If we meet a link we cannot dump we call plugin to check whether it's the link, that should be treated as external. Note, that on restore we don't call any plugins, but consider the setup-namespace script to move the respective link into the namespace. Links are not hierarchical and can be moved between namespaces easily, so it's OK to delegate the link creation to the script. Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
