Device Owner, a special kind of device admin
A Device Owner cannot be uninstalled and is available to all users. It must
be registered before the device_provisioned flag is set.
Device admins can be disabled until used, but visible to device policy
manager, so that users wont be bothered with update requests.
Opened up a few related APIs for use by a system-installed Device Owner.
