    sepolicy: add version_policy tool and version non-platform policy. · 2e00e637
    dcashman authored
    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.
    Bug: 31369363
