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().
