Without the directory (this happens on the very first boot),
load_persist_props can't create an initial version of
/data/property/persistent_properties (probably empty). This leads to
persisting all in-memory "persist.*" properties later when a persistent
property is set. This is regression from Android S because persistent
props from, for example, build.prop will be persisted even when there's
no process to explicitly setprop.
Bug: 242264580
Test: launch cuttlefish and verify that there's no props from build.prop

This reverts commit da94c7f650.
Reason for revert: It appears this change slows down boot on normal devices.
Technically, this change is not necessary, but it prevents starting the secondary and having it throw an error in the only run 64 bit zygote config. But it's easier to throw the error than slow down boot up.
Bug: 238971179
Test: Verified that on a 64 with 32 config, the secondary zygote
Test: starts but exits.

In previous releases, these self tests had a secondary purpose
of writing a flag file to save future processes from running
some slow self checks. This is no longer true in T.
However running the tests from early-init has caused issues
on some devices as the kernel's entropy pool is not yet
initialised, causing the process to block for a second or more.

The SELinux type of /data/media has changed from media_rw_data_file to
media_userdir_file, but the recursive restorecon of /data happens too
late when taking an upgrade. Add a restorecon of /data/media to just
above the chattr command which needs the new label to be allowed. This
doesn't "really" matter, since the chattr command is only needed just
after the directory was created anyway, but this fixes a SELinux denial.

Although metadata encryption makes the device encryption policy
redundant, for now it is still being used, and the rule is still that
every top-level directory in /data is encrypted by the device policy
unless there is a specific reason why the directory can't be encrypted.
There are various cases where encryption=None is legimately needed and
is used, but they aren't explained in the code, and the option is prone
to be copy-and-pasted (as was done in https://r.android.com/1932960).
Fix this by explicitly commenting every case where encryption=None is
used, and consolidating the creation of all the user parent directories
into one place. (I left /data/bootanim as-is since it will be changed
to encrypted; see b/232299581.)

Directories should always be encrypted unless there is a specific reason
they can't be. /data/bootanim is unencrypted without a specific reason,
so fix it to be encrypted. It is too late to use encryption=Require.
However, the contents of this directory doesn't need to be preserved on
updates, so we can use encryption=DeleteIfNecessary instead of
encryption=Attempt.

Since apexd.status=ready is system-only property, we need a similar or
equivalent event or property which non-system APEXes can use to define

To prevent bugs, directory creation and encryption should happen
together. /data/user/0 (and its "alias" /data/data) is a per-user
encrypted directory; such directories can only be encrypted by vold.
Therefore, move its creation to vold as well.
Besides closing the uncomfortably-large gap between the creation and
encryption of /data/user/0, this allows removing init's write access to
/data/user and similar directories (SELinux type system_userdir_file) to
prevent any such issues from being reintroduced in the future.
To also allow removing init's write access to /data/media (SELinux type
media_userdir_file), which also contains per-user encrypted directories,
also move the creation and encryption of /data/media/obb to vold.

[1] changed the UID of the virtualizationservice daemon and
/data/misc/virtualizationservice directory to `system`. However, this
can cause a permission denial issue when the directory has stale files
when the device was running a build before [1] and an OTA to [1] (or
above) is attempted. The daemon tries to delete the stale files - which
must have been still labeled as old UID and thus the daemon has no
privileged to delete them.
Fixing this issue by ensuring that the directory is always empty by
init.

Previously, virtualizationservice had its own UID
`virtualizationservice`. As a result, crosvm, which is spawed by
virtualizationservice`, also run as the UID. However, that prevented us
from applying task profiles to the crosvm process because joining a
process to a cgroup requires system UID.
To fix that, virtualizationservice now runs as system UID. As a result,
this directory that virtualizationservice accesses has to change its
owner and group to system.

/dev/kvm and /dev/vhost-vsock are used by crosvm. Previously, it ran as
a custom UID `virtualizationservice`. However, this prevented us from
applying task profiles to the crosvm process because joining a process
to a cgroup requires system UID.
Now, crosvm (and its parent virtualizationservice as well) runs in
system UID. Therefore, the ownership of two device files are also
updated accorgly.
