This also includes some portability changes so that the package can be
imported with the top level runtime.

The variables that were defined at the top of the apparmor profile are best
pulled in via the <tunables/global> include.

Add 'pid' variable pointing to 'self' to allow parsing of profile to succeed

Encountered problems on 14.04 relating to signals between container
processes being blocked by apparmor. The base abstraction contains
appropriate rules to allow this communication.

This also improves the logic around formatting the labels for selinux
Docker-DCO-1.1-Signed-off-by: Michael Crosby <michael@crosbymichael.com> (github: crosbymichael)
When the code attempts to set the ProcessLabel, it checks if SELinux Is
enabled. We have seen a case with some of our patches where the code
is fooled by the container to think that SELinux is not enabled. Calling
label.Init before setting up the rest of the container, tells the library that
SELinux is enabled and everything works fine.

If a system is configured for SELinux but does not know about docker or
containers, then we want the transitions of the policy to work. Hard coding
the labels causes docker to break on older Fedora and RHEL systems

Such nodes could already be created by importing a tarball to a container; now
they can be created from within the container itself.
This gives non-privileged containers the mknod kernel capability, and modifies
their cgroup settings to allow creation of *any* node, not just whitelisted
ones. Use of such nodes is still controlled by the existing cgroup whitelist.

This implements cgroup.Apply() using the systemd apis.
We create a transient unit called "docker-$id.scope" that contains
the container processes. We also have a way to set unit specific
properties, currently only defining the Slice to put the
scope in.

This is a conversion of sd_booted() from libsystemd to go and checks
if the system was booted with systemd.

cgroups.procs moves all the threads of the process, and "tasks" just
the one thread. I believe there is a risk that we move the main thread,
but then we accidentally fork off one of the other threads if the go
scheduler randomly switched to another thread. So, it seems safer (and
more correct) to use cgroups.procs.

This leaves only the generic cgroup helper functions in cgroups.go and
will allow easy implementations of other cgroup managers.
This also wires up the call to Cleanup the cgroup which was missing
before.
