The new binder_call() lines had to be added
because this change removes mediacodec from
binderservicedomain (on full-treble), hence
domains that could previously reach mediacodec
with binder_call(domain, binderservicedomain)
now need explicit calls instead.

The tee domain is a vendor domain. Thus it cannot be accessed by
non-vendor components over Unix domain sockets.

It appears that the rules granting this access are not needed.

This change associates all domains which are clients of Allocator HAL
with hal_allocator_client and the, required for all HAL client
domains, halclientdomain.

This enables this commit to remove the now unnecessary hwallocator_use
macro because its binder_call(..., hal_allocator_server) is covered by
binder_call(hal_allocator_client, hal_allocator_server) added in this
commit.

Unfortunately apps, except isolated app, are clients of Allocator HAL
as well. This makes it hard to use the hal_client_domain(...,
hal_allocator) macro because it translates into "typeattribute" which
currently does not support being provided with a set of types, such as
{ appdomain -isolated_app }. As a workaround, hopefully until
typeattribute is improved, this commit expresses the necessary
association operation in CIL. private/technical_debt.cil introduced by
this commit is appended into the platform policy CIL file, thus
ensuring that the hack has effect on the final monolithic policy.

P. S. This change also removes Allocator HAL access from isolated_app.
Isolated app shouldn't have access to this HAL anyway.

Test: Compiles

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.
