[1/3][WIP] Base: Squashed commits for 4.4 active display

Add active display to ChameleonOS [1/2]

This is the ChameleonOS implementation of the active
display feature, similar to that found on the Moto X.

When enabled the screen will turn on and display the
incoming notification.  The user can then open the app
for the notification, dismiss the notification or unlock
their device normally.

Additional notifications, if any exist, will be displayed
below the ring notification and can be viewed by touching
the notification icon.  The user can simply slide their
finger across these other notification to quickly view
them.  The last one touched will remain in the ring and
the user can then perform any of the actions listed above.

PS2-PS12:
All the changes that brought us to this current implementation.

Delay hiding systemui by 100ms
When disabling the keyguard, the systemui visibility is
changed and can occur after we hide it so delaying this
a bit resolves that issue.

Active display: make sure mNotificaiton is set correctly

Change-Id: I4831d6864b509e62b449c25619c59f5d6760ec47

Active display: Enable proximity sensor only when screen is off

This should ease people worried about cpu usage of the proximity
sensor while the screen is on.  The sensor listener will only be
registered when the screen goes off, and both active display and
pocket mode are enabled.  Once the screen turns on this listener
will be unregistered so no further updates are received when the
sensor values change.

Active display: Use a default notificaiton icon.

In case there is an exception when trying to load the
notification icon we will use a default one.

Change-Id: I4087ef3e407cf976f7bfb2bb89f850641101bc73

Active display: Only fetch next notification if mNotification is null.

Change-Id: Ife8511d4a4b8c448bc7aa8997a250068bec5fae7

Active display: Don't show active display if call state is not idle.

This will prevent active display from displaying when a call is
coming in and let the call screen show up instead of active display.

Change-Id: I2cb79e097ae24dc6ad6c8a33be88eb19f7d8d235

Active display: Allow apps to be excluded from being displayed [1/2]

This has been a highly requested feature so I guess it's about time
we implement it :).
