The eventlogging `isEnabled` function determines when to sample,
this patch removes the `isAnon` conditional so that we can measure
reference reading habits for all users.
Also guards against a non-function navigator.sendBeacon, which was
previously intended but incorrectly tested.

These are annotations for ESLint as described at:
https://eslint.org/docs/user-guide/configuring#specifying-globals
I'm not sure where the `…: false` comes from. I assume it is a mistake
and does not have an effect.
I tried to move these annotations closer to the line they are about in
case there is only one line. And move it to the top when there is more
than one line using the global.

Replace all test assertions for calledOnce / Twice with callCount.
assert.ok( calledOnce / Twice ) only lets the dev know that a test
fails. assert.strictEqual( callCount, EXPECTATION ) starts the debugging
process when it fails since it provides the difference in the failure
output. strictEqual() was deliberately used since it's a saner default
and the codebase already favors === equivalency checks.

No longer needed. We can't turn something off again for people
now they expect it to exist.
Clarified usage instructions of PopupsEventLogging to make sure
it's more scary given the implications

Enforce it with eslint.
Ignore:
* Comment lines with eslint disable directives
* QUnit test lines as they contain long subjects (QUnit.* (only, test,
module, skip, etc)
* Strings, since long strings are used extensively in tests
* Ignore template literals for similar reasons
* Regex literals as they may be too long, but can't be easily
split in several lines
* Long urls
See bug for more general proposal for eslint-wikimedia-config.

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.

Previously, if the browser didn't support the Beacon API, then
instrumentation/eventLogging#isEnabled would bucket the user with a
sampling rate of 0, which is equivalent to returning false. This change
simply does the latter.
Additional changes:
* Update the documented module names of the instrumentation/eventLogging
and statsv modules.

In order to debug the EventLogging instrumentation in production
environments, we want to be able to bucket ourselves at will.
When the debug flag (?debug=true) is passed send all events
for given page view.

Following on from I4f653bba, since the schema and statsvInstrumentation
modules are similar, let's group/rename them:
schema -> instrumentation/eventLogging
statsvInstrumentation -> instrumentation/statsv
