Added --allow-pull-fqdn option which allows client to pull DNS names
from server (rather than only IP address) for --ifconfig, --route, and --route-gateway. OpenVPN versions 2.1_rc7 and earlier allowed DNS names for these options to be pulled and translated to IP addresses by default. Now --allow-pull-fqdn will be explicitly required on the client to enable DNS-name-to-IP-address translation of pulled options. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3307 e7ae566f-a301-0410-adde-c780ea21d3b5
