The untrusted apps should not directly access /dev/socket/mdnsd since
API level 34 (U). Only adbd and netd should remain to have access to
/dev/socket/mdnsd. For untrusted apps running with API level 33-, they
still have access to /dev/socket/mdnsd for backward compatibility.

Enforce new requirements on app with targetSdkVersion=30 including:
- No RTM_GETLINK on netlink route sockets.
Remove some of the repetitive descriptions in each untrusted_app_N.te
file, and instead refer to the description in

Used when mapping RTM_GETLINK messages to this new permission.
Users of netlink_route_sockets that do not use the net_domain()
macro will need to grant this permission as needed. Compatibility
with older vendor images is preserved by granting all vendor domains
access to this new permission in *.compat.cil files.

Grant for icmp_socket for devices with 4.14 or greater kernel, and
rawip_socket for devices with earlier kernels.

Vendor domains may use net_domain() so it should be moved to public
policy. This will allow removal of permissions such as rawip_socket
in future releases without breaking Treble compatiblity.

This leaves only the existence of netdomain attribute as public API.
All other rules are implementation details of this attribute's policy
and are thus now private.
Test: No change to policy according to sesearch, except for
disappearance of all allow rules to do with netdomain_current
and *_current attributes targeted when netdomain rules reference
public types.

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.
