This patchset addresses Alexei's comment for commit "Handle SIGINT
when creating netns" [1]. Export local helpers create_netns() and
cleanup_netns() defined in mptcp.c into network_helpers.c as generic
ones. For this another helper unshare_netns() is added to replace
the existing local helpers create_netns().
