From d0663b7dc73564744e89d5dd93675ff8929cc532 Mon Sep 17 00:00:00 2001

Subject: [PATCH] AppOps/PrivacyGuard: New Sensor checks [base]
Add two AppOps for sensor access:
- OP_MOTION_SENSORS (default: ask, strict)
- OP_OTHER_SENSORS (default: allow)
To avoid severe issues when setting selected Ops to 'ASK', the default
mode for apps with uid 1000 (system) will always get the 'allowed' mode
as default, same as com.android.systemui
