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
'on' trigger actions.

automatically.

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.

Delete all files and directories under

Test: Create fake stale dir+file, see them deleted

(cherry picked from commit 34ee0c931c)
[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.

This patch preserves the following parameter values:
* Foreground BFQ weight: 100
* Foreground CFQ group_idle: 0
* Foreground CFQ weight: 1000
* Background BFQ weight: 10
* Background CFQ group_idle: 0
* Background CFQ weight: 200
The foreground BFQ weight in task_profiles.json is the default BFQ
weight. From
https://www.kernel.org/doc/Documentation/block/bfq-iosched.txt:
"weight (namely blkio.bfq.weight or io.bfq-weight): the weight of the
group inside its parent. Available values: 1..10000 (default 100). The
linear mapping between ioprio and weights, described at the beginning
of the tunable section, is still valid, but all weights higher than
IOPRIO_BE_NR*10 are mapped to ioprio 0."

/sys/class/block covers all of dm-[0-9], sd[a-z], mmcblk[0-9].
Use it instead of /sys/devices/virtual/block, which only covers dm
devices.
This allows f2fs tunings to be applied more reliably regardless of
how the userdata partition is set up.
Do note that while everything under /sys/devices/virtual/block are
expected to have correct SELinux labels by AOSP, some under
/sys/class/block are not as it's symlinked to platform-specific paths,
and it is up to the vendors to label them correctly.
Test: Confirm entries under /dev/sys aren't dangling and cp_interval,
gc_urgent_sleep_time, iostat_enable and discard_max_bytes are
all set up properly under FBE, FDE and unencrypted.
