Add epair(4) support in $cloned_interfaces. One should be specified
as "epair0" in $cloned_interfaces and "epair0[ab]" in the others in
rc.conf like the following:
cloned_interfaces="epair0"
ifconfig_epair0a="inet 192.168.1.1/24"
ifconfig_epair0b="inet 192.168.2.1/24"
/etc/rc.d/netif now accepts both "netif start epair0" and "netif start
epair0a".
