So when we remove a ifchannel from the system we should check to
see if we still care about the S,G having it in the OIL still
due to inheritance rules. The deletion does not necessarily
mean it should not be in the OIL for the S,G.

Prevent IPv6 routes received via a ibgp session with one of its own interface
ip as nexthop from getting installed in the BGP table.
Implemented IPV6 HASH table, where we need to add any ipv6 address as they
gets configured and delete them from the HASH table as the ipv6 addresses
get unconfigured. The above hash table is used to verify if any route learned
via BGP has nexthop which is equal to one of its its connected ipv6 interface.

the json code has not been updated since a variety of new flags have
been added to the code base. Add those flags in so we can tell
what is going on sometimes.

Add the ability to select on a S or G for a `show ip mroute`
command.

Always when creating a new S,G state look at all possible ifchannels
to decide what the mroute should be.
The bug that this is fixing is this:
Suppose two incoming `*,G` joins on swp1, and swp2.
Now suppose that one of those ifchannel `*,G` sends a `*,G S,G RPT Prune`.
We were creating the S,G upstream state as we should but we were
only looking at the S,G ifchannel to decide the S,G mroute we would
be creating. As such what we need to do is to look over the associated
*,G ifchannels and allow us to associate correct oil needed.

Fixup in response to Jafar's review comments.
This is actually old code moved in from pimd to lib. But the fixup does
make sense.

1. vxlan instance cleanup needs to be done before the upstream entries are
force-flushed.
2. also vxlan callbacks need to be ignored post instance-cleanup.

The l2vni (bgpevpn instance) was maintaining a back pointer to the
tenant vrf without locking it. This would result in bgp_terminate crashing
as the tenant-vrf is released before the underlay-vrf (vpn->bgp_vrf->l2vnis
is NULL). Call stack -
