[1/2] base: Add ADB Paranoia mode

ADB Paranoia mode will reboot the device in the event of the following:

- The device is locked
- An ADB master device is connected
- ADB Paranoia mode is enabled in Development menu

Used in conjunction with device encryption, this should offer decent
protection against malicious adversaries with basic physical access to
your device. This will not help if your device has hardware level
exploits that can be used without rebooting the device, and without
connecting ADB.
