Functional changes:
- Require page URL when constructing a PreviewModel null object. These
models have valid titles and are used to display a preview when an
extract is unobtainable. When presented with an empty URL, their
linkage incorrectly pointed to the browser's current URL. Additional
tests were added to verify the fix.
- Check missing title in addition to falsy response in RESTBase gateway
and update the test assertion to check title. It isn't clear if this
can happen in the wild.
- Forbid state mutation in the conclusion of
MediaWikiGateway.getPageSummary() with a call to Deferred.promise().
This is consistent with the rest of repo including RESTBaseGateway.
http://api.jquery.com/deferred.promise/
Nonfunctional changes:
- Collapse two RESTBase gateway 404 tests into one as the scenarios and
expectations were very similar.
- Add failure HTTP status to 'MediaWiki API gateway handles API failure'
test stub HTTP response for consistency with other cases.
- Add nullity expectations to JSDocs touched and fix a couple typos
throughout.
- Make the gateway tests a little more consistent by collapsing Deferred
variable usage where appropriate.
This change is necessary to the completion of T183151 which uses the
PreviewModel null objects for additional error cases.

Introduce PopupsAnonsExperimentalGroupSize config variable. This defines
a population size who will be subject to experimentation. If the group
size is undefined or 0 (default) and PopupsBetaFeature is false
(default value) Popups will be enabled for everyone. If it is any other
value, half that group will see page previews.
Drop the config variable PopupsSchemaSamplingRate - we will now only
EventLog when an experiment is occuring. This means we can simplify the
MWEventLogger class as shouldLog will always be truthy. Given server
side eventlogging is only used for preference changes
traffic should be low and not need sampling.
Introduce getUserBucket which determines whether a user is in a bucket
on, off or control based on the value of
PopupsAnonsExperimentalGroupSize. Add tests showing how these
buckets are calculated.
Caution:
A kill switch wgPopupsEventLogging is provided for safety.
It defaults to false. Before merging, please check if any config changes
are necessary.

Why: Because they are the approved standard by TC39 and Ecma for
JavaScript modules.
Changes:
* Wrap mw-node-qunit in run.js to register babel to transpile modules
for node v6
* Change all sources in src/ to use ES modules
* Change constants.js to be able to run without
jQuery.bracketedDevicePixelRatio given ES modules are hoisted to
the top by spec so we can't patch globals before importing it
* Change all tests in tests/node-qunit/ to use ES modules
* Drop usage of mock-require given ES modules are easy to stub with
sinon
Additional changes:
* Rename tests/node-qunit/renderer.js to renderer.test.js to follow
the convention of all the other files
* Make npm run test:node run only .test.js test files so that it
doesn't run the stubs.js or run.js file.

This reduces the number of 301 Redirect responses when fetching previews
from RESTBase.

Action changes:
* Include the namespace ID in LINK_DWELL.
Reducer changes:
* Add the createEvent helper, which adds the pageTitleHover and
namespaceIdHover properties in the event.
* Create "dismissed", "dwelledButAbandoned", and "opened" events using
the createEvent helper.
Additional changes:
* Store the target page's associated mw.Title using jQuery.
* Update the eventLogging reducer's test cases so that all LINK_DWELL
representations include title and namespaceID attributes.
* Create the createStubTitle factory function, which returns a minimal
usable mw.Title stub, and use it in the actions and integration test
cases.

Tests are basically unchanged, except for some stubs on beforeEach.
Supporting changes:
* Bring stubs from the mediawiki library for mw.Uri,
mw.Title.newFromText and mw.RegExp into stubs.js
* Remove hook onResourceLoaderTestModules given there are no resource
loader test modules after migrating processLinks.test.js
Why bring stubs from real source? This is not optimal. It could be the
case that the stubs would need to be updated at some point in the
future. That's why in the comment of each stub, it is specified where it
came from, and what was changed to make it work. It is not optimal but
it should help with a future update if necessary.
Also checked the history of the stubs and these three stubs are very
stable with a small commits per year, usually adding some extra
functionality (not breaking changes) (the rest of the commits are
docs/format stuff), so the core behavior that we rely on here shouldn't
change in a fundamental way. See the github links:
* https://github.com/wikimedia/mediawiki/commits/master/resources/src/mediawiki/mediawiki.Uri.js
* https://github.com/wikimedia/mediawiki/commits/master/resources/src/mediawiki/mediawiki.Title.js
* https://github.com/wikimedia/mediawiki/commits/master/resources/src/mediawiki/mediawiki.RegExp.js
Right now this stubs allow us to bring the test to run in isolation in
node.
The initial plan was to do change the test to be less test-case oriented
with dependencies on mediawiki.*.js and not to bring fake "real" stubs,
but after looking into it, given that:
1. the test cases in the test seem pretty informative showing the kind
of links that popups accepts
2. the stubs are acceptably easy to bring in, and are pretty stable
I decided to go with this approach initially to finish the migration
without changing the meaning of the tests.
If we want to remove the stubs and morph the test to verify stub calls
and move the test cases to documentation on the source, I'll tackle that
on a future commit.

For logging to work:
1. $wgWMEStatsdBaseUri needs to point to a valid statsv endpoint,
e.g. 'https://en.wikipedia.org/beacon/statsv'.
2. $wgPopupsStatsvSamplingRate needs to be set. Note that the codebase
already contains the EventLogging functionality, which is configured
separately. Separately configuring different logging mechanisms
allows us to avoid sampling mistakes that may arise while choosing
one or the other. For example, let's say we want to use EventLogging for
10% of users and statsv for 5%. We'd sample all users into two
buckets: 50/50. And then we'd have to set the sampling rates as
20% and 10% respectively, only because of the bucketing above. To avoid
this kind of complications, separate sampling rates are used for each
logging mechanism. This, of course, may result in situations where a
session is logged via both EventLogging and statsv.
3. The WikimediaEvents extension needs to be installed. The extension
adds the `ext.wikimediaEvents` module to the output page. The
logging functionality is delegated to this module.
Notable changes:
* The FETCH_START and FETCH_END actions are converted to a timed action.
* The experiments stub used in tests has been extracted to the stubs
file.
