NetworkManager/src/nm-ip6-config.c
Thomas Haller 936ebdc724 core: consistently use _nm_ip_config_add_obj() when adding route/address to ip-config 
_nm_ip_config_add_obj() does some additional checking, like setting the ifindex.
We shall not bypass this also during bulk-update (replace).

Add options @merge and @append_force to make _nm_ip_config_add_obj() suitable
in those cases too, and use it.
