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.
Closes gh-4649
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 1cecf64e5a - 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.

Use a dist README fixture kept in the jQuery repository instead of modifying
an existing one. This makes the jQuery repository the single source of truth
when it comes to jQuery releases and it makes it easier to make changes to
README without worrying how it will affect older jQuery lines.
The commit also ES6ifies build/release.js & build/release/dist.js

Node.js code is written more & more commonly in ES6+ so it doesn't make sense

1. Support passing custom document to jQuery.globalEval; the script will be

A new `src/deprecated` directory makes it possible to exclude some deprecated

The consequence is `.css( "opacity" )` will now return an empty string for
detached elements in standard-compliant browsers and "1" in IE & the legacy

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.
Closes gh-4585
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.

This commit fixes unit tests for the following builds:
1. The no-deprecated build: `custom:-deprecated`
2. The current slim build: `custom:-ajax,-effects`
3. The future (#4553) slim build: `custom:-ajax,-callbacks,-deferred,-effects`
It also adds separate Travis jobs for the no-deprecated & slim builds.

jQuery source has been migrated in gh-4541 from AMD to ES modules. To maintain
support for consumers of our AMD modules, this commits adds a task transpiling
the ES modules sources in `src/` to AMD in `amd/`.
A "Load with AMD" checkbox was also restored to the QUnit setup. Note that,
contrary to jQuery 3.x, AMD files need to be generated via `grunt amd` or
`grunt` as sources are not authored in ECMAScript modules. To achieve a similar
no-compile experience during jQuery 4.x testing, use the new "Load as modules"
checkbox which works in all supported browsers except for IE & Edge (the
legacy, EdgeHTML-based one).

There was a check in jQuery.event.add that was supposed to make it a noop
for objects that don't accept data like text or comment nodes. The problem was
the check was incorrect: it assumed `dataPriv.get( elem )` returns a falsy
value for an `elem` that doesn't accept data but that's not the case - we get
an empty object then. The check was changed to use `acceptData` directly.

This commit gets rid of rollup-plugin-hypothetical in favor of a simpler
inline Rollup plugin that fits our need and is compatible with Windows.
Fixes gh-4548
Closes gh-4549
jQuery source is now authored in ECMAScript modules. Native browser support
for them requires full file names including extensions. Rollup works even
if import paths don't specify extensions, though, so one import slipped
through without such an extension, breaking native browser import of
src/jquery.js.
A new ESLint rule using eslint-plugin-import prevents us from regressing
on that front.
Also, eslint-plugin-import's no-cycle rule is used to avoid import cycles.

qSA in IE 11/Edge often (but not always) don't find elements with an empty

traversal.
Interestingly, IE 10 & older don't seem to have the issue.

Migrate all source AMD modules to ECMAScript modules. The final bundle
is compiled by a custom build process that uses Rollup under the hood.
Test files themselves are still loaded via RequireJS as that has to work in
IE 11.
Tests can now be run in "Load as modules" mode which replaces the previous
"Load with AMD" option. That option of running tests doesn't work in IE
and Edge as it requires support for dynamic imports.
Some of the changes required by the migration:
* check `typeof` of `noGlobal` instead of using the variable directly
as it's not available when modules are used
* change the nonce module to be an object as ECMASscript module exports
are immutable
* remove some unused exports
* import `./core/parseHTML.js` directly in `jquery.js` so that it's not
being cut out when the `ajax` module is excluded in a custom compilation
Closes gh-4541
Also, run them on both ChromeHeadless & FirefoxHeadless locally on

IE/Edge sometimes crash when comparing documents between frames using the strict
equality operator (`===` & `!==`). Funnily enough, shallow comparisons
(`==` & `!=`) work without crashing.
The change to shallow comparisons in `src/selector.js` was done in gh-4471 but
relevant changes in `src/selector/uniqueSort.js` were missed. Those changes
have landed in Sizzle in jquery/sizzle#459.
