Clarify init_shell, shell, and su domain usage. init_shell domain is now only used for shell commands or scripts invoked by init*.rc files, never for an interactive shell. It was being used for console service for a while but console service is now assigned shell domain via seclabel in init.rc. We may want to reconsider the shelldomain rules for init_shell and whether they are still appropriate. shell domain is now used by both adb shell and console service, both of which also run in the shell UID. su domain is now used not only for /system/bin/su but also for adbd and its descendants after an adb root is performed.

Remove domain_deprecated from adbd and shell The extra permissions are not needed. Delete them. This change also adds read permission for /data/misc/zoneinfo back to all domains. libc refernces this directory for timezone related files, and it feels dangerous and of little value to try to restrict access. In particular, this causes problems when the shell user attempts to run "ls -la" to show file time stamps in the correct timezone.

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.
