On PRODUCT_FULL_TREBLE devices, non-vendor domains (coredomain) and
vendor domain are not permitted to connect to each other's sockets.
There are two main exceptions: (1) apps are permitted to talk to other
apps over Unix domain sockets (this is public API in Android
framework), and (2) domains with network access (netdomain) are
permitted to connect to netd.
This commit thus:
* adds neverallow rules restricting socket connection establishment,
* temporarily exempts the domains which are currently violating this
rule from this restriction. These domains are grouped using the new
"socket_between_core_and_vendor_violators" attribute. The attribute
is needed because the types corresponding to violators are not
exposed to the public policy where the neverallow rules are.

This switches most remaining HALs to the _client/_server approach.
To unblock efforts blocked on majority of HALs having to use this
model, this change does not remove unnecessary rules from clients of
these HALs. That work will be performed in follow-up commits. This
commit only adds allow rules and thus does not break existing
functionality.
The HALs not yet on the _client/_server model after this commit are:
* Allocator HAL, because it's non-trivial to declare all apps except
isolated apps as clients of this HAL, which they are.
* Boot HAL, because it's still on the non-attributized model and I'm
waiting for update_engine folks to answer a couple of questions
which will let me refactor the policy of this HAL.

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.

After checking the auditallow logs for the rule being monitored, it's
clear that the rule is not in use and can be removed. All unused rules
should be removed, as they present needless additional attack vectors.
Test: The device boots.

Commit fee49159e introduced the net_radio_prop and system_radio_prop
properties, and added allow rules for backwards compatibility. In
addition, auditallow rules were added to see if the allow rules were
necessary.
The auditallow rules for radio net_radio_prop are triggering, so it's
clear these properties are being set by the radio process. Drop the
auditallow statement.
Test: policy compiles.

app_domain was split up in commit: 2e00e6373f to
enable compilation by hiding type_transition rules from public policy. These
rules need to be hidden from public policy because they describe how objects are
labeled, of which non-platform should be unaware. Instead of cutting apart the
app_domain macro, which non-platform policy may rely on for implementing new app
types, move all app_domain calls to private policy.

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.
