Original change's description:
> arc: Add wake lock based logic to re-suspend after dark resume
> 
> This change adds functionality to support lock screen notifications for
> Android. The wake lock module now listens to dark resume notifications
> from the power manager. It -
> 
> 1. Starts a timer to check for partial wake locks acquired by Android.
> 
> 2. After the timer in 1 expires, if no partial wake lock is acquired the
> power manager is requested to re-suspend the system. If a partial wake
> lock is acquired, then another hard timeout timer is set and also an
> observer to wake lock release is set.
> 
> 3. If wake lock is released, the system is re-suspended immediately.
> 
> 4. If a wake lock is still acquired but the hard timeout expires then
> the system is re-suspended immediately.
> 
> 5. If the system transitions to a full resume all dark resume related
> state and timers are cleared.
> 
> BUG=chromium:898297
> TEST=Unit tests and end to end test with Android applications.
