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
So far, only browser-based JS files were required to be in strict mode (in the
function form). This commit adds such a requirement to Node.js scripts where
the global form is preferred. All Node.js scripts in sloppy mode were
converted to strict mode.
Closes gh-4499
So far, we've been testing that jQuery element iteration works with polyfilled
Symbol & transpiled for-of via a Node test with jsdom with the Symbol global
removed. Unfortunately, jsdom now requires Symbol to be present for its internal
functionality so such a test is no longer possible. Instead, it's been migrated
to an iframe test with transpiled JavaScript.
This PR also enables us to use ECMAScript 2017 or newer in Node.js code.
Closes gh-4305
jsdom 3 requires Python & Visual Studio on Windows which is a significant
barrier to contributors. Newer jsdom versions don't require pre-compiling
but work only on io.js. This commit installs the new jsdom everywhere (it
does install in old Node.js, it just won't work) and executes Node-related
tests only on newer Nodes or if a working jsdom version is installed. The
latter can be achieved by running the `old_jsdom` task.
Node.js is merging with io.js soon so this will become a smaller problem over
time.
One drawback is our Jenkins setup runs on Node 0.10 so it won't be running
Node tests anymore. We have Travis set up on io.js, though so all PRs
have those tests run. When the new LTS Node.js arrives (as it soon merges
with io.js) we should update our Jenkins infrastructure so that it runs on this
new version.

Make iterating over jQuery objects possible using ES 2015 for-of:
for ( node of $( "<div id=narwhal>" ) ) {
console.log( node.id ); // "narwhal"
}
Fixes gh-1693
There is a lot of logic in intro.js; now we test four cases:
1. (implicitly, via QUnit tests) A real browser with window being the global
2. Browserify where there are both global & window variables.
3. Node with jsdom where window is passed manually to the jQuery factory.
4. Pure Node with incorrect window passed; jQuery should throw then.
Previously the second & fourth case was not tested and the third was tested
in a way that interfered with the main test environment.
We now also test if in the Browserify case we're not creating a jQuery global
by default.
Fixes gh-2181
Closes gh-2234
