Subject: [PATCH] - AppOps/PrivacyGuard: New Sensor checks [native]
Add two AppOps for sensor access:
- OP_MOTION_SENSORS (default: ask, strict)
- OP_OTHER_SENSORS (default: allow)
This change updated the AppOPs binder for the newly defined Ops,
implements the logic for the sensors and adapts the logic for
checking the Ops, if an Op is not linked to a permission.
