libandroidfw hardening for IncFs

Migrate libandroifw to using incfs::util::map_ptr to prevent processes
from crashing when parsing the resources.arsc, parsing compiled xml,
files, and retrieving resource values.

This change propagates incremental failures to the JNI level where they
are raised as ResourcesNotFoundException.
