Change the default value of synchronous_dhclient to NO.

To preserve the existing behavior of etc/rc.d/netif, add code to wait
up to if_up_delay seconds (30 seconds by default) for a default route to
be configured if there are any dhcp interfaces.  This should be extended
to test that the interface is actually up.
