Plumb the referrer throughout the OpenURL APIs.

http://code.google.com/p/chromium/issues/detail?id=3224

Caveats:
* Did not update TabNavigation yet. Hence session restore will continue to load the tabs with empty referrer.
* Did not plumb referrer into incognito url open. (Not sure what the right thing to do is here with respect to privacy vs compatibility.)
* Did not plumb referrer throughout the automation controller. No functional impact here, but it makes the code inconsistent with the non-automation version.
