<h3>Log Message</h3>
<pre>Media controls don't appear when pausing a small autoplaying video
https://bugs.webkit.org/show_bug.cgi?id=159972
<rdar://problem/27180657>
Reviewed by Beth Dakin.
Source/WebCore:
When pausing an autoplaying video, remove behavior restrictions for the
initial user gesture and show media controls.
New WebKit API test. See VideoControlsManagerSingleSmallAutoplayingVideo.

(WebCore::HTMLMediaElement::pause):
Tools:
Adds a new test that verifies media controls show up when pausing a small autoplayed video. Also adds mechanisms
for simulating basic user interaction in VideoControlsManager.
