xtables: Introduce and use common function to print val[/mask] arguments
There are number of places where argument is in val[/mask] format printed in extensions and some of them may print corresponding symbolic name. By introducing common function for this task we eliminate custom code parts in extensions to perform printing of arguments in required formats. Use xtables_print_mark_mask() helper for extensions without symbolic name for val[/mask]. Signed-off-by: Serhey Popovych <serhe.popovych@gmail.com> Signed-off-by: Florian Westphal <fw@strlen.de>
