frameworks_base/libs/androidfw/tests/LoadedArsc_test.cpp
Ryan Mitchell 8a891d86ab Allow for RRO internal referencing 
This change allows RROs to reference their own internal resources as
expected.

Overlays are loaded as shared libraries so they can have their own
resource id space that does not conflict with the resource id space of
the target or other overlays.

References to overlay resources that override target resources now
appear as references to the target resources.

Overlay values that are inlined into the xml file specified using
android:overlayResources are now able to be used at runtime.

See go/rro-references for more information.
