Frameworks/SystemUI: Hide expanded dialog when screen is off

Hide the expanded dialog while screen is off. Otherwise it
causes continuous buffer updates to SurfaceTexture
even when SCREEN is turned off and while In-Call causing a
spike in power consumtion. This fix ensures that the
power consumption is kept to a minimum in such a scenario.

Sensor: Add RotationVectorSensor2

Some ICS apps (namely, Google Maps) expects a rotation vector to be
available. Newer devices, this is provided by either Android's
sensor fusion (requires Gyro) or by hardware sensor fusion (MPL).

Older devices will lack this virtual sensor and compass in Google
Maps will not work. To fix this, we can provide our own rotation
vector sensor by converting the values from the orientation sensor.
(They are basically the same information in different formats.)

Thanks to Unhelpful for the help with related math.

Bugfix : Expanded volume overlay

If you switch to the Expanded volume overlay
(Settings > Sound > Volume panel)
from any of the other settings that are not expanded
then the Expanded overlay appears collapsed.

The only way to make it appear expanded is to restart the framework
or
In the Expandable view - expand the volumes - then immediately change.

This patch fixes this and also has a slight improvement in the
case where a user selects the same choice they have already.

Notification light(LED) settings: package mapping

Credit for this code goes to Marko Mihovilic

This commit allows for framework side override of the application
package name set for Notification light led overrides.  This is used
in cases where the user selectable application sends its notifications
via another package.

Specifically:  GTalk (com.google.android.talk) sends notifications via the
Google services framework (com.google.android.gsf).

Patch set 2  - fix derp and whitespace cleanup
Patch set 4  - fixed another derp
Patch set 5  - fixes typo in comment
Patch set 6  - remove Log.d line
Patch set 7  - allow specifying default values in application notification
               overrides

tethering: Tolerate socket exception from ifindex look-up

The code already handles the case of internalNetworkInterface being null,
but this would never happen since it throws an exception if
NetworkInterface.getByName(internalInterface) fails. Catch the exception
and continue processing.

This is needed with some older usb gadget code which don't populate
/sys/class/net/usb0/.

SystemUI: Fix alignment of the Settings icon on tablets

At some point the Settings icon in the notification panel header got
left aligned (next to battery) rather than right-aligned as it was
originally.  This commit fixes moves the icon back to the right where
it belongs.
