This commit removes Sizzle from jQuery, inlining its code & removing obsolete
workarounds where applicable.
The Sizzle AUTHORS.txt file has been merged with the jQuery one - people are
sorted by their first contributions to either of the two repositories.
The main `selector` module can be disabled in favor of `selector-native`
via:
grunt custom:-selector
For backwards compatibility, the legacy `sizzle` alias is also supported (it
will be dropped in jQuery `4.0.0`):
grunt custom:-selector
Sizzle tests have been ported to jQuery ones. Ones that are not compatible
with the `selector-native` module are disabled if the regular selector module
is excluded.
Backwards compatibility is still kept for all `Sizzle` utils - they continue to be
available under `jQuery.find` - but the primary implementation is now attached
directly to jQuery.
Some selector utils shared by `selector` & `selector-native` have been
extracted & deduplicated. `jQuery.text` and `jQuery.isXMLDoc` have been
moved to the `core` module.
The commit reduces the gzipped jQuery size by 851 bytes compared to the
`3.x-stable` branch.

The `<template/>` element `contents` property is a document fragment that may
have a `null` `documentElement`. In Safari 16 this happens in more cases due
to recent spec changes - in particular, even if that document fragment is
explicitly adopted into an outer document. We're testing both of those cases
now.
The crash used to happen in `jQuery.contains` which is an alias for
`Sizzle.contains` in jQuery 3.x.
The Sizzle fix is at jquery/sizzle#490, released in Sizzle `2.3.8`. This
version of Sizzle is included in the parent commit.
A fix similar to the one from gh-5158 has also been applied here to the
`selector-native` version.

The previous details were showing their age, e.g. mentions about browsers
not supporting ES2015. The story with ES modules is more complex as it's also
about loaders but to keep the README simple, let's just make it more up to date
with typical usage.

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.

Accept "HTTP/2.0 200" as a valid `statusText` for successful requests
to make ajax tests pass in iOS 9. At this point, normalizing this in code
doesn't seem to make a lot of sense.
Closes gh-5121
Regex imp implementation takes `O(N^2)` time to trim the string when
multiple adjacent spaces were present.
The new expression require that the "whitespace run" starts from
a non-whitespace to avoid `O(N^2)` behavior when the engine would
try matching `\s+$` at each space position.
Closes gh-5068
Introduces a new test API, `includesModule`. The method returns whether
a particular module like "ajax" or "deprecated" is included in the current
jQuery build; it handles the slim build as well. The util was created so that
we don't treat presence of particular APIs to decide whether to run a test as
then if we accidentally remove an API, the tests would still not fail.

This adds testing on Node.js 17 in addition to the currently tested 10, 12, 14
and 16 versions.
Also, update Grunt & `karma-*` packages.
Testing in Karma on jsdom is broken in Node 17 at the moment; until we find
a fix, this change disables such testing on Node 17 or newer.
Node smoke tests & promises aplus tests are disabled on Node.js 10 as they
depend on jsdom and the latest jsdom version doesn't run properly on Node 10.

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.

Neither of the removed links is crucial; one of them refers to a site that has

TestSwarm is now proxied via Cloudflare which cuts out headers relevant for
ETag tests, failing them. We're still running those tests in Karma on Chrome
& Firefox (including Firefox ESR).

(cherry picked from commit 00c060d161)
In HTTP/2, status message is not supported and whatever is reported as
statusText differs between browsers. In Chrome & Safari it's "success", in
Firefox & IE it's "OK". So far "success" wasn't allowed. This made the tests
pass locally if you're running an HTTP/1.1 server but on TestSwarm which is
now proxied via an HTTP/2-equipped Cloudflare, the relevant test started failing
in Chrome & Safari.
Allow "success" to resolve the issue.

Since the default Karma browser no activity timeout was lower than the QUnit
timeout, a single timing out test was interrupting the whole test run of
a browser.
The QUnit timeout is set to 1 minute so I set the Karma one to 2 minutes.

The EasyCLA status check is required so this won't get missed. The old JSF CLA
is dead, the provided link doesn't return meaningful information. There's no
good replacement link for the old CLA; PR authors are just supposed to sign the

first PR since EasyCLA was enabled for the repo.

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.
