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. Change-Id: Idef796c9ec169259787c3f9d8f423edf4ce27f8c
