Firefox 96-100 used to report the column number smaller by 2 than it should
in the `parsererror` element generated for invalid XML documents. Since that
version range is unsupported now and it includes no ESR versions, the workaround
can now be dropped.

The spec requires that CSS variable values are trimmed. In browsers that do
this - mainly, Safari, but also Firefox if the value only has leading
whitespace - we currently return undefined; in other browsers, we return
an empty string as the logic to fall back to undefined happens before
trimming.
This commit adds another explicit callback to `undefined` to have it consistent
across browsers.
Also, more explicit comments about behaviors we need to work around in various
browsers have been added.

This change makes jQuery skip falsy values in `addClass( array )`
& `removeClass( array )` instead of stopping iteration when the first falsy
value is detected. This makes code like:
```js
elem.addClass( [ "a", "", "b" ] );
```
add both the `a` & `b` classes.
The code was also optimized for size a bit so it doesn't increase the
minified gzipped size.

This is a version of gh-4993 for the `3.x-stable` branch.
The GitHub UI treats `#NUMBER` as referring to its own issues which is confusing
when in jQuery source it's usually referring to the old deprecated Trac instance
at https://bugs.jquery.com. This change replaces all such Trac references with
`trac-NUMBER`.
A few of the references came with the Sizzle integration and referred to the
Sizzle GitHub bug tracker. Those have been replaced with full links instead.
A new entry describing issue reference conventions has been added to README.

In HTTP/2, status message is not supported and whatever is reported as

When evaluating scripts, jQuery strips out the possible wrapping HTML comment
and a CDATA section. However, all supported browsers are already doing that
when loading JS via appending a script tag to the DOM which is how we've been
doing `jQuery.globalEval` since jQuery 3.0.0. jQuery logic was imperfect, e.g.
it just stripped the `<!--` and `-->` markers, respectively at the beginning or
the end of the script contents. However, browsers are also stripping everything
following those markers in the same line, treating them as single-line comments
delimiters; this is now also mandated by ECMAScript 2015 in Annex B. Instead
of fixing the jQuery logic, just let the browser do its thing.
We still need to strip CDATA sections for backwards compatibility. This
shouldn't be needed as in XML documents they're already not visible when
inspecting element contents and in HTML documents they have no meaning but
we're preserving that logic for backwards compatibility. This will be removed
completely in 4.0.

The `_default` function in the special event settings for focus/blur has
always returned `true` since gh-4813 as the event was already being fired
from `leverageNative`. However, that only works if there's an active handler
on that element; this made a quick consecutive call:
```js
elem.on( "focus", function() {} ).off( "focus" );
```
make subsequent `.trigger( "focus" )` calls to not do any triggering.
The solution, already used in a similar `_default` method for the `click` event,
is to check for the `dataPriv` entry on the element for the focus event
(similarly for blur).

* the test is now using a correct "text/javascript" Content-Type; it was using

Changes:

* Change `firstCall.lastArg` to `firstCall.args[ 0 ]` as the former API is not

If during a focus handler another focus event is triggered:
```js
elem1.on( "focus", function() {
elem2.trigger( "focus" );
} );
```
due to their synchronous nature everywhere outside of IE the hack added in
gh-4279 to leverage native events causes the native `.focus()` method to be
called last for the initial element, making it steal the focus back. Since
the native method is already being called in `leverageNative`, we can skip that
final call.
This aligns with changes to the `_default` method for the `click` event that
were added when `leverageNative` was introduced there.
A side effect of this change is that now `focusin` will only propagate to the
document for the last focused element. This is a change in behavior but it also
aligns us better with how this works with native methods.

In Chrome, if an element having a `focusout` handler is blurred by
clicking outside of it, it invokes the handler synchronously. If
that handler calls `.remove()` on the element, the data is cleared,
leaving private data undefined. We're reading a property from that
data so we need to guard against this.

Issue gh-4379 was meant to be a bug fix but the JSONP case is a bit special:
under the hood it's a script but it simulates JSON responses in an environment
without a CORS setup and sending JSON payloads on error responses is quite
typical there.
This commit makes JSONP error responses still execute the payload. The regular
script error responses continue to be skipped.

(cherry picked from commit 11066a9e6a)
The "jQuery.ajax() - JSONP - Same Domain" test is firing a request with
a duplicate "callback" parameter, something like (simplified):
```
mock.php?action=jsonp&callback=jQuery_1&callback=jQuery_2
```
There was a difference in how the PHP & Node.js implementations of the jsonp
action in the mock server handled situations like that. The PHP implementation
was using the latest parameter while the Node.js one was turning it into an
array but the code didn't handle this situation. Because of how JavaScript
stringifies arrays, while the PHP implementation injected the following code:
```js
jQuery_2(payload)
```
the Node.js one was injecting the following one:
```js
jQuery_1,jQuery_2(payload)
```
This is a comma expression in JavaScript; it so turned out that in the majority
of cases both callbacks were identical so it was more like:
```js
jQuery_1,jQuery_1(payload)
```
which evaluates to `jQuery_1(payload)` when `jQuery_1` is defined, making the
test go as expected. In many cases, though, especially on Travis, the callbacks
were different, triggering an `Uncaught ReferenceError` error & requiring
frequent manual re-runs of Travis builds.
This commit fixes the logic in the mock Node.js server, adding special handling
for arrays.

The main part of the test was checking that focusin handling in an iframe works
and that's still checked. The test was also checking that it doesn't propagate
to the parent document, though, and, apparently, in IE it does. This one test
is now blacklisted in IE.
The `doc` variable in:
https://github.com/jquery/jquery/blob/3.4.1/src/event/focusin.js#L30
matched `document` for `document` & `window` for `window`, creating two
separate wrapper event handlers & calling handlers twice if at least one
`focusout` or `focusin` handler was attached on *both* `window` & `document`,
or on `window` & another regular node.
Also, fix the "focusin from an iframe" test to actually verify the behavior
from commit 1cecf64e5a - the commit that
introduced the regression - to make sure we don't regress on either front.
