According to the docs, one can use `null` as a success function in `jQuery.get`
of `jQuery.post` so the following:
```js
await jQuery.get( "https://httpbin.org/json", null, "text" )
```
should get the text result. However, this shortcut hasn't been working so far.

We've already had `buildFragment` extracted to a separate file long ago.
`domManip` is quite a complex & crucial API and so far it has existed within
the `manipulation.js` module. Extracting it makes the module shorter and easier
to understand.
A few comments / messages in tests have also been updated to not suggest there's
a public `jQuery.domManip` API - it's been private since 3.0.0.
Closes gh-5138
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.

PR gh-4993 changed a few too many issue references to `trac-NUMBER` ones. This
change fixes them. It also fixes a typo in one Trac issue number in selector
tests.
Ref gh-4993
Closes gh-4995
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.
Closes gh-4993
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).
Closes gh-4974
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.
Closes gh-4973
PR gh-2588 made jQuery stop auto-execute cross-domain scripts unless
`dataType: "script"` was explicitly provided; this change landed in jQuery
3.0.0. This change extends that logic same-domain scripts as well.
After this change, to request a script under a provided URL to be evaluated,
you need to provide `dataType: "script` in `jQuery.ajax` options or to use
`jQuery.getScript`.

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

Drop support for Edge Legacy: the non-Chromium, EdgeHTML-based Microsoft
Edge version. Also, restrict some workarounds that were applied
unconditionally in all browsers to run only in IE now. This slightly
increases the size but reduces the performance burden on modern browsers
that don't need the workarounds.
Also, clean up some comments & remove some obsolete workarounds.
Fixes gh-4568

The test has been already skipped in Chrome as it dropped support for such
requests and now Safari has joined the squad.
This will resolve AJAX test errors we've had for a while in Safari 13 & iOS 13.
Closes gh-4779
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.
Fixes gh-4771
Closes gh-4773
Until now, the AJAX script transport only used a script tag to load scripts
for cross-domain requests or ones with `scriptAttrs` set. This commit makes
it also used for all async requests to avoid CSP errors arising from usage
of inline scripts. This also makes `jQuery.getScript` not trigger CSP errors
as it uses the AJAX script transport under the hood.
For sync requests such a change is impossible and that's what `jQuery._evalUrl`
uses. Fixing that is tracked in gh-1895.
The commit also makes other type of requests using the script tag version of the
script transport set its type to "GET", namely async scripts & ones with
`scriptAttrs` set in addition to the existing cross-domain ones.
Fixes gh-3969
Closes gh-4763
Previously, `jQuery.ajax` with `dataType: 'json'` with a provided callback was
automatically converted to a jsonp request unless one also specified
`jsonp: false`. Today the preferred way of interacting with a cross-domain
backend is CORS which works in all browsers jQuery 4 will support.
Auto-promoting JSON requests to JSONP ones introduces a security issue as the
developer may be unaware they're not just downloading data but executing code
from a remote domain.
This commit disables the auto-promoting logic.
BREAKING CHANGE: to trigger a JSONP request, it's now required to specify
`dataType: "jsonp"`; previously some requests with `dataType: "json"` were
auto-promoted to JSONP.

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
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).

Android Browser versions provided by BrowserStack fail the "prototype collision

Also, run `grunt npmcopy` to sync the "external" directory with dependencies

- getResponseHeader(key) combines all header values for the provided key into a
single result where values are concatenated by ', '. This does not happen for
IE11 since multiple values for the same header are returned on separate lines.
This makes the function only return the last value of the header for IE11.

The added unit test shows how this could be used to support an
ArrayBuffer return, but $.ajax does not support it natively.
The goal with this change was to avoid the exception.
