[2/3] mediaeditor: Allow custom DOMX source instead of Google DOMX default

Part 2 of 3 patches: To allow omap4 devices to use custom "domx" source
via a new BoardConfig.mk item:
TI_CUSTOM_DOMX_PATH := device/<manufacturer>/<device-name>/domx

This setting provides for 3 changes during the build:
1. In hardware/ti/omap4xxx this settings stops standard Google domx
source from being built and changes the domx reference for tiutils.
2. In frameworks/base it changes the default openmax references for
frameworks/base/media/jni/mediaeditor/Android.mk to the new location
3. In frameworks/av changes the openmax references in 5 places, and adds
new includes in ACodec.cpp, CameraSource.cpp and OMXCodec.cpp

This commit is based on cherry-pick from omapzoom (with a more descriptive
BoardConfig setting name):

Turn off carrier provisioning by default

Whether or not to use carrier provisioning is a setting hidden to the
end user that is currently not set. Unfortunately, on some carriers that
may result in it being set to yes, or effectively set to yes, without
other accompanying changes that must occur, such as setting a tethering
apn and possibly having a carrier provisioning app, resulting in hitting
a paywall when a tethering plan exists, or, worse having nothing happen
at all when you try to tether since the data doesn't have an apn set.

SystemUI: Navigation Bar: Rotate the search light in landscape

The current search light icon is an arrow pointing upwards, so
while in portrait it points to the direction to be swiped to access
Google Now (and the customizable shortcuts), in landscape it points
upward as well which looks out of place, and swiping upwards reveals
that you have to swipe towards the left to access those targets.
Rotate it by 270 degrees to make it point towards the right direction
(i.e. Towards the lockscreen widgets)
