new default driver

Changed all explicit references of the hierarchical driver to use a static
convinience method XStream2.getDefaultDriver() to ensure all XML operations
are using the same driver.

[JENKINS-48463] update hard coded references of XPP3Driver to KXml2Driver in order to support XMLv1.1

Making nullOut behavior opt-in, so limiting to AbstractItem and View (and in particular not Jenkins).

* [JENKINS-46759] Fixed bug related to views which filters build queue, jobs which has multiple sub steps were filtered incorrectly.

* Added test case for build queue filtering in views.

* [JENKINS-46759] Improved code based on feedback from PR; Fixed logic bug, moved logic to separate method and added limit to number of iteration when looking for owner task.

* Adding integration test for headers

* Removing proposal for refactoring to method objects

* Removing whitespace changeswq

* Fixing test

* Adding some interface default method implementations rather than catching AbstractMethodError or providing partial implementation classes.

* Show Javadoc warnings and errors, but not ‘Generating …/core/target/site/apidocs/jenkins/model/lazy/class-use/AbstractLazyLoadRunMap.html...’ and the like.

* Javadoc fixes.

* Review comments from @oleg-nenashev.

* Test fixes.

* Remove the unused import

* [JENKINS-42728] Updating view with CLI using different view type should fail

- Additionally, updating a view using an XML that will be converted by XStream via an alias
  will succeed.

[FIXES JENKINS-42728]

* Remove TestView

* update test

Also bumping to a distinct SNAPSHOT version for dependency builds.

Need to add tests, but first need to determine if this actually makes
sense as I've implemented it.

- Also while we are at it, modernise ViewDescriptor instantiation to allow for descriptor visibility filtering

- Such a pity that we don't auto-populate the CSS with the image sources for all the icons

* Update XStream drive to improve performance in xml serilization/deserialization

According XStream FAQ (http://x-stream.github.io/faq.html#Scalability):

XStream is a generalizing library, it inspects and handles your types on
the fly. Therefore it will normally be slower than a piece of optimized
Java code generated out of a schema. However, it is possible to increase
the performance anyway:

* Write custom converters for those of your types that occur very often in
your XML.
* Keep a configured XStream instance for multiple usage. Creation and
initialization is quite expensive compared to the overhead of XStream
when calling marshall or unmarshal.
* Use Xpp3 or StAX parsers.

So, I decided to move from old Xpp to new Xpp3.

* Change other occurance of XppDriver to Xpp3Driver as well

Also adds some API restrictions for JENKINS-33803.
