Reason for revert: CPU HAL is no longer required because the CPU frequency sysfs files are stable Linux Kernel interfaces and could be read directly from the framework.

Removes all references to vendor_service in policy except the
definition of this type, which also needs to be removed by
clients.
We don't need this because interface type shouldn't be associated
with where they are served. We can serve HALs from anywhere if they are
implemented in software.

Goal is to gain a better handle on who has access to which maps
and to allow (with bpfloader changes to create in one directory
and move into the target directory) per-map selection of
selinux context, while still having reasonable defaults for stuff
pinned directly into the target location.
BPFFS (ie. /sys/fs/bpf) labelling is as follows:
subdirectory selinux context mainline usecase / usable by
/ fs_bpf no (*) core operating system (ie. platform)
/net_private fs_bpf_net_private yes, T+ network_stack
/net_shared fs_bpf_net_shared yes, T+ network_stack & system_server
/netd_readonly fs_bpf_netd_readonly yes, T+ network_stack & system_server & r/o to netd
/netd_shared fs_bpf_netd_shared yes, T+ network_stack & system_server & netd [**]
/tethering fs_bpf_tethering yes, S+ network_stack
/vendor fs_bpf_vendor no, T+ vendor
* initial support for bpf was added back in P,
but things worked differently back then with no bpfloader,
and instead netd doing stuff by hand,
bpfloader with pinning into /sys/fs/bpf was (I believe) added in Q
(and was definitely there in R)
** additionally bpf programs are accesible to netutils_wrapper
for use by iptables xt_bpf extensions
'mainline yes' currently means shipped by the com.android.tethering apex,
but this is really another case of bad naming, as it's really
the 'networking/connectivity/tethering' apex / mainline module.
Long term the plan is to merge a few other networking mainline modules
into it (and maybe give it a saner name...).
The reason for splitting net_private vs tethering is that:
S+ must support 4.9+ kernels and S era bpfloader v0.2+
T+ must support 4.14+ kernels and T beta3 era bpfloader v0.13+
The kernel affects the intelligence of the in-kernel bpf verifier
and the available bpf helper functions. Older kernels have
a tendency to reject programs that newer kernels allow.
/ && /vendor are not shipped via mainline, so only need to work
with the bpfloader that's part of the core os.

By default, HAL's services are not accessible by dumpstate. HIDL
implementations were silenced via a dontaudit on hwservice_manager. But
AIDL implementations will trigger a denial, unless authorized via
`dump_hal`. Mark all HAL services with a new attribute
`hal_service_type` so they can be ignored by dumpstate.

This is the common type for domains that executes charger's
functionalities, including setting and getting necessary properties,
permissions to maintain the health loop, writing to kernel log, handling
inputs and drawing screens, etc.
Permissions specific to the system charger is not moved.
Also enforce stricter neverallow rules on charger_{status,config}_prop.
For charger_config_prop, only init / vendor_init can set.
For charger_status_prop, only init / vendor_init / charger / health HAL
can set.
For both, only init / vendor_init / charger / dumpstate / health HAL
can get.
(Health HAL is determined by the intersection of charger_type and
hal_health_server.)
A follow up CL will be added to add charger_type to hal_health_default,
the default domain for health HAL servers. Vendors may add charger_type
to their domains that serves the health AIDL HAL as well.

policies no longer rely on these attributes.
The difference between the previous versions of this patch and the

Addressing b/194450129 requires configuring the I/O scheduler and the
queue depth of loop devices. Doing this in a generic way requires
iterating over the block devices under /sys/class/block and also to
examine the properties of the boot device (/dev/sda). Hence this patch
that allows 'init' and 'apexd' to read the properties of all block
devices. The patch that configures the queue depth is available at
https://android-review.googlesource.com/c/platform/system/core/+/1783847.
Test: Built Android images, installed these on an Android device and verified that modified init and apexd processes do not trigger any SELinux complaints.

We ended up with 4 labels for specific APEX files that were all
identical; I've replaced them with a single one
(apex_system_server_data_file).
Additionally I created an attribute to be applied to a "standard" APEX
module data file type that establishes the basics (it can be managed
by vold_prepare_subdirs and apexd), to make it easier to add new such
types - which I'm about to do.

Any FUSE filesystem will receive the 'fuse' type when mounted. It is
possible to change this behaviour by specifying the "context=" or
"fscontext=" option in mount().
Because 'fuse' has historically been used only for the emulated storage,
it also received the 'sdcard_type' attribute. Replace the 'sdcard_type'
attribute from 'fuse' with the new 'fusefs_type'. This attribute can be
attached on derived types (such as app_fusefs).
This change:
- Remove the neverallow restriction on this new type. This means any
custom FUSE implementation can be mounted/unmounted (if the correct
allow rule is added). See domain.te.
- Change the attribute of 'fuse' from 'sdcard_type' to 'fusefs_type'.
See file.te.
- Modify all references to 'sdcard_type' to explicitly include 'fuse'
for compatibility reason.

Android R launching devices and newer must not ship with debugfs

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.

One of the advantages of the DMA-BUF heaps framework over
ION is that each heap is a separate char device and hence
it is possible to create separate sepolicy permissions to restrict
access to each heap.
In the case of ION, allocation in every heap had to be done through
/dev/ion which meant that there was no away to restrict allocations in
a specific heap.
This patch intends to restrict coredomain access to only approved
categories of vendor heaps. Currently, the only identified category
as per partner feedback is the system-secure heap which is defined
as a heap that allocates from protected memory.
Test: Build, video playback works on CF with ION disabled and
without sepolicy denials
