The timing variable is a private closure variable containing an object
that tracks the timestamps of different events in the current cycle. The
duration variable is the result of using that information to compute the
difference between the current timestamp and the relevant anchor
timestamp. For the '_timing' property in the EventLogging data, duration
is the correct value, not timing.
(This is confusing and we should probably rename the timing variable.)

The schema itself is being renamed, many of the field names are
different, and two new fields were added (page_token and session_token).

Respect the config var exported by WikimediaEvents that, if set to true,
forces oversampling. When oversampling, all events are logged even if
they would have been sampled out. The isOversample property is set to
true if the event was oversampled and would not otherwise have been
logged.

Instead of hard-coding the 6.25% sampling rate, allow it to be
controlled by the config variable in the WikimediaEvents extension
(which also defines the RL module for the Edit schema).
Also use sampling code from EventLogging so we can configure the
sampling rate as a number, rather than using a hex-digit based strategy.

Rather than computing all the data then throwing it away 93.75% of the
time. Also use .charAt() for consistency with WikiEditor.

ve.track tries to guess the platform, but it needs a loaded Target to do so,
and init happens before that.
Also, log a warning when this happens, in case it comes up again.

In Schema:Edit, all action timing durations (ready, loaded, saveAttempt etc.)
are defined as "time since the editor was initialised", which is internally
stored as the timestamp for the "init" action.
The 'init' action itself does not have a timing duratation, but the Edit schema
has a special case for it, definining it as "time since the page was loaded".
In actually, it isn't actually implemented as "time since the page loaded",
and I suspect that as such, this value is probably not used by EventLogging
consumers of the Edit schema. Or, it might be used, but doesn't represent
what the consumers think it does.
Presently, it uses the init time now() - mediaWikiLoadStart, which basically
means the time between the random point at which MediaWiki core JavaScript
finished executing which is quite variable in practice due to the race between
<script async> and browssing parsing/rendering of HTML. That is by design,
and is also why mediaWikiLoadStart is undocumented and internal, and actually
in the process of being removed.
After many iterations on this patch to try and approximate an alternative to
this undocumented variable, I came up with an alternative approach with DLynch
at the Hackathon, which is to simply not record this one timing value, but
preserve the behaviour of all the other timing values exactly as-is.
That is, keep the behaviour of storing `now()` as "init" when the editor
activates, and keep the behaviour of substracting "init" from all other action
times, but only don't report "init" itself to EventLogging (given its value
would be 0, which isn't useful).

If70ff601 didn't really fix anything. The only reason you'd want this data is
to distinguish between mobile and desktop data, but it just set the value to
the desktop version always...

We're currently rewriting "mwtiming.performance.system.domLoad" to
"timing.ve.undefined.performance.system.domLoad". The "undefined" comes from
the missing targetName property on the event. I'm not sure why it is missing,
but having it default to 'mwTarget' will Do the Right Thing™.

Still misses some preinit aborts because we need to figure out
a way to attach the unload handler early enough to catch these.

timeStamp was used in two places, but we only had back-compat
code in one, so the other ended up using NaN.
Bonus: make jshint happy with the indentation of the $.extend() call.

* Use the event's timeStamp rather than the current time in the event
subscriber.
* Instead of using ve.trackSubscribeAll() and then branching on the topic
prefix, just use ve.trackSubscribe( prefix, ... ) to bind prefix-specific
handlers.
* Round timing measurements after performing arithmetic, and use Math#round
rather than Math#floor.
* Rename 'getDefaultTiming' to 'computeDuration'.

This API doesn't have the ability to track any other data
in addition to a name and a duration in milliseconds, so
we add the target name ('mwTarget' or 'mobile') to the
event name and discard all other data.

Aside from the confusion and differences between substr() and
substring() and IE8 bugs with substr(), substr() was removed from
the spec as of ECMAScript 5. It's been standardised in the
optional Annex B section of ES5.

Move ve.track() subscriber to its own file, and have it
route mwtiming.* events (for TimingData) and mwedit.* events
(for Edit schema) differently. Most of the data population
lives in the subscriber, so actual ve.track() calls are
pretty lightweight.
Existing ve.track() calls with timing data were kept with
their names intact for backwards compatibility, but
we may eventually want to throw them out and start from scratch.
ve.init.mw.ViewPageTarget.init.js:
* Remove old track subscriber
* Track init and ready events
* Remove old ve.track( 'Edit', ... ) crap that didn't work
ve.init.mw.ViewPageTarget.js:
* Fire the saveWorkflowBegin event before the save dialog
loads rather than after
* Remove unnecessary this.events.trackSaveError() calls:
TargetEvents already listens to these events itself
* Remove badtoken handler because all it was was an
unnecessary trackSaveError() call
* Add abort tracking
** Pass trackMechanism through deactivate() and cancel()
ve.init.mw.Target.js:
* Add static.integrationType to populate the 'integration'
field in the schema
ve.init.mw.TargetEvents.js:
* Simplify onSaveError* methods away into connect bindings
* Map track topics to mwtiming.* so they can be routed separately
* Track save-related mwedit.* events
