This CL lists all the exported platform properties in
private/exported_property_contexts.
Additionally accessing core_property_type from vendor components is
restricted.
Instead public_readable_property_type is used to allow vendor components
to read exported platform properties, and accessibility from
vendor_init is also specified explicitly.
Note that whitelisting would be applied only if
PRODUCT_COMPATIBLE_PROPERTY is set on.
Bug: 38146102
Test: tested on walleye with PRODUCT_COMPATIBLE_PROPERTY=true

We rely on vendors to label all dependencies of healthd/charger under
/sys/class/power_supply with sysfs_batteryinfo type.
Bug: 65643247
Bug: 32659667
Test: boots without denials from healthd, to sysfs_batteryinfo or to
sysfs_msm_subsys.
Test: charging with device turned off works without /sys denials.

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;
Boot ARC++ on a device with the 4.12 kernel.

/sys/power/state is labled as sysfs_power now. Allow charger to
write to it instead of writing to sysfs.
Test: no denials for charger on this file

healthd is being split into 'charger' and 'healthd' processes, that
will never run together. 'charger' is to be run only in charge-only
and recovery, while healthd runs with Android.
While they both share much of battery monitoring code, they both now
have reduced scope. E.g. 'charger', doesn't need to use binder anymore
and healthd doesn't need to do charging ui animation. So, amend the
SEPolicy for healthd to reduce it's scope and add a new one for charger.
Test: Tested all modes {recovery, charger-only, android} with new policy
