netifd: Request DHCP option 121 (classless route) by default
This option, defined by RFC3442, allows a DHCP server to send static routes to a client. But the client has to request this option explicitely. Static routes are useful when the gateway configured by DHCP cannot be in the same subnet as the client. This happens, for instance, when using DHCP to hand out addresses in /32 subnets. A new configuration option "classlessroute" is available, allowing users to disable this feature (the option defaults to true). Other DHCP clients already request this option by default (dhcpcd, for instance, and possibly Windows). If a DHCP server does not support this option, it will simply ignore it.
