Installing splits into ASECs!

Sessions can now zero-copy data directly into pre-allocated ASEC
containers.  Then at commit time, we compute the total size of the
final app, including any inherited APKs and unpacked libraries, and
resize the container in one step.

This supports both brand new ASEC installs and inheriting from
existing ASEC installs.  To keep things simple, it currently requires
copying any inherited ASEC contents, but this could be optimized in
the future.

Expose new vold resize command, and allow read-write mounting of ASEC
containers.  Move native library extraction into the installer flow,
since it needs to happen before ASEC is sealed.  Move multiArch flag
into NativeLibraryHelper, instead of making everyone pass it
around.  Migrate size calculation to shared location.

Separate "other" package name in public API, provide a path to a
storage device when relevant, and add more docs.
