This patch adds a nsproxy structure to the task struct. Later
patches will move the fs namespace pointer into this structure,
and introduce a new utsname namespace into the nsproxy.
The vserver and openvz functionality, then, would be implemented
in large part by virtualizing/isolating more and more resources
into namespaces, each contained in the nsproxy.
