Jeff Sharkey d792118c49 Offer to move both code and data together.
We now move code under /data/app/com.example when a complete move
is requested.  This really only works for new cluster-style installs
that also have native libraries and OAT contained inside.

Teach measuring code about cluster-style installs when measuring
app footprint.  Also offer to measure private data space for all
users.
