Checkin apps use /data/misc_ce/<id>/checkin to backup the checkin
metadata. So users won't lose the checkin tokens when they clear
the app's storage.
One example is when GMScore is used for checkin, users may clear
GMScore data via "settings". If the device accidentally loses the
token without backup, it won't be able to checkin again until
factory reset.
The contents in checkin dir will be cleaned up when a user is removed
from the device. We also plan to add Gmscore test to ensure the dir
is cleaned up at checkin time, thus prevent other Gmscore modules
from using this storage by mistake.

Remove some allow rules for odsign, since it no longer directly
modifies CompOs files. Instead allow it to run compos_verify_key in
its own domain.
Grant compos_verify_key what it needs to access the CompOs files and
start up the VM.
Currently we directly connect to the CompOs VM; that will change once
some in-flight CLs have landed.
As part of this I moved the virtualizationservice_use macro to
te_macros so I can use it here. I also expanded it to include
additional grants needed by any VM client that were previously done
for individual domains (and then deleted those rules as now
redundant).
I also removed the grant of VM access to all apps; instead we allow it
for untrusted apps, on userdebug or eng builds only. (Temporarily at
least.)
Bug: 193603140
Test: Manual - odsign successfully runs the VM at boot when needed.

The test for the services has been running with selinux disabled. To
turn selinux on, required rules are allowed.
Below is the summary of the added rules.
* crosvm can read the composite disk files and other files (APKs,
APEXes) that serve as backing store of the composite disks.
* virtualizationservice has access to several binder services
- permission_service: to check Android permission
- apexd: to get apex files list (this will be removed eventually)
* Both have read access to shell_data_file (/data/local/tmp/...) for
testing purpose. This is not allowed for the user build.
* virtualizationservice has access to the pseudo terminal opened by adbd
so that it can write output to the terminal when the 'vm' tool is
invoked in shell.

Allow the MediaProvider app to write the system property
fuse.passthrough.enabled in case FUSE passthrough is enabled.
The need for this additional system property is due to the ScopedStorage
CTS tests that are assuming FUSE passtrhough is always on for devices
supporting it, but there may be some cases (e.g., GSI mixed builds)
where this is not possible true and the feature is disabled at runtime,
thus causing the tests to fail.
This additional system property is only set when FUSE passthrough is
actually being used by the system.

untrusted apps were already granted this policy and we now extend it
to all apps. This allows FileManager apps with the
MANAGE_EXTERNAL_STORAGE permisssion to access USB OTG volumes mounted
on /mnt/media_rw/<vol>.
This permission access in the framework is implemented by granting
those apps the external_storage gid. And at the same time USB volumes
will be mounted on /mnt/media_rw/<vol> with the external_storage gid.
There is no concern of interferring with FUSE on USB volumes because
they are not FUSE mounted.
For sdcards (non-USB) volumes mounted on /mnt/media_rw/<vol>, those
volumes are mounted with the media_rw gid, so even though they are
FUSE mounted on /storage/<vol>, arbitrary apps cannot access the
/mnt/media_rw path since only the FUSE daemon is granted the media_rw
gid.

odrefresh is the process responsible for checking and creating ART
compilation artifacts that live in the ART APEX data
directory (/data/misc/apexdata/com.android.art).
There are two types of change here:
1) enabling odrefresh to run dex2oat and write updated boot class path
and system server AOT artifacts into the ART APEX data directory.
2) enabling the zygote and assorted diagnostic tools to use the
updated AOT artifacts.
odrefresh uses two file contexts: apex_art_data_file and
apex_art_staging_data_file. When odrefresh invokes dex2oat, the
generated files have the apex_art_staging_data_file label (which allows
writing). odrefresh then moves these files from the staging area to
their installation area and gives them the apex_art_data_file label.
