sqlite3: Implement eDBregister_vpnclientaddr()

This commit implements the eDBregister_vpnclientaddr() needed by the
newer eurephia-auth plug-in.  This is needed to improve the tun support
in eurephia.

In addition, this also updates the SQL schema to include IPv4 and in
the future IPv6 addresses in the lastlog and VPN address history
(openvpn_vpnaddr_history).  The old openvpn_macaddr_history table
is deprecated.
