Adding a new location for policy files under
/data, the new location is /data/security. The
new location is used before attempting to use
any other location.
This requires a new directory to be created by
the init script and an update to the location of
the property_contexts file for property service.

Allow userspace programs to create IPPROTO_ICMP sockets.
This socket type allows an unprivileged program to safely
send ICMP_ECHO messages and receive the corresponding
ICMP_ECHOREPLY messages, without relying on raw sockets or
setuid programs.
Please see http://lwn.net/Articles/443051/ for details.
In particular, this allows us to use a version of ping
which doesn't have any capabilities
(https://android-review.googlesource.com/52072).
In addition, this allows us to safely implement an IPv4 ICMP
based version of InetAddress.isReachable()
(https://code.google.com/p/android/issues/detail?id=20106)

This will help get rid of android_aid.h in the kernel.
The group of the proc entries will be used in place of the default
values picked up by the xt_qtaguid netfilter module
(AID_NET_BW_STATS, AID_NET_BW_ACCT).
This change has no effect until the matching kernel changes are submitted.

This is necessary for some HWC hals to be able to communicate with
secure side to grant protected access to hardware owned by the
hwc. This is necessary on some architectures to grant access to
secure buffers to overlay/csc hardware

When vold mounts things in /mnt/secure/staging, it expects to MS_MOVE
those mountpoints when vetting is finished. However, the kernel
doesn't allow MS_MOVE when the source is shared to child namespaces.
To work around this, create a tmpfs at /mnt/secure and mark it as
private (not shared). Verified that vold can now successfully move
from the staging area.

Define /storage as top-level concept, so that we enforce permissions
uniformly. Moves external storage paths from headers to per-device
environment variables. Added missing mount flags, and we no longer
have adb-specific external storage.

Also remove mount() from adb, since it can come online long before
data partition is ready. Set EXTERNAL_STORAGE environment variable
to point to owner for backwards compatibility.

Remount rootfs as recursively shared, so that mount changes are
propagated into child namespaces. Mount external storage for access
from adb.
Clean multi-user dependencies for use in Dalvik. Also define
external storage paths.

To support runtime policy management, add support for reloading
policy from /data/system. This can be triggered by setting the
selinux.loadpolicy property to 1, whether from init.rc after
mounting /data or from the system_server (e.g. upon invocation of
a new device admin API for provisioning policy). ueventd and
installd are restarted upon policy reloads to pick up the new
policy configurations relevant to their operation.

Set the security context for the init process.
Restore the security contexts of /cache and /data in case they were reset.
Specify the security context for services launched from the rootfs since
we cannot label their executables.
If on the emulator, set a policy boolean and restore the context of
/sys/qemu_trace to allow accesses not normally permitted on a device.
