This is split from I4431882 to make that easier to review. This just
moves existing code around. It should not make any difference.

This is split from I4431882 to make that much easier to review.
Additional changes:
* Remove plural "s" from setRevisionPreviewHighlight
* Add "All" to removeAllRevisionPreviewHighlights
* Merge two methods into a single enableRevisionPreviewHighlights

The extra "div.…" doesn't make the selectors more specific or
anything. The class name alone is unique. This makes the code
simpler, less brittle, and potentially even faster.

This code is updating the position and length of the yellow/blue
horizontal lines in the middle of the slider, left/right to the
yellow/blue circles.
1. setSliderLineCSS is called two times. A lot of the code before
is identical. Move all code that is identical into setSliderLineCSS.
2. The two single-use methods are very short now. Nothing but a
single function call. Merge the two calls into a single method.
Notice that `-0.5 * this.revisionWidth` is the same as
`-this.revisionWidth / 2`. I was able to make one disappear by
slowly transforming the code. It still does the same as before.

Storing a new entry in the browser history is the normal, default
thing to do. The only exception is on initialization, when the slider
is initialized from the browser history.
I hope this makes the code a little easier to read.

This click handler is assigned to many different elements. Not all
of them can be used as a source for a data-pos="…" attribute. But a
lot can.
Again, this patch alone will not actually fix T352169. But it will
improve the situation a lot, according to my local tests. Many of
the clicks will start to work fine on RTL wikis because the
problematic pixel-based getRevisionPositionFromLeftOffset
calculations are not used any more.
Steps to reproduce: Go to a RTL page with a very long history, e.g.
https://he.wikipedia.org/wiki/Special:Diff/38031767?uselang=he
Click on one of the gray bars in the right half of the slider. This
will not work, i.e. the slider will not move to this position but
to a totally different one. This is the bug described in T352169.
I noticed that a browser zoom other than 100% can cause many more
problems that are unrelated to this patch. Please test with 100%.

The method is only called from two places, and both do very similar
things before the call. This duplication can be merged.
One notable difference is that .scrollLeft() was possibly called
twice before. The first call was pointless anyway. The argument for
.scrollLeft() is absolute, not relative.
This code cleanup is motivated by T352169, but doesn't solve it.

This was almost the exact same code, with very few differences (e.g.
different CSS classes, and different icons).
Another change in the same file is the removal of an extra
`!== undefined` check. This is impossible. I can't tell why this was
there. Maybe an artifact from when this was developed?

Turns out we can run into this failure situation even if everything
goes according to plan. It is possible to click just one pixel outside
of the valid range, e.g. on the very right corner right next to the
last bar. This is supposed to not do anything anyway, and correctly
doesn't do anything from the user's perspective. But it shows up as a
failure in the JavaScript console.

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

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.

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.

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.

Adds two handlers to make sure the popup is closed when the focus
moves away from either the pointers or contents of the a popup.

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.

I'm not sure why it was done this way. Probably because it doesn't
make an actual difference from the user's perspective. My motivation
is: When we already called the code that auto-expands the
RevisionSlider UI then it doesn't make much sense to give the user
a keyypress handler that does the same a second time.
Possibly even related to T342556?
This patch also contains a few small, unrelated code cleanups.

It took me a while to come up with a solution for this, but there
are several things that seem to trigger the showTooltip method a
bit to often.
Tooltips can be triggered either by the handlers that deal with
mouseenter and mouseleave events that also trigger revision high-
lighling. But tooltips can also be triggered when you use the
keyboard or the mouse while dragging sliders.
The mechanics on what's highlighted and what's triggering a popup
are a bit weiridly setup and there could probably be a major re-
factoring done to make things clear ( for example the show popup
method also highlights the revision but the highlight revision
mehtod does not ). I had a quick approach to fix that, but it's
not too easy.
Another issue is, that some events fire off a delayed popup close
mechanism. So the solution here reads like:
If you are triggered to show a popup, and that popup exists
already, stop the delayed popup close mechanism and bail out.

This code was designed for the left/right cursor keys. But it
currently triggers on all keys. This causes confusing behavior when
tabbing through the UI. This code also triggers on tab/shift+tab,
which can be visibly seen when the wrong popup opens. It also
triggers on enter, which feels like it's intentional, but is nore a
happy accident.
Especially note how the buildTabbingRulesOnKeyUp handler directly
below does the exact same: It only acts on left/right, but no other
key.
We intentionally keep the existing (even if bogus) behavior for the
enter key. To be replaced with something better in a later patch.

According to https://api.jquery.com/html/ a jQuery object is not
supported in .html() although is works.
The .empty() is needed to avoid multiple sliders on resize.

Mostly motivated by the missing @type tag.
Also make the syntax more compact. This is significantly easier to
read, I would like to argue.
