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.

Since hal_graphics_composer_default is now no longer
a member of binderservicedomain, these domains would
no longer be able to use filedescriptors from it.

* changes:
  suppress audit logs from rild's access to core domain through system()
  sepolicy: auditallow vendor components to execute files from /system
  vendor_shell: add sepolicy for vendor shell
  toolbox: add sepolicy for vendor toybox
  Do not allow priv_apps to scan all exec files

This change disables /dev/binder access to and by mediacodec on
full-Treble devices.

b/36604251 OMX HAL (aka mediacodec) uses Binder and even exposes a
	   Binder service

Adds a rule to audit vendor domains from executing programs from /system
with the exception of domains whitelisted in the rule.

Test: Boot sailfish
Test: Run SELinuxHostTests with the tests that checks for new violators
      (without the API check) to ensure it fails for sailfish. The API
      check will allow the test to skip the check.

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.

Test: Device boots -- no new denials
Test: Play movie using Google Play Movies and Netflix
Test: Play YouTube clip in YouTube app and in Chrome
Test: Unlock lock screen using fingerprint
Test: Using Google Camera, take a photo, an HDR+ photo, record a

Test: In all tests, no deials to do with hal_*, except pre-existing
      denials to do with hal_gnss.

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.

Specifying an empty module causes a build error, so make sure that
if there is no $(platform_mapping_file) the MODULE is not included.

Test: Makefiles parsed without error.
