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.

(cherry picked from commit 0f81e066)

No core android component needs access to /dev/snd/{seq,timer}, but
currently audioserver, bootanim, init, system_server and ueventd have
access. Seq and timer have been the source of many bugs in the past
[1]. Giving these files new labels without explicitly granting access
removes access from audioserver, bootanim, and system_server.
Init and ueventd still require access for /dev setup.

TODO: Explore unsetting CONFIG_SND_TIMER device kernels.

Grant access to all processes and audit access. The end goal is to
whitelist all access to the interpreter. Several processes including
dex2oat, apps, and zygote were observed using libart, so omit them
from auditing and explicitly grant them access.

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.

Build serial is non-user resettable freely available device
identifier. It can be used by ad-netowrks to track the user
across apps which violates the user's privacy.

This change deprecates Build.SERIAL and adds a new Build.getSerial()
API which requires holding the read_phone_state permission.
The Build.SERIAL value is set to "undefined" for apps targeting
high enough SDK and for legacy app the value is still available.

In anticipation of fixing a loophole in the Linux kernel that allows
circumventing the execmem permission by using the ptrace interface,
this patch grants execmem permission on debuggable domains to
debuggerd. This will be required for setting software break points
once the kernel has been fixed.
