This leaves only the existence of ephemeral_app domain as public API.
All other rules are implementation details of this domain's policy and
are thus now private. There are a few rules, defined by other domains'
files remaining in the public policy until the rules from these
domains also move to the private policy:
allow ephemeral_app_current appdomain:binder transfer;
allow ephemeral_app_current audioserver_current:binder transfer;
allow ephemeral_app_current drmserver_current:binder transfer;
allow ephemeral_app_current dumpstate_current:binder transfer;
allow ephemeral_app_current mediaserver_current:binder transfer;
allow ephemeral_app_current surfaceflinger_current:binder transfer;
allow ephemeral_app_current system_server_current:binder transfer;
Test: No change to policy according to sesearch, except for
disappearance of all allow rules from platform_app_current
attribute (as expected).

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.

Lock in the gains we've made so far in restricting access to generically
labeled /proc files. There's more we can do here, but let's avoid
inadvertent regressions.
Test: policy compiles. Only compile time assertions added.
