This patch partially isolates ipv4 by adding the network namespace
structure in the structure sock, bind bucket and skbuf. When a socket
is created, the pointer to the network namespace is stored in the

This patch adds to the nsproxy the network namespace and a set of
functions to unshare it. The network namespace structure should be
filled later with the identified network ressources needed for more
