Substitute ypset for ypbind in REQUIRE lines. If you use ypset it has to
happen right after ypbind, and before anything that uses NIS. The only
change in rcorder accomplished by this patch is make that happen.

As previously discussed, add the svn:executable property to all scripts

Remove the requirement for the FreeBSD keyword as it no longer
makes any sense.

Move the task of updating nsswitch.conf / host.conf into a separate
script called nsswitch.

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
