Michael Crosby 5f4bc4f916 Use apparmor_parser directly
The current load script does alot of things.  If it does not find the
parser loaded on the system it will just exit 0 and not load the
profile.  We think it should fail loudly if it cannot load the profile
and apparmor is enabled on the system.

Kato Kazuyoshi c5226d94fa Avoid "invalid memory address or nil pointer dereference" panic
libcontainer.GetNamespace returns nil on FreeBSD because
libcontainer.namespaceList is empty. In this case, Namespaces#Get should
return nil instead of being panic.

Alexander Larsson 59c1b2880b Fix libcontainer network support on rhel6
It seems that netlink in older kernels, including RHEL6, does not
support RTM_SETLINK with IFLA_MASTER. It just silently ignores it, reporting
no error, causing netlink.NetworkSetMaster() to not do anything yet
return no error.

We fix this by introducing and using AddToBridge() in a very similar manner
to CreateBridge(), which use the old ioctls directly.

This fixes https://github.com/dotcloud/docker/issues/4668

Dan Walsh 2224e0d65a In certain cases, setting the process label will not happen.
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.

Alexander Larsson 7f7d8419a7 cgroups: Splity out Apply/Cleanup to separate file/interface
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.

Dan Walsh 4c43566925 This patch adds SELinux labeling support.
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.
