add a call to prepareToPlay to HTMLMediaElement::load. prepareToPlay tells the media engine to begin buffering data, so it should not be called if media loading requires a user gesture and load() was not called from one.

Hi, Eric, this change breaks all the youtube embeds on android. For example:
http://apiblog.youtube.com/2010/07/new-way-to-embed-youtube-videos.html
. And the actual submitted patch is not identical to the proposed patch. I am wondering whether we can either: 1. remove the exception throwing behavior? If an exception is thrown, no video control and no poster will be shown in chrome. And user will see a black square in the middle of a page. Or 2. Use the proposed patch, so that we have the RequireUserGestureForLoadRestriction flag.

We should remove the exception because load() is no longer spec'd to throw.
