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.

Test: Boot Taimen and blueline. Watch videos, make phone calls, browse
internet, send text, install angry birds...play angry birds, keep
playing angry birds...

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.

Replace the global debuggerd with a per-process debugging helper that
gets exec'ed by the process that crashed.

Test: crasher/crasher64, `debuggerd <pid>`, `kill -ABRT <pid>`

This removes access to Bluetooth system properties from arbitrary
SELinux domains. Access remains granted to init, bluetooth, and
system_app domains. neverallow rules / CTS enforce that access is not
granted to Zygote and processes spawned from Zygote expcept for
system_app and bluetooth.
The reason is that some of these properties may leak persistent
identifiers not resettable by the user.
Test: Bluetooth pairing and data transfer works

webview_zygote needs to preload the WebView implementation, which may be
an installed APK, so must be able to read and execute code from inside
the APK.
Also add additional neverallow assertions to strengthen some
restrictions on this domain.
Test: WebView apps work after installing a WebView APK.

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.
Test: m
Test: angler boots
