Plumb display power state through display manager.

Declare a new method, Display.getState() to retrieve the actual
power state of a display.

Improved documentation for Intent.ACTION_SCREEN_ON and
Intent.ACTION_SCREEN_OFF to clarify what they really mean in
terms of the interactive state of the device.

Deprecated PowerManager.isScreenOn() and replaced it with
PowerManager.isInteractive() with a more suggestive name and
better documentation.

Redirect display power state changes to go through the display
manager first and only then head over to the power manager for
legacy compatibility.

Eliminated the bright here and woke here policy flags since they
were unused.  Simplified the input dispatch policy somewhat.

Ensure that screen wake locks are respected up until the point
when dozing really begins.

Fixed a regression in DreamService where onDreamingStarted
might be called before onWindowAttached.
