan of added test query looks like this:
```
== Parsed Logical Plan ==
'Project [<lambda>('k, 's) AS t#26]
+- Aggregate [<lambda>(key#5L)], [<lambda>(key#5L) AS k#17, sum(cast(<lambda>(value#6) as bigint)) AS s#22L]
+- LogicalRDD [key#5L, value#6]
== Analyzed Logical Plan ==
t: int
Project [<lambda>(k#17, s#22L) AS t#26]
+- Aggregate [<lambda>(key#5L)], [<lambda>(key#5L) AS k#17, sum(cast(<lambda>(value#6) as bigint)) AS s#22L]
+- LogicalRDD [key#5L, value#6]
== Optimized Logical Plan ==
Project [<lambda>(agg#29, agg#30L) AS t#26]
+- Aggregate [<lambda>(key#5L)], [<lambda>(key#5L) AS agg#29, sum(cast(<lambda>(value#6) as bigint)) AS agg#30L]
+- LogicalRDD [key#5L, value#6]
== Physical Plan ==
