With this change, vold exposes an API that may be used to bind key
storage encryption keys to a given seed value. The seed value passed to
vold must be consistent across reboots, or key storage keys will not be
derived consistently. The seed is expected to be set very early in boot,
prior to the use of any key storage encryption keys.
This feature is intended to be used for embedded applications such as
in autos, where the seed may be provided by some other component of the
system. In such systems, there is a default user that is automatically
signed in without a PIN or other credentials. By binding the file
encryption to a platform-provided seed, the default user's data gains
additional protection against removal of the Android embedded device
from the integrated system.
Bug: 157501579
Test: Set seed at startup via init.rc. Seed changes fail as expected.

This reverts commit a71323ec0e.

This reverts commit 8ed81fd9ca.
Reason for revert: Let me try one last time more carefully. According to https://googleplex-android-review.git.corp.google.com/q/%2522customize+stubvolume%2522 - this CL will flow to aosp branches (without vendor images) and 2 branches with vendor images. I have submitted the vendor CL for both branches now (ag/13366009 and ag/13371672). This should not break anything now.

This new method will be used in new sm command.
Tests can use this so data and obb dirs are unmounted, and won't
be killed when volume is unmounted.

This directory is used as a root for external storage on adopted storage
devices. It needs to be writable by processes holding the AID_MEDIA_RW
GID permission; in particular, it should be writable by the FUSE daemon.
On devices with sdcardfs, this was ensured automatically, because
sdcardfs presented a view of this directory that was writable, that we
could use for the FUSE daemon. But on devices without sdcardfs, the FUSE
daemon sees the raw filesystem and its permissions. This also means that
files created by the FUSE daemon will have their uid/gid set to the uid
of the FUSE daemon; to ensure these files stay writable to other system
applications that have AID_MEDIA_RW, use a default ACL to make sure the
gid stays AID_MEDIA_RW.
In particular, this fixes an issue with app cloning, where we want the
FUSE daemon of user 0 to be able to access the files of the app clone
user, and vice versa.

This is already on for all Pixel devices with no problems observed.
If this causes issues with a specific device (e.g. vendor apps being
unable to access their data) it can be temporarily disabled by adding
PRODUCT_PROPERTY_OVERRIDES += ro.vold.level_from_user=0
to the device.mk file. Please file a bug if that happens.

(cherry picked from commit 763393644a)
As storage is not mounted in system server, we use vold
to check if storage app data and obb directories exist instead.
We add a method in vold so it only creates app data and obb dirs
if dirs do not exist to speed up app starting time.
Bug: 160336374
Test: Data and obb directories are created when a new app is started
