Use inode numbers for CE storage, fix sizes.
Certain operations, such as clearing/destroying app data, or just
counting on-disk size, require us to know the CE storage directory
of a particular app. To facilitate these operations, offer a method
to get the inode of a CE directory, and accept that inode number
for later operations.
In previous releases, we started installing apps using a new
directory-based layout, where all app code, unpacked native libraries,
and optimized code is bundled together. So now we only have a single
path to measure for code size.
Start measuring both CE and DE storage data usage for apps, and tweak
the reporting so that empty cache/data directories actually show up
as "0 bytes".
Fix bugs in disk usage counting, since st_blksize has no bearing on
the allocated disk space. Also don't double-count "." and ".."
directories when measuring storage.
