Piotr Miazga f2fbef6ec7 Implement html/rest.js gateway which handles HTML Restbase responses
Refactor existing Restbase gateway and extract shared logic into
shared Restbase provider. Also introduced new createNullModel()
which defines an empty preview model.

Additionally improve naming in new gateways/formatter so function
names are more explicity.
 * Htmlize() became formatPlainTextExtract() as it should be used
   only with plain text extracts
 * removeEllipsis() became  removeTrailingEllipsis() as it removes
   only trailing ellipsis.
 * src/gateway/index.js defines gateways by configuration name stored
   in extension.json

joakin c9d325d01e Tests: Migrate processLinks.test.js to node-qunit
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.

Sam Smith d55e8b9a17 Don't load entire codebase in QUnit tests
As noted in T160406, the only QUnit tests that requires a running
MediaWiki instance is the test for mw.popups.processLinks. The function
itself is isolated from the rest of the codebase.

Now, as noted in T162876#3182198, during boot the
ext.eventLogging.Schema module is loaded asynchronously with
mw.loader.using. Since boot is unconditional and happens ASAP this
happens when the tests are loaded and run.

In the short term this can be avoided by not making the tests depend on
the entire codebase. The long term solution is laid out in T160406.

Supporting changes:
* Bundle assets with webpack@2.4.1.

Baha 9a94300858 Log events to statsv for monitoring PagePreviews performance
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.

Baha 5d4cc8d15a Allow bucketing anons
* Logged in users bypass bucketing. They keep working as before.
* When Page Previews is configured as a beta feature, logged out users
  won't see the feature.
* If an anonymous user has enabled/disabled the feature using
  the settings cog then they will see or not see the feature
  depending on the value of their setting.
* The other anonymous users are bucketed. By default 90% of these
  users see the feature, the other 10% don't. These numbers can be
  controlled by the config variable `wgPopupsAnonsEnabledSamplingRate`.

Sam Smith 61b4e70dea tests: Actually run QUnit tests
I225019b8 introduced a regression where empty Resource Loader modules,
i.e. modules without any scripts, were being added in the
ResourceLoaderTestModules handler because the base directory wasn't
being calculated properly.
