Introduce the ability to create new cgroup namespace. The newly created
cgroup namespace remembers the cgroup of the process at the point
of creation of the cgroup namespace (referred as cgroupns-root).
The main purpose of cgroup namespace is to virtualize the contents
of /proc/self/cgroup file. Pr
e minds I can update it too.
Changelog 20151223:
- don't allocate memory pr_cont_kernfs_path() under spinlock

I'd very appreciate some feedback on this (and following) patch from DT
camp, so I could incorporate them in the next attempt after merge window
closed.
