This unbreaks user builds broken by recently landed changes to secilc
which is now aggressively removing attributes which aren't used in
allow rules, even when they are used in other places, such as being
referenced from *_contexts files.

User builds are broken by vndservice_manager_type not being found when
checkfc is run for *vndservice_contexts targets.

This adds restrictions on which domains can register this HwBinder
service with hwservicemanager and which domains can obtain tokens for
this service from hwservicemanager.

Test: Use Google Camera app to take HDR+ photo, conventional photo,
      record video with sound, record slow motion video with sound.
      Check that the photos display correctly and that videos play
      back fine and with sound. Check that there are no SELinux
      denials to do with camera.

hwservicemanager can check hwservice_contexts files
both from the framework and vendor partitions.

Initially, have a wildcard '*' in hwservice_contexts
that maps to a label that can be added/found from
domain. This needs to be removed when the proper policy
is in place.

Also, grant su/shell access to hwservicemanager list
operations, so tools like 'lshal' continue to work.

Attributes added to the policy by the policy compiler are causing
performance issues. Telling the compiler to expand these
auto-generated attributes to their underlying types prevents
preemtion during policy lookup.

With this patch the number of attributes in policy drops from
845 to 475. The number of attributes assigned to the bluetooth domain
drops from 41 to 11.

All HALs which are represented by hal_* attributes in SELinux policy
are required to run in binderized mode on Treble devices. This commit
thus makes the SELinux policy for Treble devices no longer associate
domains in hal_x_client with hal_x attribute, which is what was
granting domains hosting clients of hal_x the rules needed to run this
HAL in-process. The result is that core components have now less
access.

This commit has no effect on non-Treble devices.

commit 552fb537 fixed an undefined
module error by removing the module when not defined (on non-treble
devices), but the sepolicy build on non-treble devices was changed
to rely on the split treble files, even though the split is not used.
Change this so that the file is always present, to allow policy
compilation.

Test: policy fully builds.

(cherry picked from commit 8b9d93f2)

The original purpose of BOARD_SEPOLICY_VERS_DIR was to allow the
specification of an alternate platform public policy, primarily for
testing purposes.  This should not be a part of the released platform,
since the only public policy and corresponding mapping file construction
should be based on the current public platform policy, with compatibility
with vendor policy targeting previous versions provided by static mapping
files.  Its continued presence muddles the generation of mapping files by
potentially introducing a situation in which an incorrect mapping file is
generated.  Remove it.

Test: Device boots with compiled SELinux policy (SHA256s don't match for

Recovery is not meant to be versioned in the treble model, but rather
provided as part of the platform/framework component and self-sufficient.
Simplify its compilation by removing the attribute versioning steps, but
maintain device-specific policy, which is currently required for full
functionality.

As the platform progresses in the split SELinux world, the platform
will need to maintain mapping files back to previous platform versions
to maintain backwards compatibility with vendor images which have SELinux
policy written based on the older versions.  This requires shipping multiple
mapping files with the system image so that the right one can be selected.
Change the name and location of the mapping file to reflect this.  Also add
a file to the vendor partition indicating which version is being targeted that
the platform can use to determine which mapping file to choose.

Bug: 36783775
Test: Force compilation of sepolicy on-device with mapping file changed
to new location and name, using the value reported on /vendor.

a few domains that are defined in vendor policy and installed in
/vendor. These files MUST be a subset of the global 'vendor_file_type'

* changes:
  allow to load kernel modules from vendor partition
  SELinux changes for Treble Loadable Kernel Module

The kernel  modules under /vendor partition has been relabeled to vendor_file.
This CL allows for the modprobe to load modules labeled vendor_file.

Kernel modules are loaded in init.rc with following commands:
    exec u:r:modprobe:s0 -- /system/bin/modprobe -d /vendor/lib/modules MODULE
