After recent merging of Sizzle & jQuery AUTHORS.txt, the `grunt authors` task
doesn't provide meaningful as there's no obvious connection between current
AUTHORS.txt contents & the desired one. Adding two new entries should make it
easier (plus, it makes it possible to test jquery-release on current master).
Apart from that, the commit adds a missing .mailmap entry for Shashanka Nataraj.
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).
Fixes gh-4250
Closes gh-4379
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.
Fixes gh-4320
Closes gh-4459
IE/Edge sometimes crash when comparing documents between frames using the strict
equality operator (`===` & `!==`). Funnily enough, shallow comparisons
(`==` & `!=`) work without crashing.
Fixes gh-4441
Closes gh-4471
`:even` & `:odd` are deprecated since jQuery 3.4.0 & will be removed in 4.0.0.
The new `even()` & `odd()` methods will make the migration easier.
Closes gh-4485
With new selector code doing less convoluted support tests, it was possible
to extract a lot of logic out of setDocument & also reduce size.
This commit also backports jquery/sizzle#439 that was reverted by mistake
during a switch from JSHint + JSCS to ESLint.

Previously, jQuery.ajaxSettings.xhr, contents were wrapped in a try-catch
as we defined jQuery.support.ajax & jQuery.support.cors executed during the
jQuery load and we didn't want to crash if IE had native XHR disabled (which
is possible). While jQuery hasn't supported the ActiveX-based XHR since 2.0,
jQuery with XHR disabled could still be used for its other features in such
a crippled browser.
Since gh-4347, jQuery.support.ajax & jQuery.support.cors no longer exist, so
we don't need the try-catch anymore.

Now that Sizzle is gone & we use npm, we can read from node_modules directly
and skip the setup that copies some files to the external directory.
Closes gh-4466
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.

A copied comment line was accidentally left out above the line defining

Due to a faulty IE 8 workaround removal, the fast path qSA mode was skipped
when jQuery's find was called on an element node - i.e. in most 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.
Closes gh-4406
This commit requires all function parameters to be used, not just the last one.
In cases where that's not possible as we need to match an external API, there's
an escape hatch of prefixing an unused argument with `_`.
This change makes it easier to catch unused AMD dependencies and unused
parameters in internal functions the API of which we may change at will, among
other things.
Unused AMD dependencies have been removed as part of this commit.
Closes gh-4381
The previous regex caused the final jQuery binary to have syntax errors for
var-modules with names starting with "return". For example, the following module
wouldn't work when the file is named `returnTrue.js`:
```js
define( function() {
"use strict";
return function returnTrue() {
return true;
};
} );
```
Closes gh-4389
The original fix didn't account for the fact that in IE `<object>` elements
with no `data` attribute have an object `contentDocument`. The fix leverages
the fact that this special object has a null prototype.

Because of the above conditional, the 'type' variable has a value of type
'string' or undefined. Therefore, boolean comparisons for 'type' variable
is always unnecessary because it return true. The patch removed the
unnecessary conditional statement.
Fixes gh-4374
Closes gh-4375
A leftover `rboxStyle` was left in the wrapper parameters but not in the
dependency array, causing `getStyles` to be undefined in AMD mode.
Since `rboxStyle` is no longer used, it's now removed.

Closes gh-4380
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.

Also, prevent further similar breakages by changing our ESLint configuration
to disallow relying on a global jQuery object in AMD modules.

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.
Closes gh-4335
Android Browser versions provided by BrowserStack fail the "prototype collision
(constructor)" test while locally fired emulators don't, even when they connect
to TestSwarm. Just skip the test there to avoid a red build.

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.
