Automated Commit: Committing new LKGM version 5535.0.0 for chromeos.

git-svn-id: svn://svn.chromium.org/chrome/trunk/src@252845 0039d316-1c4b-4281-b951-d872f2087c98
Use Display changes for screen orientation changes.

This is the only reliable solution: we get an event from DisplayManager
every time a display change. If that change is a rotation change from
the display we care about, we can act on it. Using sensors or
onConfigurationChange is unreliable.
