xtables: Introduce and use common function to parse val[/mask] arguments
There are a couple of places in both core and extensions where arguments
in the form of val[/mask] is parsed (see XTTYPE_MARKMASK32).
In some cases symbolic name might be used which is mapped in code to
numeric value.
Introduce common function to handle both cases where value given is
either val[/mask] or symbolic name.
