Add policy for 'blank_screen'. This util allows init to turn off the screen without any binder dependencies. Bug: 70846424 Test: manual + init use Change-Id: I4f41a966d6398e959ea6baf36c2cfe6fcebc00de 2018-01-19 22:00:42 +01:00			`type blank_screen, domain, coredomain;`
Introduce system_file_type 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.
