Confine the mediaserver domain, restoring our rules for it,
but leave it permissive until sufficient testing has been
performed.

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.

Two new types are introduced:
sdcard_internal
sdcard_external
The existing type of sdcard, is dropped and a new attribute
sdcard_type is introduced.
The boolean app_sdcard_rw has also been changed to allow for
controlling untrusted_app domain to use the internal and external
sdcards.

The binder_transfer_binder hook was changed in the kernel, obsoleting
the receive permission and changing the target of the transfer permission.
Update the binder-related policy to match the revised permission checking.
