During package scan, only the primary user data directories were
checked. If the secondary user didn't have an application directory, it
would happily ignore it. The app would then crash upon startup.

Amazingly, some apps still don't use the nativeLibraryPath. So add a lib
symlink for non-primary users to fix that.
Also, there was an error when the symlink existed that it would give up.
This shouldn't really happen, but in that case, just remove it and
create a new one to be safe.
Also, move the downgrade code to the appropriate place. This downgrade
case triggered the above symlink existing bug.

Previous commit attempted to move setfilecon above chown, but mistakenly
squashed libdir and pkgdir setfilcon into one incorrect setfilecon.

Count the lib symlink against the app's code size. Also be sure to
look at the new separate lib path for apps, and tweak the size
counting to also count the size of directory entries.

Now we correctly iterate through the different user cache dirs.
Also update documentation to describe the new cache pruning behavior,
and deprecate the file modes for making files world readable/writable
which we really don't want people using any more.

unlinklib is no longer necessary since libraries are now either stored
in an ASEC container or in /data/app-lib
Replace lib directory with a symlink to the /data/app-lib directory even
if it's a dangling link. That way developers don't name something "lib"
in their directory which gets blown away during an update.

Make installd run with fewer privileges. This will help make
exploitation of installd based vulnerabilities more difficult
to perform.
installd now runs with the following privileges:
* CAP_DAC_OVERRIDE
* CAP_CHOWN
These two capabilities are needed to add and remove files
from application's home directories.
* CAP_SETUID
* CAP_SETGID
These permissions are needed to further drop privileges when
running dexopt as the application UID.
"installd" no longer runs with full root privileges. It cannot,
for example, mount and unmount filesystems, install modules,
perform direct I/O, etc.

Emulated external storage always has multi-user support using paths
like "/data/media/<user_id>". Creates and destroys these paths along
with user data. Uses new ensure_dir() to create directories while
always ensuring permissions.
Add external storage mount mode to zygote, supporting both single-
and multi-user devices. For example, devices with physical SD cards
are treated as single-user. Begin migrating to mount mode instead
of relying on sdcard_r GID to enforce READ_EXTERNAL_STORAGE.

This rewrites installd's code for deleting cache files to be better:
- Isn't really stupid about just deleting directories in the order
they are found on the filesytem; now collects all cache files and
sorts them by mod time to determine which to delete.
- Also deletes cache files in /data/media and for all users.
This also tweaks DeviceStorageMonitor to be a little smarter about
deciding when to flush cache files, having upper and lower limits
that it allows memory to get down to and then flash files to reach
the higher free storage limit. This should reduce the amount that
we perform flushing when starting to reach the storage limit.
Finally add a new pm command to force a cache flush.

...mismatched uid: X on disk, Y in settings" errors on Froyo and Gingerbread
Deal more gracefully with the uid changing in three ways:
1. If the uid on disk has become root, then have installd change it to
the application's uid. This is to correct a potential case where
installd was interrupted while linking or unlinking the libs dir,
during which it temporarily changes the owner of the dir to root
so that a malicious app can not get in its way. So if the uid on
disk has become root, we assume we can safely just change it back
to the correct uid.
2. When scaning packages at boot, use the same "delete and rebuild data
directory" code for third party applications as we have for system
applications. This allows us to at least end up in a state where the
app will run, even if its data is lost.
3. But we really don't want to get in to case 2, so if an application
update is being installed and we find that the uid we now have for
the app is different than the one on disk, fail the update. This will
protect against for example a developer changing the sharedUserId of
their app and getting into this bad state.
