When expanding the slider to newer or older revisions the handler
for revision clicks should only be added to the new revisions.

We added this more as an experiment because we couldn't reliably
figure out what makes later .offset() calls fail. After looking into
the actual jQuery source code I realized the only way .offset() can
return undefined is when .length is zero. Which means the two checks
are redundant and one can be removed.
In case an element is not attached to the document an object with
{ top: 0, left: 0 } is returned.

Otherwise the `this` to call addColoredColumnBorders() inside of
that function is unkown when triggering the callback.
Can be verified working when collapsing the slider on master vs
this patch.

This is a first step in restructuring and consolidating the
highlight and tooltip creation. I use revision focus to communicate
the state when a revision is highlighted and shows a tooltip.
There's still stuff to untangle but I want to keep the diffs small.

It turns out the view class doesn't really do anything with the
RevisionList object. All it does it manually iterating the array of
revisions. But it doesn't call anything from the RevisionList class.
With a single exception.
Warning: This doesn't mean the RevisionList class is pointless. It's
critical because this is where the relativeSize fields are calculated.

Steps to reproduce:
* Make the browser window very narrow so that RevisionSlider can't
show the maximum number of gray bars.
* Go to a page with many revisions, open the RevisionSlider, and pin
it.
* Click the "Older edit" navigation link.
* Now make the browser window larger. Note how RevisionSlider will
have more space to show more gray bars.
* Use the browser's back button.
The pointer positions will jump to a random position.
The problematic code is in DiffPage.initOnPopState() where a "state"
object from the browser history is used to not only restore the
position of the blue and yellow pointers, but also the relative
starting position of the slider (the position you can manually change
with the large left/right arrow buttons). The way this relative
position is calculated depends on the number of revisions that fit
on a screen, which depends on the the available screen width. The
problem is that these numbers change after the state was recorded in
the browser history.
It might be that this patch still does not solve the issue in all
possible situations. But it already makes it behave much better.

The offsetNotAvailable method is part of the class ever since it was
created in Iadf7793. It always only checked one of the two columns.
This confuses me, to be honest. The PointerLine class is meant to have
exactly two instances: One for the left (yellow) and one for the
right (blue) lines. There should be no reason the left reaches into
the right, and vice versa.

I'm sure this does the same as before. Note that we don't care how
many elements are found. Only if at least one element is found.
Whichever is found first, we can stop searching then.
This is especially relevant when the first jQuery search doesn't
find anything. It scans the entire DOM tree (upwards) then.
Combining the two means the search can stop earlier.

The idea is to visually group things together that belong together.
This reduces duplication and hopefully makes the code easier to
read.

See T349208 for an explanation. It looks like the SliderView.render
function was written with the assumption that it's only triggered
once on construction time. But since T139101 it's triggered again
for every window resize event. This adds the same event handlers
over and over again to existing elements that aren't affected by
the SliderView.render function.
This will probably become even worse with I49878fd (T336729).
Please test this carefully. I'm not 100% sure this is the best
possible fix.

Calling .append() with a text message means jQuery will happily parse
it as HTML if it looks like HTML.

There's no need and probably just minimal gain to use these methods
with a revision as input. We could always just cleanup all tooltips
or wrapper highlighting before we set a new one. Makes the code
much simpler.

While working on renaming and consolidating some methods I found
it puzzeling, that the generic "highlight" word is already taken
by the filter mechanism. So I made these things more specific.
I checked the global wiki search if any user referes to these to
override CSS. It seems nobody does, so the change should be save.

According to the compatiblity standards to give Grade A support
for modern browser versions not older than 3 years, we do not need
these workarounds anymore.

Mousemove events seem to bubble up and can trigger unwanted hover
effects when the tooltip is appended to the pointer container.
This regression was introduced in the patch that supports tabbing
into the tooltips in I75ef7c32fb105526552eac387ff5a5bda8eefe1b

This is obsolete since I75ef7c3 where we had to replace the
`font-size: 0.8em` with a fixed 13px.

This was removed in I75ef7c3. Turns out it's needed for the
highlightable elements in the popups (e.g. when highlighting all
edits made by the same user). The text row in the popup gets a thin
gray border. This border needs some padding on the left.
The solution is to make the CSS selector more specific so it can
win over the problematic selector in Vector.

The pointer click and revision click handlers did almost the same
and the former was able to handle events from the latter. I merged
them and could then shortcut some code.
