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.

Currently, we define 4 hardcoded init services to launch dumpstate with
different command-line options (since dumpstate must be launched by
root):

- bugreport
- bugreportplus
- bugreportwear
- bugreportremote

This approach does not scale well; a better option is to have just one
service, and let the framework pass the extra arguments through a system
property.

These APIs expose sensitive information via timing side channels. This
leaves access via the adb shell intact along with the current uses by
dumpstate, init and system_server.

The /proc/interrupts and /proc/stat files were covered in this paper:

https://www.lightbluetouchpaper.org/2016/07/29/yet-another-android-side-channel/

The /proc/softirqs, /proc/timer_list and /proc/timer_stats files are
also relevant.

Access to /proc has been greatly restricted since then, with untrusted
apps no longer having direct access to these, but stricter restrictions
beyond that would be quite useful.

Unless we modify sdcardfs to change contexts, we need these.

Remove this patch if sdcardfs is updated to change the

This permission was created mostly for dumpstate (so it can include
recovery files on bugreports when an OTA fails), but it was applied to
uncrypt and recovery as well (since it had a wider access before).

Grant access to cache_recovery_file where we previously granted access
to cache_file. Add auditallow rules to determine if this is really
needed.

- Add a new 'dumpstate' context for system properties. This context
  will be used to share state between dumpstate and Shell. For example,
  as dumpstate progresses, it will update a system property, which Shell
  will use to display the progress in the UI as a system
  notification. The user could also rename the bugreport file, in which
  case Shell would use another system property to communicate such
  change to dumpstate.
- Allow Shell to call 'ctl.bugreport stop' so the same system
  notification can be used to stop dumpstate.

Motivation: Domain is overly permissive. Start removing permissions
from domain and assign them to the domain_deprecated attribute.
Domain_deprecated and domain can initially be assigned to all
domains. The goal is to not assign domain_deprecated to new domains
and to start removing domain_deprecated where it is not required or
reassigning the appropriate permissions to the inheriting domain
when necessary.
