System services detect and register app CPU ABIs
This patch uses the NativeLibraryHelper class to
match native libraries in an .apk package with
those listed in 'ro.cpu.abilist' property.
The result is stored in packages.xml and the
ApplicationInfo class.
This information will be used by the ActivityManager
to decide which zygote to use to launch the given
app.
