This change only expands the existing permissions, so shouldn't regress
runtime behavior.

In kernel 4.7, the capability and capability2 classes were split apart
from cap_userns and cap2_userns (see kernel commit
8e4ff6f228e4722cac74db716e308d1da33d744f). Since then, Android cannot be
run in a container with SELinux in enforcing mode.

This change applies the existing capability rules to user namespaces as
well as the root namespace so that Android running in a container
behaves the same on pre- and post-4.7 kernels.

This is essentially:
  1. New global_capability_class_set and global_capability2_class_set
     that match capability+cap_userns and capability2+cap2_userns,
     respectively.
  2. s/self:capability/self:global_capability_class_set/g
  3. s/self:capability2/self:global_capability2_class_set/g
  4. Add cap_userns and cap2_userns to the existing capability_class_set
     so that it covers all capabilities.  This set was used by several
     neverallow and dontaudit rules, and I confirmed that the new
     classes are still appropriate.

Test: diff new policy against old and confirm that all new rules add
      only cap_userns or cap2_userns;
      Boot ARC++ on a device with the 4.12 kernel.

This attribute is being actively removed from policy. Since
attributes are not being versioned, partners must not be able to
access and use this attribute. Move it from private and verify in
the logs that rild and tee are not using these permissions.

The types need to be exported so userdebug system.img
can still build the policy with a user vendor.img at boot time.
All permissions and attributes for these types are still kept under
conditional userdebug_or_eng macro

Vendor and system components are only allowed to share files by
passing open FDs over HIDL. Ban all directory access and all file
accesses other than what can be applied to an open file:
stat/read/write/append.

This commit marks core data types as core_data_file_type and bans
access to non-core domains with an exemption for apps. A temporary
exemption is also granted to domains that currently rely on
access with TODOs and bug number for each exemption.

Make all platform tyeps public to start to prevent build breakage in any devices
that may have device-specific policy using these types.  Future changes will
need to be carefully made to ensure we properly limit types for use by
non-platform policy.

Test: Builds

Divide policy into public and private components.  This is the first
step in splitting the policy creation for platform and non-platform
policies.  The policy in the public directory will be exported for use
in non-platform policy creation.  Backwards compatibility with it will
be achieved by converting the exported policy into attribute-based
policy when included as part of the non-platform policy and a mapping
file will be maintained to be included with the platform policy that
maps exported attributes of previous versions to the current platform
version.

Eventually we would like to create a clear interface between the
platform and non-platform device components so that the exported policy,
and the need for attributes is minimal.  For now, almost all types and
avrules are left in public.

Test: Tested by building policy and running on device.

Start labeling the directory /sys/kernel/debug/tracing. The files
in this directory need to be writable to the shell user.

Remove global debugfs:file write access. This was added in the days
before we could label individual debugfs files.

Motivation: Domain is overly permissive. Start removing permissions
from domain and assign them to the domain_deprecated attribute.
Domain_deprecated and domain can initially be assigned to all
domains. The goal is to not assign domain_deprecated to new domains
and to start removing domain_deprecated where it is not required or
reassigning the appropriate permissions to the inheriting domain
when necessary.

When the toolbox domain was introduced, we allowed all domains to exec it
to avoid breakage.  However, only domains that were previously allowed the
ability to exec /system files would have been able to do this prior to the
introduction of the toolbox domain.  Remove the rule from domain.te and add
rules to all domains that are already allowed execute_no_trans to system_file.
Requires coordination with device-specific policy changes with the same Change-Id.
