There has been quite a confusion in userspace about XT_FUNCTION_MAXNAMELEN; because struct xt_entry_match used MAX-1, userspace would have to do an awkward MAX-2 for maximum length checking (due to '\0'). This patch adds a new define that matches the definition of XT_TABLE_MAXNAMELEN - being the size of the actual struct member, not one off.
