- Add logd rules.

This was originally used for the /data/fdAlbum
file. Device specific policy properly labels the
file as camera_data_file either during its
initial creation (type_transition rule) or with
a single restorecon call in the respective init.*.rc
file.

/data/media presently is left in system_data_file, which requires
anything that wants to write to it to be able to write to system_data_file.
Introduce a new type for /data/media, media_rw_data_file (to match
the media_rw UID assigned to it and distinguish it from /data/misc/media
which has media UID and media_data_file type), and allow access to it.

We allow this for all platform app domains as WRITE_MEDIA_STORAGE permission is granted
to signature|system.  We should not have to allow it to untrusted_app.

Set up type transitions in sdcardd to automatically label any directories
or files it creates with the new type.

lmkd low memory killer daemon

The kernel low memory killer logic has been moved to a new daemon
called lmkd.  ActivityManager communicates with this daemon over a
named socket.

This is just a placeholder policy, starting off in unconfined_domain.

Limit the ability to write to the files that configure kernel
usermodehelpers and security-sensitive proc settings to the init domain.
Permissive domains can also continue to set these values.

The current list is not exhaustive, just an initial set.
Not all of these files will exist on all kernels/devices.
Controlling access to certain kernel usermodehelpers, e.g. cgroup
release_agent, will require kernel changes to support and cannot be
addressed here.

Use more general type names for the contents of /data/misc/camera and
/data/misc/audio.  These were the names used in our policy until 4.3
was released, at which point we switched to be consistent with AOSP.
However, the Galaxy S4 4.2.2 image, Galaxy S4 4.3 image, and
Galaxy Note 3 4.3 image all shipped with policies using _data_file names
because they were based on our older policy.  So we may as well switch
AOSP to these names.

Not sure if in fact these could be all coalesced to the new media_data_file
type for /data/misc/media introduced by
Ic374488f8b62bd4f8b3c90f30da0e8d1ed1a7343.

Options to fix already existing devices, which would only apply
to Nexus devices with 4.3 or 4.4 at this point:
1) Add restorecon_recursive /data/misc/audio /data/misc/camera to either
the system/core init.rc or to the device-specific init.*.rc files.
-or-
2) Add a typealias declaration in the policy to remap the old type names.
to the new ones.  Then existing types on persistent storage will be
remapped internally to the new ones.
-or-
3) Some sort of relabeld.

Option #2 is implemented by this change.
