75e20dda2b
This change defines two new chunks for encoding overlayable information. RES_TABLE_OVERLAYABLE_POLICY_TYPE contains flags that represent restrictions enforced on overlays that try to overlay a specific set of resource ids. The chunk header is followed by ResTable_ref for each id that belongs to the policy type. A policy chunk will be created for every unique combination of policies that are defined in overlayable declarations. RES_TABLE_OVERLAYABLE_TYPE holds policy blocks. Since <overlayable> does not currently have any attributes, only one overlayable block is encoded in an APK. This change also removes the SPEC_OVERLAYABLE flag because the runtime does not use the flag, and the overlayable chunk encoding renders it obsolete.
