Break out and rewrite the network setup scripts.
o /etc/network.subr contains common subroutines used for seting up network interfaces o rc.d/hostname sets the hostname if not already set o rc.d/nisdomain sets the nis domain *after* rpcbind but before the yp* daemons. This fixes issues with temporary hangs when looking up informaion in nis before it's ready. o rc.d/netif brings network interfaces (minus dhcp) up. o rc.d/network1 has been disabled and will be retired before RELENG_5. It will be replaced by rc.d/netif Approved by: markm (mentor)
