The treble compatibility tests check for policy differences between old
and new policy.  To do this correctly, we must not modify the policy which
represents the older policies.  Move the files meant to be changed to a
different location from the ones that are not meant to be touched to avoid
any undesired changes to old policy, e.g. commit:

untrusted_app_visible_hwservice was an attribute that was meant to
give partners time to add their HALs to AOSP.  It was removed from mr1
and so needs to be accounted for in the compatibility mapping.

On Full Treble devices, servicemanager should only service
services from the platform service_contexts file.

Created new type to separate plat_ and nonplat_service_contexts,
and added new type to mapping (although I don't think this type
should have been used by vendors).

A new API [getNamesForUids] was recently added to the PackageManager
and this API needs to be accessible to native code. However, there
were two constraints:
1) Instead of hand-rolling the binder, we wanted to auto generate
the bindings directly from the AIDL compiler.
2) We didn't want to expose/annotate all 180+ PackageManager APIs
when only a single API is needed.
So, we chose to create a parallel API that can be used explicitly
for native bindings without exposing the entirety of the
PackageManager.

Commit: ec3b6b7e added a new daemon

Commit: 3eed3eac added the compatibility
statement for the new mediaprovider app domain, but it missed another
new, private type, mediaprovider_tmpfs, that is automatically created for

private, they do not need to be added to the actual mapping (vendor policy
cannot use it).

This reinstates the exception for netd_stable_secret_prop, which
was added after O sepolicy freeze. This exception, along with the
corresponding core sepolicy change, was reverted in order to
allow these policies to be added to per-device sepolicy.

Platform SELinux policy may be updated without a corresponding
update to non-platform policy.  This is meant to be accomplished by
maintaining a compatibility mapping file which will be built along
with the current platform policy to link older non-platform policy.

Introduce an example vendor policy built from 26.0 public policy and
make sure that the current platform policy and mapping file, for that
version, build with it.  Add this as a dependency for the
selinux_treble_tests, which are meant to ensure treble properties,
ultimately to provide this compatibility guarantee.

Bug: 36899958
Test: Current platform policy builds with oc-dev vendor policy and
oc-dev mapping file.  Removed private type with no effect.  Removed
public type without corresponding mapping entry causes build to fail.

Commit: 78e595de added a new hwservice,

domain_deprecated is a private attribute, which means that none of
its rules will be copied to vendor policy.  Unfortunately, this

sufficient.
