This is to fix selinux denials on incident-helper-cmd.
incident-helper-cmd is a Java program spawn from app_process. There are
currently some selinux denials because app_process tries to read boot
flags, read dalvik cache, run JIT and exec from JIT cache.
This change:
- allows incidentd to read the runtime feature flag properties. This is
a normal behavior during app_process startup
- allows incidentd to lock a few java libraries under
/apex/com.android.art. Again, this is normal when ART starts
- mutes denial of writing to and exec from dalvik cache / JIT cache

This set of patches adds a way for the perfetto command line client to
save a trace to a hardcoded location,
/data/misc/perfetto-traces/incident-trace, and call into incidentd to
start a report, which will include said trace in a new section.
This is not a long-term solution, and is structured to minimize changes
to perfetto and incidentd. The latter is currently architected in a way
where it can only pull pre-defined information out of the system, so
we're resorting to persisting the intermediate results in a hardcoded
location.
This will introduce at most two more linked files at the same time.

(cherry picked from commit ce3a33ff18)
Previously we dumped the data into dropbox. This improves a couple
things:
- We write into dropbox via the fd, so dropbox doesn't pull from the
incidentd directory anymore.
- There is a new API to for priv apps to explicitly read incident
reports. That gives incidentd finer grained control over who can
read it (specifically, it only allows apps to access the incident
reports they requested, or were requested for them via statsd,
instead of getting DUMP and reading whatever they want from
dropbox).

system_file_type is a new attribute used to identify files which exist
on the /system partition. It's useful for allow rules in init, which are
based off of a blacklist of writable files. Additionally, it's useful
for constructing neverallow rules to prevent regressions.
Additionally, add commented out tests which enforce that all files on
the /system partition have the system_file_type attribute. These tests
will be uncommented in a future change after all the device-specific
policies are cleaned up.
Test: Device boots and no obvious problems.

This moves mediacodec to vendor so it is replaced with
hal_omx_server. The main benefit of this is that someone
can create their own implementation of mediacodec without
having to alter the one in the tree. mediacodec is still
seccomp enforced by CTS tests.

In kernel 4.7, the capability and capability2 classes were split apart
from cap_userns and cap2_userns (see kernel commit
8e4ff6f228e4722cac74db716e308d1da33d744f). Since then, Android cannot be
run in a container with SELinux in enforcing mode.
This change applies the existing capability rules to user namespaces as
well as the root namespace so that Android running in a container
behaves the same on pre- and post-4.7 kernels.
This is essentially:
1. New global_capability_class_set and global_capability2_class_set
that match capability+cap_userns and capability2+cap2_userns,
respectively.
2. s/self:capability/self:global_capability_class_set/g
3. s/self:capability2/self:global_capability2_class_set/g
4. Add cap_userns and cap2_userns to the existing capability_class_set
so that it covers all capabilities. This set was used by several
neverallow and dontaudit rules, and I confirmed that the new
classes are still appropriate.
Test: diff new policy against old and confirm that all new rules add
only cap_userns or cap2_userns;

On PRODUCT_FULL_TREBLE devices, non-vendor domains (except vendor
apps) are not permitted to use Binder. This commit thus:
* groups non-vendor domains using the new "coredomain" attribute,
* adds neverallow rules restricting Binder use to coredomain and
appdomain only, and
* temporarily exempts the domains which are currently violating this
rule from this restriction. These domains are grouped using the new
"binder_in_vendor_violators" attribute. The attribute is needed
because the types corresponding to violators are not exposed to the
public policy where the neverallow rules are.
