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
