cgroup: notify ns_cgroup deprecated
The ns_cgroup will be removed very soon. Let's warn, for this version, ns_cgroup is deprecated. Make ns_cgroup and clone_children exclusive. If the clone_children is set and the ns_cgroup is mounted, let's fail with EINVAL when the ns_cgroup subsys is created (a printk will help the user to understand why the creation fails). Update the feature remove schedule file with the deprecated ns_cgroup.

+What: namespace cgroup (ns_cgroup)
+When: 2.6.38
+Why: The ns_cgroup leads to some problems:
+ * cgroup creation is out-of-control
+ * cgroup name can conflict when pids are looping
+ * it is not possible to have a single process handling
+ a lot of namespaces without falling in a exponential creation time
+ * we may want to create a namespace without creating a cgroup
+
+ The ns_cgroup is replaced by a compatibility flag 'clone_children',
+ where a newly created cgroup will copy the parent cgroup values.
+ The userspace has to manually create a cgroup and add a task to
+ the 'tasks' file.
