Ephemeral apps are still apps with very similar capabilities, it makes
more sense to have them under appdomain and benefit from the shared
state (and all the neverallow rules) than to try and dupplicate them and
keep them in sync.

This is an initial move, there are parts of ephemeral_app that still
need to be locked down further and some parts of appdomain that should
be pushed down into the various app domains.

Test: Builds, ephemeral apps work without denials.

There were some auditallow rules left around in rild.te that had logs
showing nothing was triggering them. Thus the rules they were auditing
could be removed, as that's clear indication there's no use for them.
Having rules around that aren't being used does nothing except increase
attack surface and bloat sepolicy, and so should always be removed if
possible.

Test: The device boots

Revise policy, to allow init and system_server to configure,
clear, and read kernel trace events. This will enable us to
debug certain WiFi failures.

Note that system_server is restricted to only accessing
a wifi-specific trace instance. (Hence, system_server is
not allowed to interfere with atrace.) Moreover, even for
the wifi trace instance, system_server is granted limited
permissions. (system_server can not, e.g., change which
events are traced.)

Note also that init and system_server are only granted these
powers on userdebug or eng builds.

The init.te and system_server.te changes resolve the
following denials:

Some recent CLs changed the list of files that are installed in the
root directory.  Incremental builds have no way to uninstall files
that were previously installed, which results in old stray files lying
around.  If the root directory is contained in system.img, this causes
an error while building system.img:
error: build_directory_structure: cannot lookup security context for /service_contexts

Update CleanSpec.mk to remove files obsoleted by:
Ide67d37d85273c60b9e387e72fbeb87be6da306a
I7881af8922834dc69b37dae3b06d921e05206564
Ide67d37d85273c60b9e387e72fbeb87be6da306a

This is not seen on the incremental build servers because they run
make installclean between builds.

Previously we published appfuse mount points to apps and apps open
appfuse file by themselves. We changed the design and we don't allow
apps to access appfuse mount point. Instead system server opens a file
on appfuse mount points and passes FD to apps.

The change updates apps and system server policies to adopt new design.
