This also resolves a security warning from GitHub about a vulnerable `request`
version - the new `testswarm` package version depends on a fixed `request`.

Concatenating HTML strings in buildFragment is a possible security risk as it
creates an opportunity of escaping the concatenated wrapper. It also makes it
impossible to support secure HTML wrappers like
[trusted types](https://web.dev/trusted-types/). It's safer to create wrapper
elements using `document.createElement` & `appendChild`.
The previous way was needed in jQuery <4 because IE <10 doesn't accept table
parts set via `innerHTML`, even if the element which contents are set is
a proper table element, e.g.:
```js
tr.innerHTML = "<td></td>";
```
The whole structure needs to be passed in one HTML string. jQuery 4 drops
support for IE <11 so this is no longer an issue; in older version we'd have
to duplicate the code paths.
IE <10 needed to have `<option>` elements wrapped in
`<select multiple="multiple">` but we no longer need that on master which
makes the `document.createElement` way shorter as we don't have to call
`setAttribute`.
All these improvements, apart from making logic more secure, decrease the
gzipped size by 58 bytes.

The issue about selectors with '#' being broken is old and no longer
frequently reported so this commit removes it from the list. On the other
hand, we're now getting lots of reports about the security fix in jQuery 3.5.0
that was also a breaking change: gh-4642. This one is now mentioned in the
list.

To achieve that, use `eslint-plugin-import`'s `no-unused-modules` rule.
Also, explicitly import `event/trigger.js` from `jquery.js`; so far it was
only imported from ajax.js, making it mistakenly skipped in the
`custom:slim,-deprecated` build.

This commit cleans up a few comments & configurations that are out of date
after the migration to ES modules backed by a Rollup-based compilation.
Also, de-indent AMD modules. This will preserve a more similar
structure to the one on 3.x-stable where the body of the main `define`
wrapper is not indented.

The `show()`, `hide()` & `toggle()` methods were included in the 3.x jQuery
slim build. The jQuery master build accidentally started to exclude them as
they were only imported in the effects module and the new Rollup-based build
system follows the module dependency graph when excluding modules.
To resolve the issue, import the `css/showHide.js` file directly in the main
`jquery.js` file.

So far, the slim build was expanded to its full exclusion list, generating the
following `jQuery.fn.jquery`:
```
v4.0.0-pre -ajax,-ajax/jsonp,-ajax/load,-ajax/script,-ajax/var/location,-ajax/var/nonce,-ajax/var/rquery,-ajax/xhr,-manipulation/_evalUrl,-deprecated/ajax-event-alias,-callbacks,-deferred,-deferred/exceptionHook,-effects,-effects/Tween,-effects/animatedSelector,-queue,-queue/delay,-core/ready
```
This commit changes it to just `v4.0.0-pre slim`. Only the pure slim build is
treated this way, any modification to it goes through the old expansion; e.g.
for `custom:slim,-deprecated` we get the following `jQuery.fn.jquery`:
```
v4.0.0-pre -deprecated,-deprecated/ajax-event-alias,-deprecated/event,-ajax,-ajax/jsonp,-ajax/load,-ajax/script,-ajax/var/location,-ajax/var/nonce,-ajax/var/rquery,-ajax/xhr,-manipulation/_evalUrl,-callbacks,-deferred,-deferred/exceptionHook,-effects,-effects/Tween,-effects/animatedSelector,-queue,-queue/delay,-core/ready
```
Since the version string is also put in the jQuery header comment, it also got
smaller.
Also, the logic to skip including the commit hash in the header comment - when
provided through the COMMIT environment variable which we do in Jenkins - in
minified builds headers has been applied to builds with exclusions as well.

Backport tests from a jQuery 3.x fix that's not needed on `master`.
Also, fix the "focusin from an iframe" test to actually verify the behavior
from commit 1cecf64e5aa415367a7dae0b55c2dd17b591442d - the commit that
introduced the regression - to make sure we don't regress on either front.
The main part of the modified 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 "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.

So far, the slim build only excluded ajax & effects modules. As many web apps
right now rely on native Promises, often with a polyfill for legacy browsers,
deferred & callbacks modules are not that useful for sites that already exclude
ajax & effects modules.
This decreases the gzipped minified size of the slim module by 1760 bytes,
to 19706 bytes (below 20k!).

Before this change, `val()` was stripping out carriage return characters from
the returned value. No test has relied on that. The logic was different for
option elements as its custom defined hook was omitting this stripping logic.
This commit gets rid of the carriage return removal and isolates the IE-only
select val getter to be skipped in other browsers.

PR gh-4550 added support for running ES modules & AMD tests via Karma. This
required reading the `esmodules` & `amd` props from both `QUnit.config` &
`QUnit.urlParams`. By picking these two properties manually, the `dev` one
stopped being respected while ones handled directly by QUnit were fine (like
`hidepassed`). Instead of maintaining the full list of options, the code now
iterates over QUnit URL config and handles the fallbacks in a more generic way.
Apart from that, all jQuery source & test files are now read directly from disk
instead of being cached by Karma so that one can run `grunt karma:chrome-debug`
& work on a fix without restarting that Karma run after each change. A similar
effect could have been achieved by setting `autoWatch` to `true` but then the
main Karma page runs tests in an iframe by default when
`grunt karma:chrome-debug` is run instead of relying on the current debug flow.
