status and get user authorization to share bugreports by calling
system_server.

This attribute is being actively removed from policy. Since
attributes are not being versioned, partners must not be able to
access and use this attribute. Move it from private and verify in
the logs that rild and tee are not using these permissions.

(cherry picked from commit ca0979792f)
On PRODUCT_FULL_TREBLE devices, non-vendor domains (except vendor
apps) are not permitted to use Binder. This commit thus:
* groups non-vendor domains using the new "coredomain" attribute,
* adds neverallow rules restricting Binder use to coredomain and
appdomain only, and
* temporarily exempts the domains which are currently violating this
rule from this restriction. These domains are grouped using the new
"binder_in_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.

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.

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.
