Subject: T4809: radvd: Allow the use of AdvRASrcAddress
This add the AdvRASrcAddress configuration option to configure
a source address for the router advertisements. The source
address still must be configured on the system. This is useful
for VRRP setups where you want fe80::1 on the VRRP interface
for cleaner VRRP failovers.
