09e6abd91b initial dumpstate domain
Add the necessary rules to support dumpstate.
Start off initially in permissive until it has more testing.

Dumpstate is triggered by running "adb bugreport"

2a604adf1b Confine healthd, but leave it permissive for now.
Remove unconfined_domain() and add the allow rules required for
operation of healthd.  Restore the permissive declaration until
I8a3e0db15ec5f4eb05d455a57e8446a8c2b484c2 is applied to the 3.4
kernel.

Resolves the following denials in 4.4:

353c72e3b0 Move unconfined domains out of permissive mode.
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.
