Source/WebCore:

There is a requirement to have HTML5 video automatically enter
fullscreen when a video starts playing (PR131774). This change
implements this feature, with restrictions. The main restriction
is adherence to WebKit's philosophy of only entering fullscreen
due to a user gesture. This is important in order to avoid
pop-up advertisements and other unwanted fullscreen content.
One consequence of this is that video elements with the autoplay
attribute will not automatically enter fullscreen.

Other caveats:
- This feature applies only to "small screen" devices where
automatically going fullscreen makes more sense.
- Fullscreen will only be entered automatically when the
video is played from the beginning (current time is zero).
It is assumed that if the user is resuming play from a paused
state and is not in fullscreen mode, then they exited fullscreen
mode intentionally.

LayoutTests:

Test that fullscreen is entered automatically when play is
pressed (PR131774). This test applies to handheld (small screen)
devices only, not tablets. The html code for this test was based
on video-controls-fullscreen-volume.html and modified.
