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.

iOS 8-12 parses `<noembed>` tags differently, executing this code. This is no
different to native behavior on that OS, though, so just accept it.

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.

Make sure events & data keys matching Object.prototype properties work.
A separate fix for such events on cloned elements was added as well.

1. Support passing custom document to jQuery.globalEval; the script will be
invoked in the context of this document.
2. Fire external scripts appended to iframe contents in that iframe context;
this was already supported & tested for inline scripts but not for external
ones.

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
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.
Closes gh-4577
Remove the workaround for a broken `:enabled` pseudo-class on anchor elements
in Chrome <=77. These versions of Chrome considers anchor elements with the
`href` attribute as matching `:enabled`.

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.

qSA in IE 11/Edge often (but not always) don't find elements with an empty
name attribute selector (`[name=""]`). Detect that & fall back to Sizzle

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

Sizzle's PR jquery/sizzle#456 introduced a test catching not throwing on
badly-escaped identifiers by Firefox 3.6-5. Unfortunately, it was placed just
before a test Opera 10-11 failed, making Opera fail quicker and not adding
a post-comma invalid selector to rbuggyQSA.
The issue was fixed in jquery/sizzle#463. This jQuery commit backports the test
that Sizzle PR added as no workarounds are needed in browsers jQuery supports.

The script transport used to evaluate fetched script sources which is
undesirable for unsuccessful HTTP responses. This is different to other data
types where such a convention was fine (e.g. in case of JSON).

Calling `Array.prototype.concat.apply( [], inputArray )` to flatten `inputArray`
crashes for large arrays; using `Array.prototype.flat` avoids these issues in
browsers that support it. In case it's necessary to support these large arrays
even in older browsers, a polyfill for `Array.prototype.flat` can be loaded.
This is already being done by many applications.

`:even` & `:odd` are deprecated since jQuery 3.4.0 & will be removed in 4.0.0.

With new selector code doing less convoluted support tests, it was possible

during a switch from JSHint + JSCS to ESLint.

The `:scope` pseudo-class[1] has surprisingly good browser support: Chrome,
Firefox & Safari have supported if for a long time; only IE & Edge lack support.
This commit leverages this pseudo-class to get rid of the ID hack in most cases.
Adding a temporary ID may cause layout thrashing which was reported a few times
in [the past.
We can't completely eliminate the ID hack in modern browses as sibling selectors
require us to change context to the parent and then `:scope` stops applying to
what we'd like. But it'd still improve performance in the vast majority of
cases.

This commit removes Sizzle from jQuery, inlining its code & removing obsolete
workarounds where applicable.
The selector-native module has been removed. Further work on the selector
module may decrease the size enough that it will no longer be necessary. If
it turns out it's still useful, we'll reinstate it but the code will look
different anyway as we'll want to share as much code as possible with
the existing selector module.
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 commit reduces the gzipped jQuery size by 1460 bytes compared to master.
Closes gh-4395
Apart from porting most Sizzle tests to jQuery (mostly to its selector module),
this commit fixes selector-native so that a jQuery custom compilation that
excludes Sizzle passes all tests as well.

Latest versions of all browsers now implement focusin & focusout natively
and they all converged on a common event order so it doesn't make much sense
for us to normalize it to a different order anymore.
Note that it means we no longer guarantee that focusin fires before focus
and focusout before blur.
Fixes gh-4300
Closes gh-4362
The camelCase implementation used by the data module no longer turns `-ms-foo`
into `msFoo` but to `MsFoo` now. This is because `data` is supposed to be
a generic utility not specifically bound to CSS use cases.

Android Browser disregards td's box-sizing, treating it like it was content-box.
Unlike in IE, offsetHeight shares the same issue so there's no easy way to
workaround the issue without incurring high size penalty. Let's at least check
we get the size as the browser sees it.
Also, fix the nearby support comment syntax.

Android Browser versions provided by BrowserStack fail the "prototype collision
(constructor)" test while locally fired emulators don't, even when they connect

Summary of the changes/fixes:
1. Trigger checkbox and radio click events identically (cherry-picked from
b442abacbb that was reverted before).
2. Manually trigger a native event before checkbox/radio handlers.
3. Add test coverage for triggering namespaced native-backed events.
4. Propagate extra parameters passed when triggering the click event to
the handlers.
5. Intercept and preserve namespaced native-backed events.
6. Leverage native events for focus and blur.
7. Accept that focusin handlers may fire more than once for now.
