This new type will allow us to write finer-grained
policy concerning asec containers. Some files of
these containers need to be world readable.

We can read any efs_files, but can't look in the directory
containing them. Allow it.

Without this patch, high resolution movie playback is broken.

Permissive domains are only intended for development.
When a device launches, we want to ensure that all
permissive domains are in, at a minimum, unconfined+enforcing.

Add FORCE_PERMISSIVE_TO_UNCONFINED to Android.mk. During
development, this flag is false, and permissive domains
are allowed. When SELinux new feature development has been
frozen immediately before release, this flag will be flipped
to true. Any previously permissive domains will move into
unconfined+enforcing.

This will ensure that all SELinux domains have at least a
minimal level of protection.

Unconditionally enable this flag for all user builds.

mediaserver needs the ability to read media_rw_data_file files.
Allow it. Similarly, this is also needed for drmserver. Addresses
the following denials:

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.
