Modifying the code as per RFC 4604 section 2.2.1
EXCLUDE mode does not apply to SSM addresses, and an SSM-aware router
will ignore MODE_IS_EXCLUDE and CHANGE_TO_EXCLUDE_MODE requests in
the SSM range.
Issue is observed when a group in exclude mode was in ASM range
as per the prefix-list and then prefix-list is modified to make
it fall under SSM range. The (*,G) entry remains there.
So when the group moves to ssm range and it is exclude mode,
delete the group from the IGMP table.

show ip mroute json command displays the source, group info
per oil, so for pruned group since the OIL is empty, it is not
showing.
Fix: Added the above information per source.

Now we return all zeroed stats, which seems wrong. Handle the same way, as
with PIM interfaces. Return empty JSON and a warning for VTYSH.
```
exit1-debian-11# sh ip igmp statistics interface belekas
% No such interface
exit1-debian-11# sh ip igmp statistics interface belekas json

The current code in pim_register_stop_recv would never fail as
that the code was always returning 0 in all cases, but
if the code parses an incorrect afi then it has failed and
should return as much

RCA: (*,G) register stop was not handled
Fix: Loop through all (S,G) under the (*,G) and apply reg stop

We only care about link-local addresses for IPv6 operation. Also, MLD
needs the lowest while PIM needs the highest...

Try to untangle some spaghetti...
This is an 1:1 change that should not result in any functional
difference.

These will corrupt memory if mroute_vif_index is -1 (e.g. interface not
operating.) That shouldn't happen, but it does while doing development
work, so trip an assert rather than corrupting memory.

Currently the nexthop tracking code is only sending to the requestor
what it was requested to match against. When the nexthop tracking
code was simplified to not need an import check and a nexthop check
in b8210849b8 for bgpd. It was not
noticed that a longer prefix could match but it would be seen
as a match because FRR was not sending up both the resolved
route prefix and the route FRR was asked to match against.
This code change causes the nexthop tracking code to pass
back up the matched requested route (so that the calling
protocol can figure out which one it is being told about )
as well as the actual prefix that was matched to.

sockopt_cork is a no-op function that was cleaned up
in 2017. Since then it's still not being used. At
this point in time there is little point in keeping a
dead function that will not be used because of vagaries
between platforms

This isn't a system or interface setting, it's a socket behavior. It is
both irrelevant and confusing to the user since it doesn't affect any
system behavior (but it sounds like it does). Whether it is enabled or
not is solely relevant to how the code is designed to work.
So, remove it from output.
