Sam Smith dcf8532cdf Hygiene: Group instrumentation modules
Following on from I4f653bba, since the schema and statsvInstrumentation
modules are similar, let's group/rename them:

  schema -> instrumentation/eventLogging
  statsvInstrumentation -> instrumentation/statsv

Sam Smith 67eb3b1dcf i13n: Log EL events with mw.track
Currently, the mw.eventLog.Schema class samples per pageview. However,
we expect that if a user is bucketed for a session, then all
EventLogging events logged during that session are in the sample.

Moreover, loading the class in the way that we did - asynchronously,
using mw.loader#using - introduced an issue where the eventLogging
change listener would subscribe in the next tick of the JavaScript VM's
event loop and miss the "pageLoaded" event being queued (see T167273).

Changes:
* Make the schema module follow the form of the statsvInstrumentation
  module, i.e. make it expose the #isEnabled method, and add the
  associated getEventLoggingTracker function.
* Update the eventLogging change listener accept the tracker returned by
  getEventLoggingTracker.
* Update/fix related JSDoc documentation.

joakin 98d9415361 Hygiene: Rename builder vars on require preview/model
preview/model is just a module/namespace object, not a builder class or
similar.

This patch changes a couple of imports to reference some of the exposed
functions of the preview/model where required.

In a shiny future, this pattern would be:

    const { createModel, createNullModel } =
      require( '../preview/model' )

joakin 010a4d91a6 Hygiene: Simplify gateways
gateway/*/rest were copies of gateway/restProvider just passing
a different provider. Docs were the same, they were untested, and
looking at them they seemed like unnecessary abstraction.

This patch removes the plain vs html structure, and separates gateways
like before, by endpoint.

There is a light utility in gateway/restFormatters.js that adapts the
call from the rest gateway to use formatters.js functions. It needs
testing, that I'll add in the next patch.

The flow for creating a gateway ends up as follows:

1. index.js calls gateway/index#createGateway( mw.config )
2. createGateway chooses based on wgPopupsGateway and invokes
  * mediawiki.js#createMediaWikiApiGateway or
  * rest.js#createRESTBaseGateway w/ restFormatters.js#parsePlainTextResponse or
  * rest.js#createRESTBaseGateway w/ restFormatters.js#parseHTMLResponse

Changes:
* Removed src/gateway/{plain,html}/rest.js
  * Extracted formatter functions to src/gateway/restFormatters.js
* src/gateway/plain/mediawiki.js -> src/gateway/mediawiki.js
         * tests/node-qunit/gateway/plain/mediawiki.test.js ->
           tests/node-qunit/gateway/mediawiki.test.js
* gateway/restProvider{,.test}.js -> gateway/rest{,.test}.js
* Change gateway/index.js#createGateway to properly call the rest
  gateways with the rest formatters

Refactor existing Restbase gateway and extract shared logic into

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 293d7ebe8d Clear interaction after an event for it is logged in EL
Given that interactions end up with an event logged, there shouldn't be
a reason to keep an interaction active after it's corresponding final
event has been logged. See Tbayer's state graph.

This patch removes the current interaction if an event with that token
is logged, effectively finalizing it and making it impossible for the
token to be reused from the state tree again.

Additional changes:
* Pass the logged event with the action EVENT_LOGGED so that the reducer
  can determine if it needs to do anything else.
* Since the interaction is removed, when undefined, guard against
  actions that use state.interaction freely. (Only allow BOOT,
  LINK_PREVIEW, and EVENT_LOGGED)

Sam Smith 79f3b318d0 Track and discard duplicate enqueued events
The eventLogging change listener is responsible for ensuring that the
internal state of Page Previews matches its external state (that
perceived by the user and UA). It does this by logging events with
ext.eventLog.Schema#log. This makes it the perfect place to track and
discard duplicate events enqueued by the Page Previews codebase observed
in T161769.

Make the change listener track events that it's logged by storing hashes
of the dynamic parts of them in memory. If the eventLogging change
listener sees the same event more than once, then it discards it and
increments a counter in StatsD.

This behaviour should be enabled for a matter of days as we should see
whether the duplicate events are being enqueued by the Page Previews
codebase immediately.

Sam Smith 3d0899c0a0 Remove isLoggingEnabled with Null Object pattern
The statsv change listener depended on both the analytics tracking
function and whether it should log metrics to StatsD. We can simplify
the behaviour of the change listener by passing in a function which
doesn't log metrics to StatsD if such logging is disabled.

The change listener is now more isolated from other components.
Moreover, sharing the analytics tracking function with other components
is simpler as there's no repeated code.

Sam Smith 7f91068ecf Don't show preview if user has abandoned link
If the user dwells on a link for long enough, then the gateway makes a
request, which is allowed to complete regardless of whether or not the
response is required.

If the user abandons the link but the request completes before the
abandon completes - currently, ABANDON_END_DELAY is 300 ms - then the
preview will be rendered temporarily.

Fix this by not rendering the preview if the user has started to abandon
the link.

If the user CmdOrCtrl+Clicks on a link, then the link will remain
focussed. If a preview is shown, clicks another element on the page, and
then there'll be no token to include in ABANDON_* with.

Sam Smith 2c171d7f25 reducers: Don't destroy interaction on LINK_CLICK
I09d8776 introduced a bug in the eventLogging reducer where reducing
LINK_CLICK would remove any accumulated interaction state but not close
the interaction.

Update the associated tests so that they correctly test the reduction of
this action.
