Copy the final system sepolicy from oc-dev to its prebuilt dir
corresponding to its version (26.0) so that we can uprev policy and
start maintaining compatibility files, as well as use it for CTS
tests targeting future platforms.
Bug: 37896931
Test: none, this just copies the old policy.

On Marlin ~120 ms of time is spent relabeling /sys/devices/system/cpu
every time we come out of suspend. Moving from file_contexts to
genfs_contexts as the labeling mechanism knocks this down to ~3 ms.
Bug: 32938130
Test: build and boot Marlin. Verify that files in
/sys/devices/system/cpu have the proper label before and after
suspend.

It appears that selinux requires the write permission to receive
a writable pipe from dumpstate, for unclear reasons. Add the permission
for now.

modprobe domain was allowed to launch vendor toolbox even if its a
coredomain. That violates the treble separation. Fix that by creating a
separate 'vendor_modprobe' domain that init is allowed to transition to
through vendor_toolbox.

(cherry picked from commit 9e366a0e49)
With project Treble, we're relying heavily on attributes for
permission inheritance and enforcement of separation between
platform and vendor components.
We neead tests that verify those attributes are correctly applied.
This change adds the framework for those tests including a wrapper
around libsepol for loading and querying policy, and a python module
for running tests on policy and file_contexts.
Included with the testing framework is a test asserting that the
coredomain attribute is only applied to core processes. This
verification is done using the following rules:
1. Domain's entrypoint is on /system - coredomain
2. Domain's entrypoint is on /vendor - not coredomain
3. Domain belongs to a whitelist of known coredomains - coredomain
In a subsequent commit these tests will be applied at build time.
However, I first need to fix existing Treble violations exposed by
this test. These tests will also be applied during CTS.
Test: LD_PRELOAD=$ANDROID_HOST_OUT/lib64/libsepolwrap.so python \
treble.py -p $OUT/vendor/etc/selinux/precompiled_sepolicy \
-f $OUT/vendor/etc/selinux/nonplat_file_contexts \
