20151072a7 Restrict access to ro.serialno and ro.boot.serialno
This restricts access to ro.serialno and ro.boot.serialno, the two
system properties which contain the device's serial number, to a
select few SELinux domains which need the access. In particular, this
removes access to these properties from Android apps. Apps can access
the serial number via the public android.os.Build API. System
properties are not public API for apps.

The reason for the restriction is that serial number is a globally
unique identifier which cannot be reset by the user. Thus, it can be
used as a super-cookie by apps. Apps need to wean themselves off of
identifiers not resettable by the user.

Test: Set up fresh GMS device, install some apps via Play, update some apps, use Chrome
Test: Access the device via ADB (ADBD exposes serial number)
Test: Enable MTP over USB, use mtp-detect to confirm that serial number is reported in MTP DeviceInfo

2e00e6373f sepolicy: add version_policy tool and version non-platform policy.
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.

b5f5931e8c Added permissions for the dumpstate service.
- Allow dumpstate to create the dumpservice service.
- Allow System Server and Shell to find that service.
- Don't allow anyone else to create that service.
- Don't allow anyone else to find that service.

cc39f63773 Split general policy into public and private components.
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.
