The rules for the two types were the same and /data/app-ephemeral is
being removed. Remove these types.
Test: Builds

Introduce the add_service() macro which wraps up add/find
permissions for the source domain with a neverallow preventing
others from adding it. Only a particular domain should
add a particular service.
Use the add_service() macro to automatically add a neverallow
that prevents other domains from adding the service.
mediadrmserver was adding services labeled mediaserver_service.
Drop the add permission as it should just need the find
permission.
Additionally, the macro adds the { add find } permission which
causes some existing neverallow's to assert. Adjust those
neverallow's so "self" can always find.
Test: compile and run on hikey and emulator. No new denials were
found, and all services, where applicable, seem to be running OK.

As of https://android-review.googlesource.com/324092, ephemeral_app is
now an appdomain, so places where both appdomain and ephemeral_app are
granted the same set of rules can be deleted.
Test: policy compiles.

In order to support platform changes without simultaneous updates from
non-platform components, the platform and non-platform policies must be
split. In order to provide a guarantee that policy written for
non-platform objects continues to provide the same access, all types
exposed to non-platform policy are versioned by converting them and the
policy using them into attributes.
This change performs that split, the subsequent versioning and also
generates a mapping file to glue the different policy components
together.
Test: Device boots and runs.

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.
