Move zygote policy to private This leaves only the existence of zygote domain and its executable's zygote_exec file label as public API. All other rules are implementation details of this domain's policy and are thus now private. Test: Device boot, apps (untrusted_app, system_app, platform_app, priv_app) work fine. No new denials.

Properly Treble-ize tmpfs access This is being done in preparation for the migration from ashmem to memfd. In order for tmpfs objects to be usable across the Treble boundary, they need to be declared in public policy whereas, they're currently all declared in private policy as part of the tmpfs_domain() macro. Remove the type declaration from the macro, and remove tmpfs_domain() from the init_daemon_domain() macro to avoid having to declare the *_tmpfs types for all init launched domains. tmpfs is mostly used by apps and the media frameworks. Bug: 122854450 Test: Boot Taimen and blueline. Watch videos, make phone calls, browse internet, send text, install angry birds...play angry birds, keep playing angry birds...

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.
