Support for triggering the lockscreen while the screen is on: 



Add new ALLOW_LOCK_WHILE_SCREEN_ON window manager flag, which when set
causes the window manager to put up the lockscreen after the
normal screen timeout has elapsed.

Add plumbing to pass PowerManager.userActivity() to the window manager policy.
