pulled in via the <tunables/global> include.

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.

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.

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.

docker will run the process(es) within the container with an SELinux label and will label
all of the content within the container with mount label. Any temporary file systems
created within the container need to be mounted with the same mount label.
The user can override the process label by specifying
-Z With a string of space separated options.
-Z "user=unconfined_u role=unconfined_r type=unconfined_t level=s0"
Would cause the process label to run with unconfined_u:unconfined_r:unconfined_t:s0"
By default the processes will run execute within the container as svirt_lxc_net_t.
All of the content in the container as svirt_sandbox_file_t.
The process mcs level is based of the PID of the docker process that is creating the container.
If you run the container in --priv mode, the labeling will be disabled.

This also adds an enabled field to the types so that they

This moves the bind mounts like /.dockerinit, /etc/hostname, volumes,
etc into the container namespace, by setting them up using lxc.
This is useful to avoid littering the global namespace with a lot of
mounts that are internal to each container and are not generally
needed on the outside. In particular, it seems that having a lot of
mounts is problematic wrt scaling to a lot of containers on systems
where the root filesystem is mounted --rshared.
Note that the "private" option is only supported by the native driver, as
lxc doesn't support setting this. This is not a huge problem, but it does
mean that some mounts are unnecessarily shared inside the container if you're
using the lxc driver.

Use the DOCKER_RAMDISK env var to tell the native driver not to use
a pivot root when setting up the rootfs of a container.
