xshared: Share print_header() with legacy iptables
Legacy iptables fetches the relevant data via libiptc before calling the
shared routine which merely prints data as requested.
Drop the 'basechain' parameter, instead make sure a policy name is
passed only with base chains. Since the function is not shared with
ebtables (which uses a very rudimental header instead), this is safe.
In order to support legacy iptables' checking of iptc_get_references()
return code (printing an error message instead of the reference count),
make refs parameter signed and print the error message if it's negative.
