reflect the change from "mediaanalytics" to "mediametrics"

Also incorporates a broader access to the service -- e.g. anyone.
This reflects that a number of metrics submissions come from application
space and not only from our controlled, trusted media related processes.
The metrics service (in another commit) checks on the source of any
incoming metrics data and limits what is allowed from unprivileged
clients.

This CLs adds SElinux policies necessary to compile secondary dex files.

When an app loads secondary dex files via the base class loader the
files will get reported to PM. During maintance mode PM will compile the
secondary dex files which were used via the standard installd model
(fork, exec, change uid and lower capabilities).

What is needed:
dexoptanalyzer - needs to read the dex file and the boot image in order
to decide if we need to actually comppile.
dex2oat - needs to be able to create *.oat files next to the secondary
dex files.

Test: devices boots
      compilation of secondary dex files works without selinux denials

Addresses the following denial:

  avc: denied { read } for name="cache" dev="dm-0" ino=2755
  scontext=u:r:priv_app:s0:c512,c768 tcontext=u:object_r:cache_file:s0
  tclass=lnk_file permissive=0

which occurs when a priv-app attempts to follow the /cache symlink. This
symlink occurs on devices which don't have a /cache partition, but
rather symlink /cache to /data/cache.

Ephemeral apps cannot open files from external storage, but can be given
access to files via the file picker.

Test: ACTION_OPEN_DOCUMENTS from an ephemeral app returns a readable fd.
Change-Id: Ie21b64a9633eff258be254b9cd86f282db1509e8

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.

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:

It seems likely that there is no reason to keep around a number of
devices that are configured to be included into the pixel kernels. Init
and ueventd should be the only processes with r/w access to these
devices, so auditallow rules have been added to ensure that they aren't
actually used.

/dev/keychord was given its own type since it's one of the few character
devices that's actually legitimately used and would cause log spam in
the auditallow otherwise.
