Implemented multi-address DNS expansion on the network field of route
commands. When only a single IP address is desired from a multi-address DNS expansion, use the first address rather than a random selection. Version 2.1.1l git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@6291 e7ae566f-a301-0410-adde-c780ea21d3b5
