Like dwelling and abandoning, clicking on a preview is the same as
clicking on a link.
This fixes scenario 3 from T159490.

For now, mirror the interaction modelling in the preview reducer in the
eventLogging reducer to handle the user either:
* Repeatedly dwelling on and abandoning a link.
* (Repeatedly) moving their mouse between the link and the preview.
This fixes scenarios 1, 2, 5, and the general issue from T159490.

Step 1 of T161284. Given that the median API response time (as measured
by the client) is ~115 ms [0] and the API response is artificially
delayed so that the preview starts fading in at 500 ms, we can increase
the API request delay to 150 ms without affecting the current UX while
decreasing the number of incidental HTTP requests triggered by the user
glancing their mouse over a link to another page.

When EventLogging is unavailable do not initialise the EL-related code
or try to send any events.
When EL is enabled for a brand new user we request an additional module
during boot causing an additional HTTP request. Page Previews continues
to boot normally regardless of whether the request fails.
This approach doesn't impact boot or first paint time. Once the module
is loaded once it should be cached locally, subject to the
ResourceLoader's policy. Moreover, the RL will not attempt to load the
module twice so this doesn't impact the performance of other modules.

I19e67ae4 hide the overflowing parts of the SVG image element in IE9-11
for a number of cases but not all of them, e.g. see T139297#3089714.
Moving the overflow: hidden property to the SVG element fixes the above
case and is clearer.
Tested in IE9-11 on Windows 7, and Chrome (56.0.2924.87) on macOS Sierra
(10.12.3).

IE doesn't appear to update/redraw the SVG image element when Setting
its clip-path attribute to '', not removing it. This is problematic as
the attribute is always set to a default value (in the createThumbnail
function) before the preview is laid out.

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.

... thumbnails.
A good example of the difference in behaviour of the PageImages API is
here <T156800#3087507>. The API defers to File#transform, which scales
the largest dimension of an image, not always the width, e.g. if an
image is 1000px x 2000px and the request is for a thumbnail "of 1800px",
then the thumbnail will be 900px x 1800px.

If the image isn't an SVG then it shouldn't be scaled past its original
dimensions. Handle the case where the requested thumbnail can't be
generated on the server as the original is too small ( < 320px,
currently [0]) in the same way.
Moreover, if the image happens to have the exact dimensions that we're
requesting (300px or 600px wide, currently [1]), then use the original
image to avoid unnecessary work/pressure on caches.
Supporting changes:
* Update the SVG_RESTBASE_RESPONSE fixture to use the extension returned
by RESTBase (and the PageImages extension) for the thumbnail:
.svg.png.

Instead of importing the modules from sources (which you should do if
you properly define NODE_ENV and use uglifyjs from webpack) import the
already compiled files on the npm packages.
This results in 5kb less on the compiled bundle.

Following on from I19e67ae4, IE9-11's treatment of SVG elements that
overflow their containers means that the truncating pseudo-element and
the settings cog is occluded in a portrait-mode preview.
"Pad" the extract horizontally using a margin to force the SVG element
into the correct position.

The same file is on preview/model.js which is the one actually used by
the application. For some reason the file is a duplicate of model.js,
and it is the file that is required on its QUnit tests.
This patch removes it and points the unit tests to the correct file,
preview/model.js
It was also required by popups.js which was removed in the previous
commit.

Now that most unit tests are run in node with common.js for loading
sources there is no reason to keep global variables around exposing all
the sources.
Only exception is the only qunit integration test processLinks.test.js
which still consumes mw.popups.processLinks, which is the only global
variable remaining in the codebase.
Changes:
* Remove references to mw.popups in code comments and reference the JS
file instead
* Remove popups.js which exposes all common.js modules as global
variables
* Export mw.popups.processLinks in processLinks.js for testing in
processLinks.test.js
