dual stack vlan-pcp support

Hi, 

A french FTTH ISP only accept DHCP requests vlan tagged with priority. While
this is implemented in FreeBSD-Base dhclient through option "vlan-pcp", it does
not support DHCPv6.
Waiting for DHCPv6 support to be added in base dhclient, I think it would be
nice to support vlan-pcp in isc-dhcpd44-client.

So I ported the IPv4 side from base to isc-dhcp44-client, and added IPv6
support through setsockopt(info->wfdesc, IPPROTO_IPV6, IPV6_VLAN_PCP, &pcp,
sizeof(pcp).
Please see patch attached.

Could this be added as a patch in, p.e., files/vlanpcp.patch ?

Thanks
