Reimplement ZipFileRO in terms of libziparchive.
This lets us share zip archive processing code with both
the runtime (Art, dalvik) and critical java code
(StrictJarFile).
This change also moves several utility methods to ZipUtils
and dedups code across several zip inflation methods.
One of the side effects of this change is that several
processing loops are now O(n) instead of O(n^2).
