System services differ in designed access level. Add attributes reflecting this
distinction and label services appropriately. Begin moving access to the newly
labeled services by removing them from tmp_system_server_service into the newly
made system_server_service attribute. Reflect the move of system_server_service
from a type to an attribute by removing access to system_server_service where
appropriate.

Revert the tightening of /proc/net access. These changes
are causing a lot of denials, and I want additional time to
figure out a better solution.
Addresses the following denials (and many more):
avc: denied { read } for comm="SyncAdapterThre" name="stats" dev="proc" ino=X scontext=u:r:untrusted_app:s0:c512,c768 tcontext=u:object_r:proc_net:s0 tclass=file

which occurs when a non-default SMS app sends an MMS. The message would be
stored into system automatically in MMS service (from phone process and phone
UID). The storing of the message involves the creation of
android.drm.DrmManagerClient instance.

Messenger can't send MMSes on the master branch. When Messenger sends
an MMS, it stores the message data in local file and publishes it
via a content provider. The URI is passed to the MMS API. The
MmsServiceBroker in system process gets the call and grant URI
permission to phone UID. The MmsService in phone process (and sharing
the phone UID) needs to read the URI to get message data to send.
Addresses the following denial:

Introduce a dhcp_prop type for properties that can be set by dhcp or system.
Drop the rild_prop vs radio_prop distinction; this was an early

This change removes the permissive line from unconfined
domains. Unconfined domains can do (mostly) anything, so moving
these domains into enforcing should be a no-op.
The following domains were deliberately NOT changed:
1) kernel
2) init
In the future, this gives us the ability to tighten up the
rules in unconfined, and have those tightened rules actually
work.
When we're ready to tighten up the rules for these domains,
we can:
1) Remove unconfined_domain and re-add the permissive line.
2) Submit the domain in permissive but NOT unconfined.
3) Remove the permissive line
4) Wait a few days and submit the no-permissive change.
For instance, if we were ready to do this for adb, we'd identify
a list of possible rules which allow adbd to work, re-add
the permissive line, and then upload those changes to AOSP.
After sufficient testing, we'd then move adb to enforcing.
We'd repeat this for each domain until everything is enforcing
and out of unconfined.

This prevents denials from being generated by the base policy.
Over time, these rules will be incrementally tightened to improve
security.
