SystemUI: tablet statusbar improvments

1) move clock to the right and adjust padding
2) use a config value for default boolean of whether
   to hide signal bars (to avoid WiFi icon cut off).
   Requires overriding of config_hideSignalBars
   from false to true

DevicePolicy: Fix lockNow() failing to turn off screen

A fix introduced in 93c518e4f8abd98f87cda1712b30a5a86cfa60dd
causes lockNow() to sometimes (most of the time) fail to turn
off the screen. The screen will turn off, but then immediately turn
on showing the lock screen.

This is caused by getWindowManager().lockNow() call which calls the
method to lock the screen, which the PowerManager service also
call in parallel, leading to a race condition.

The fix is to only call getWindowManager().lockNow() if the screen
is not on.

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/.

frameworks/base: enable meta mode for 7x27a video encoder

msm7627a family of chipsets supports only one input frame at
one time. camera expects the input frame to be released before
sending another frame. so send one input buffer and available
output bufefrs to video encoder component. release the input
buffer to camera (to get another frame) after receiving input
frame done callback from video encoder component.

libhwui: Delete display list objects and resources on the UI thread

Bug #6073717
Bug #6065504
Bug #6026515
Bug #5971725

Prior to this change, the destructor of DisplayList would always run
on the finalizer thread. This could cause a race condition if the UI
thread was busy rendering display lists at the same time leading to
various random native crashes.
