Mediaextractor should only be operating on data passed directly to it.
It shouldn't be attempting to open /data files on it's own.
Add a neverallow statement (compile time assertion + CTS test) to ensure
this is the case.

Test: policy compiles. No runtime impact.

These denials are expected and the code has fallbacks to handle this
case.

Permit mediaextractor its own file source for apk and ringtone files.
Previously we fall back to the mediaserver file source.
This does not affect behavior as the fallback works fine; however,
the log messages may cause confusion.

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.

reflect the change from "mediaanalytics" to "mediametrics"
Also incorporates a broader access to the service -- e.g. anyone.
This reflects that a number of metrics submissions come from application
space and not only from our controlled, trusted media related processes.
The metrics service (in another commit) checks on the source of any
incoming metrics data and limits what is allowed from unprivileged
clients.

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.
