When bs time out occurs,
1. Delete the bsm list
2. Reset the BSR address
3. delete nexthop tracking for the expired BSR
4. Give one more lease of life to all the bsr advertised rp with hold time
5. clear partial list of each grp node if not empty

DS Overview:
Bootstrap RP table has grp node.
scope --> rp table --> grp node1 --> rp list --> rp nodes(g2rp timer)
|
-------> grp node2 --> rp list --> rp nodes(g2rp timer)
When grp2rp mapping expires, following has to be done.
1. delete the rp node from the active bs-rp list in the list
2. calculate the elapsed time for other rp nodes in the list
3. delete those nodes having more elapse time than their hold time
4. If the list is not empty and current rp src is not static
rp change with new rp(head) & start g2rp timer with value holdtime - elapse
5. If the list is empty and current rp src for the grp is not static
delete the rp
6. If the list is not empty and current rp is static, just start the
g2rp timer with value holdtime - elapse
7. If list is empty and pending list is empty, delete grp node.
Note: g2rp timer will be run only on elected RP node for optimization.
when it expires, other node are update with elapse time.
This list is sorted insuch way that elected RP is the HEAD of list

1. listnode_add_sort_nodup - This API adds to list only if no duplicate
element available in the list. returns true/false
2. list_filter_out_nodes - This API deletes the nodes which satisfy the given
condition. condition is passed as a func ptr in
API. This function takes in node data(void ptr).

For each BSM packet, rpf check is performed. We will be accepting if the
source address match any of the next hop neighbor(in ecmp case) to reach
the Bootstrap Router.
1. pim_nexthop_match - this lookup in zebra and return true if any of the
next hop nbr is matching (in ecmp case).
2. pim_nexthop_match_nht_cache - this api searches the given address in local
pnc and return true if any of the next hop
nbr is matching (in ecmp case).

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.
