[FIXED JENKINS-20327] When saving a list view, submit POST data with size proportional to the # of jobs selected for inclusion, not the number of options.
This can be done easily by setting json="true"; otherwise the default is to pass =false for each unselected job.
Ironically, even with this fix we are sending 2× what is needed,
since currently ListView.submit does not even check the json parameter for job names:
it only pays attention to top-level request parameters that the browser defines for selected checkboxes.
Ideally we could ask buildFormTree to ignore a given form element entirely, so as to avoid the wasted data.

The basic fix is to use ${rootURL} plus full model object URLs rather than relying on ${jobBaseUrl}.
This is made trickier by the fact that the model object URLs are computed inside ProgressiveRendering.compute,
and therefore will not be correct when nondefault views are in the crumb trail unless the original request information is present.
So modifying ProgressiveRendering to preserve a copy of the original request for use during computation.
(This could probably be used to simplify parts of AsynchPeople as well.)
Also improving AbstractItem.getUrl to properly construct a URL including views even when the current page is not inside the item;
it should suffice for some ancestor of the current item (or a view thereof) to be in the ancestor list of this page.

Documented this feature and integrated a newer version of Stapler.

I took the opportunity to reorder the content in the section, so that
the tree parameter becomes the main subject.

At this point, the depth parameter should be only used in a limited
circumstance, so it should be treated as such.

[FIXED JENKINS-22822] PeepholePermalink should maintain an in-memory cache of symlinks to avoid disk I/O.

[JENKINS-23151] Need to revert part of 5789f0c7 since codemirror-mode on f:textarea apparently does not work for lazy-load fragments.
