The `_default` function in the special event settings for focus/blur has
always returned `true` since gh-4813 as the event was already being fired
from `leverageNative`. However, that only works if there's an active handler
on that element; this made a quick consecutive call:
```js
elem.on( "focus", function() {} ).off( "focus" );
```
make subsequent `.trigger( "focus" )` calls to not do any triggering.
The solution, already used in a similar `_default` method for the `click` event,
is to check for the `dataPriv` entry on the element for the focus event
(similarly for blur).

Only allow alphanumeric characters & underscores for callback parameters.
The change is done both for the PHP server as well as the Node.js-based version.
This is only test code so we're not fixing any security issue but it happens
often enough that the whole jQuery repository directory structure is deployed
onto the server with PHP enabled that it makes is easy to introduce security
issues if this cleanup is not done.

Two issues are fixed in testing for responses with a script Content-Type not
getting auto-executed unless an explicit `dataType: "script"` is provided:
* the test is now using a correct "text/javascript" Content-Type; it was using
"text/html" until now which doesn't really check if the fix works
* the Node.js based version of the tests didn't account for an empty `header`
query string parameter

Legacy Edge, similarly to IE, doesn't report XML parsing errors but just tries

Changes:
* Remove incorrect `QUnit.testUnlessIE` usage as that util is only available
on `master`, not here.
* Change `firstCall.lastArg` to `firstCall.args[ 0 ]` as the former API is not
available in older Sinon versions.
If during a focus handler another focus event is triggered:
```js
elem1.on( "focus", function() {
elem2.trigger( "focus" );
} );
```
due to their synchronous nature everywhere outside of IE the hack added in
gh-4279 to leverage native events causes the native `.focus()` method to be
called last for the initial element, making it steal the focus back. Since
the native method is already being called in `leverageNative`, we can skip that
final call.
This aligns with changes to the `_default` method for the `click` event that
were added when `leverageNative` was introduced there.
A side effect of this change is that now `focusin` will only propagate to the
document for the last focused element. This is a change in behavior but it also
aligns us better with how this works with native methods.

In Chrome, if an element having a `focusout` handler is blurred by
clicking outside of it, it invokes the handler synchronously. If
that handler calls `.remove()` on the element, the data is cleared,
leaving private data undefined. We're reading a property from that
data so we need to guard against this.

This aligns the Node.js server with the previous PHP one in sending `mock.php`
as a callback if there's no `callback` parameter in the query string which is
triggered by a recently added test. This prevents the request crashing on that
Node.js server and printing a JS error:
```
TypeError: Cannot read property '1' of null
```

Issue gh-4379 was meant to be a bug fix but the JSONP case is a bit special:
under the hood it's a script but it simulates JSON responses in an environment
without a CORS setup and sending JSON payloads on error responses is quite
typical there.
This commit makes JSONP error responses still execute the payload. The regular
script error responses continue to be skipped.

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.

The change in gh-4603 made the object returned by `elem.data()`
a prototype-less object. That's a desired change to support keys
colliding with `Object.prototype` properties but it's also a breaking
change so it has to wait for jQuery 4.0.0.
A 3.x-only test was added to avoid breaking it in the future on this
branch.
