- coding style was not matching the rest of Jenkins
- IOUtils.closeQuietly is a lot more concise way of achieving the same
  thing.
- AtomicFileWriter.abort() does close, so no need to close it one more
  time.

Queue length has to count individual SubTask, so that heavy weight jobs
correctly provision required number of slaves through Cloud.

Bringing this to the parity with ParameterizedJobMixIn.doBuild()

Instead of returning JSON, it returns "201 Created" and responds with the location of the queue item, through which the caller can track how it passes through the queue and eventually gets built/cancelled.

The approach in pull request #750 that relies on
AbstractProject.getQueueItem() is inherently unreliable, because
item can be immediately built before the JSON is rendered, or it might
corresponds to other queued items if the build supports concurrent
builds, etc.

Massaging the pull request.

- Simplifying by reusing InterceptingExecutorService
- Not hiding the implementation class for better
  consistency with other ExecutorService impls in
  Jenkins.

Don't offer install without restart unless it's possible.

[JENKINS-20974] RunParameter with filtering enabled should not include builds which have not completed

The _activationButtonPressed get's set to false onMouseUp, so can not be used to decide if the menu is active or not.

This lets us support plugins written in Java8

[JENKINS-20857] - add unit test which recreates NullPointerException if selected build has been deleted

Pass through task-link CSS class to confirmationLink dialog

Add console-output class even while div is in progress

IE8 (and I assume other browsers that use a doctype pre-html5) interpret the span outside of the link, as in HTML4.01 you needed the closing tag.
http://www.w3.org/TR/REC-html40/struct/global.html#h-7.5.4

The code was causing a NPE in IE8 and users could not sort the columns.

>> cell.innerHTML = '<a href="#" class="sortheader">'+this.getInnerText(cell)+'<span class="sortarrow" /></a>';

>> cell.innerHTML ;
"<A class=sortheader href="#"> S<SPAN class=sortarrow></A></SPAN>"

>> cell.innerHTML = '<a href="#" class="sortheader">'+this.getInnerText(cell)+'<span class="sortarrow"></span></a>'

>> cell.innerHTML ;
"<A class=sortheader href="#"> S<SPAN class=sortarrow></SPAN></A>"

Upgrade remoting to 2.40

[FIXED JENKINS-22681] Fix of JENKINS-19418 should have used getById, not load, to avoid reloading the last build gratuitously.

[FIXED JENKINS-20597 JENKINS-21720] Improved config confirmation.
