    ctdb-scripts: Call iptables/ip6tables directly from iptables_wrapper
    
    Drops the iptables() and ip6tables() functions and, hence, the
    hardcoding of paths /sbin/iptables and /sbin/ip6tables.  The latter
    avoids problems on openSUSE where (for example) /usr/sbin/iptables is
    used instead.
    
    This means that locking around ip*tables commands is only done when
    iptables_wrapper is called directly.  This is fine because the only
    conflict is when "releaseip" or "takeip"/"updateip" events are run in
    parallel.  The other uses in 11.natgw and 70.iscsi are in events where
    there will be no collisions.
    
    Making 11.natgw support IPv6 is unnecessary.  Just put a static IPv6
    address on each interface - they're plentiful.
