Reduce latency from doze to screen on.
Don't wait for the brightness ramp to complete before reporting
display ready. Keep track of whether we have any unfinished
brightness changes and take care to grab a wakelock to ensure
they are eventually applied.
Ideally we would rewrite the whole state machine to more carefully
coordinate screen state and brightness changes but that's too
risky for now.
The pixel fairies are having a bad day.

Add trace tag for power management.
Instrumented the basic power manager state transitions,
calling into the Power HAL, setting the display power mode,
and setting the backlight.

Allow dreams to control screen state and brightness.
Added setDozeScreenState() and setDozeScreenBrightness() methods to
DreamService. The values specified here only take effect once
startDozing is called and can be changed while dozing.
This required some significant rework of the display power controller
but the result seems quite nice and better represents the policy
we want to apply.
Changed the test dream a little bit to make it flash the screen
every minute using the new functions.

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.

Move display power controller to display manager service. (DO NOT MERGE)
This refactoring is in preparation for enabling the display manager
to have more control over the blanking state of individual displays.
There are no functional changes. Some bits will be cleaned up in
a subsequent patch.
