Add a service_mananger class with the verb add.
Add a type that groups the services for each of the
processes that is allowed to start services in service.te
and an attribute for all services controlled by the service
manager. Add the service_contexts file which maps service
name to target label.

Only keystore itself should be reading / writing it's files.
Remove keystore file access from other SELinux domains, including
unconfined. Add neverallow rules to protect against regressions.
Allow init limited access to recurse into keystore's directory.

On manta, the keystore CTS tests are failing, because
keystore isn't allowed to talk to the tee. Allow it.
I've only seen this bug on manta, but it seems appropriate
for all domains.
Fixes the following denial:

This is causing runtime restarts on flo/deb when uninstalling
some APKs. Revert while I investigate it.

This reverts commit 709d71836d.
Bug: 11518274
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.

Update policy for Android 4.2 / latest master.
Primarily this consists of changes around the bluetooth subsystem.
The zygote also needs further permissions to set up /storage/emulated.
adbd service now gets a socket under /dev/socket.
keystore uses the binder.
