PIM support for VPNs

To support PIM for VPNs, a multicast router that runs PIM maintains an independent set of PIM neighbor
table, multicast routing table, BSR information and RP-set information for each instance.
After receiving a multicast packet, the multicast router checks which VPN the packet belongs to, and then
forwards the packet according to the multicast routing table of that VPN or creates a multicast routing
table entry for that VPN.
