Add the "webview_zygote" domain. The webview_zygote is a new unprivileged zygote and has its own sockets for listening to fork requests. However the webview_zygote does not run as root (though it does require certain capabilities) and only allows dyntransition to the isolated_app domain.

Move webview_zygote policy to private This leaves only the existence of webview_zygote domain and its executable's webview_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 boots, with Multiproces WebView developer setting enabled, apps with WebView work fine. No new denials. Bug: 31364497 Change-Id: I179476c43a50863ee3b327fc5155847d992a040d 2017-01-26 13:45:31 -08:00			`type webview_zygote, domain;`

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.
