After restarting pim6d, in some cases the ifindex is 0 for the interfaces,
so the vif index is also assigned as 0.
This causes the interface name to be pim6reg.
Fix:
If the ifindex is 0 and the interface name is not "pimreg" or "pim6reg",
the function will return without assigning vifindex with an error message.

If the pimreg device exists but it has not been set to the pim->pimreg pointer we can have
a crash. Just prevent the crash since it's some sort of startup / re-org the network
issue.

Changing
IGMP_DEFAULT_ROBUSTNESS_VARIABLE to GM_DEFAULT_ROBUSTNESS_VARIABLE,
IGMP_GENERAL_QUERY_INTERVAL to GM_GENERAL_QUERY_INTERVAL,
IGMP_QUERY_MAX_RESPONSE_TIME_DSEC to GM_QUERY_MAX_RESPONSE_TIME_DSEC and
IGMP_SPECIFIC_QUERY_MAX_RESPONSE_TIME_DSEC to GM_SPECIFIC_QUERY_MAX_RESPONSE_TIME_DSEC
to accomodate both igmp and mld. And moved it to common file.

After restart pim dr address was zero due to which pim (*,G) join
could not get propagated towards RP.
While trying to find primary address ll_highest will be zero initially,
since we have not received address from zebra yet.
So we can get the best address at this point and use it as primary address
whenever ll_highest is zero.

Deletion of pim interface(pim_if_delete) should
do the below things before cleanup.
1. Send a hello message with zero hold time.
2. Delete all the neighbors.
3. Close the pim socket.

Fresh ground-up MLD implementation with subscriber-tracking for MLDv2.
Intended to be adapted for IPv4 and replace the IGMP implementation at a
later point.
Tested in ANVL, currently at 94/116. Some issues/TODOs are left in the
code as CPP_NOTICE markers, but the code is very much good enough to
proceed since otherwise we're blocked on overall PIM v6 progress.

I should've removed this in #10960. It's a hazard in terms of
forgetting to adjust PRs/other changes that might accidentally still
reference the field.

The only function these macros have is to make the code confusing.
"PIM_IF_DO_PIM" sounds like it triggers some action, but it doesn't.
Replace with "bool" fields in struct pim_interface.
(Note: PIM_IF_*_IGMP_LISTEN_ALLROUTERS was always set, without any way
to unset it. It is completely removed now and always enabled.)

We only care about link-local addresses for IPv6 operation. Also, MLD

These really don't serve much of a purpose, especially with how
