Adds android:targetName to the overlay manifest attributes and PackageParser reads the name into PackageInfo. Specifying android:targetName on an overlay allows the overlay to be associated with a particular set of overlayable resources. The overlay can only override the values of the resources defined within the target overlayable element.
