bgpd: Replace refcount with list of ifp names
Track the refcount a bit differently as that it is possible
to get into situations where we have multiple calls for the
same ifc. So let's just keep a list of the ifc's off of
each `struct bgp_addr` and then keep the hash entry based
upon list count or not.

The `struct bgp_addr` is not needed for anything other than

zebra: Send correct default vrf tableid for MROUTE stats
So the linux kernel uses the RT_TABLE_MAIN for the table
id used for ip routing. The multicast routing tables use
RT_TABLE_DEFAULT. We changed the internal code of zebra_vrf
a few months back to use RT_TABLE_MAIN as the tableid to
use. This caused the pim sg stats to stop working because
of the kernel bug where it uses a different table
for ip routing and ip multicast.
Put a bit of a special case in to do the right thing.

Newer linux kernels apparently send data down the netlink

place to do this is in the pim socket in pimd.
