<h3>Log Message</h3>
<pre>[mediacontrols] Test the ordering of elements in the controls panel
https://bugs.webkit.org/show_bug.cgi?id=148804
&lt;rdar://problem/22579232&gt;

Reviewed by Eric Carlson.

Source/WebCore:

Add information about various controls elements to the status object.

Test: media/controls/elementOrder.html

* Modules/mediacontrols/mediaControlsApple.js:

LayoutTests:

Add a new test that checks the visual order of the buttons and
elements in the controls panel. This is helpful because they
are not necessarily in that order within the DOM.

I also added caching of the current state to the testing helper,
to save generating the JSON status multiple times in subsequent
calls.

* media/controls/elementOrder.html: New test.
* media/controls/elementOrder-expected.txt: New results.
* media/controls/controls-test-helpers.js:
(ControlsTest):
(ControlsTest.prototype.get currentState): Added caching.
(ControlsTest.prototype.stateForControlsElement):
(ControlsTest.prototype.isGreaterThan): New test helper.</pre>
