Split gsi_metadata_file into gsi_metadata_file plus
gsi_public_metadata_file, and add gsi_metadata_file_type attribute.
Files that are okay to be publicly readable are labeled with
gsi_public_metadata_file. Right now only files needed to infer the
device fstab belong to this label.
The difference between gsi_metadata_file and gsi_public_metadata_file is
that gsi_public_metadata_file has relaxed neverallow rules, so processes
who wish to read the fstab can add the respective allow rules to their
policy files.
Allow gsid to restorecon on gsi_metadata_file to fix the file context of
gsi_public_metadata_file.
Bug: 181110285
Test: Build pass
Test: Issue a DSU installation then verify no DSU related denials and
files under /metadata/gsi/ are labeled correctly.

We no longer allow apps with mlstrustedsubject access to app_data_file
or privapp_data_file. For compatibility we grant access to all apps on
vendor images for SDK <= 30, whether mlstrustedsubject or not. (The
ones that are not already have access, but that is harmless.)
Additionally we have started adding categories to system_data_file
etc. We treat these older vendor apps as trusted for those types only.
The result is that apps on older vendor images still have all the
access they used to but no new access.
We add a neverallow to prevent the compatibility attribute being
abused.

Define two property_context.
1. vendor_socket_hook_prop - for ro.vendor.redirect_socket_calls. The
property set once in vendor_init context. It's evaluated at process
start time and is cannot change at runtime on a given device. The set
permission is restricted to vendor_init. The read permission is
unrestricted.
2. socket_hook_prop - for net.redirect_socket_calls.hooked. The
property can be changed by System Server at runtime. It's evaluated when
shimmed socket functions is called. The set permission is restricted to
System Server. The read permission is unrestricted.

Due to Factory OTA client install in product partition but it also declare coredomian in
its sepolicy setting. That will let Factory OTA unable to find a property type could write system property.
But now Factory OTA have a restore NFC wake function need to write system property for communicate with bootloader.
So we need to create a new property type in system framework which could allow Factory OTA client to write system property.

The commit 7baf725ea6 broke OMX on O/O-MR1(/P?) vendors.
Previous to this commit, all OMX codecs had to use "mediacodec" type,
after this commit, omx codecs just had to get hal_omx_server attribute.
This commit left to the vendor the charge of adding "hal_omx_server"
attribute to mediacodec.
However this can't work on non-Q vendors.
On P vendor, versioned_plat_pub contains the appdomain <=> mediacodec
allows, so OMX isn't technically broken on those devices.
But to ensure it won't break in the future, mark 28's mediacodec as
hal_omx_server as well
This fixes broken OMX decoding on O/O-MR1 vendors, failing with the
following denial:

apexd stops itself when it finds that it is running on a device with

/system/apex/com.android.runtime is labeled as runtime_apex_dir
and init is allowed to mount on it.
When TARGET_FLATTEN_APEX is true (= ro.apex.updatable is unset or set to
false), apexd is not used to activate the built-in flattened APEXes.
Init simply bind-mounts /system/apex to /apex.
However, there is a special case here. The runtime APEX is installed as
either /system/apex/com.android.runtime.debug or
/system/apex/com.android.runtime.release, whereas it should be activated
on /apex/com.android.runtime - without the .debug or .release suffix.
To handle that case, the build system creates an empty directory
/system/apex/com.android.runtime and the .debug or .release directory
is bind-mounted to the empty directory by init at runtime.

The space between 2K and 16K in /misc is currently reserved for vendor's
use (as claimed in bootloader_message.h), but we don't allow vendor
module to access misc_block_device other than vendor_init.
The change in the topic adds a `misc_writer` tool as a vendor module,
which allows writing data to the vendor space to bridge the gap in the
short term. This CL adds matching labels to grant access.
Long term goal is to move /misc as vendor owned, then to provide HAL
access from core domain (b/132906936).
