Add support for VRRP unicast

This patch adds the ability to use VRRP over unicast. Unicast IP
addresses may be specified for each VRRP instance with the 'unicast'
option. When a VRRP instance has one or more unicast IP address defined,
VRRP advertisements will be sent to each of those addresses. Unicast IP
addresses may be either IPv4 or IPv6.
