The implementation for NETLINK_FIREWALL and NETLINK_IP6_FW protocols
was removed from the kernel in commit
d16cf20e2f2f13411eece7f7fb72c17d141c4a84 ("netfilter: remove ip_queue
support") circa Linux 3.5.  Unless we need to retain compatibility
for kernels < 3.5, we can drop these classes from the policy altogether.

Possibly the neverallow rule in app.te should be augmented to include
the newer netlink security classes, similar to webview_zygote, but
that can be a separate change.

Test: policy builds

Since it was introduced it caused quite a few issues and it spams the
SElinux logs unnecessary.

The end goal of the audit was to whitelist the access to the
interpreter. However that's unfeasible for now given the complexity.

Test: devices boots and everything works as expected
      no more auditallow logs

This leaves only the existence of appdomain attribute as public API.
All other rules are implementation details of this attribute's policy
and are thus now private.

Test: Device boot, apps (untrusted_app, system_app, platform_app,
      priv_app) work fine. No new denials.

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.
