Problem Statement:
=================
PIM Logs are coming at interval of 1 minute although pim
is not enabled.
Root Cause Analysis:
====================
By default, RCPM configures the PIM debugs when router comes up
via script. The product cannot disable PIM even though it is not required.
Hence moving these logs under a new debug option which will not be
enabled by default.
Fix:

VRF creation can happen from either cli or from
knowledged about the vrf learned from zebra.
In the case where we learn about the vrf from
the cli, the vrf id is UNKNOWN. Upon actual
creation of the vrf, lib/vrf.c touches up the vrf_id
and calls pim_vrf_enable to turn it on properly.
At this point in time we have a pim->vrf_id of
UNKNOWN and the vrf->vrf_id of the right value.
There is no point in duplicating this data. So just
remove all pim->vrf_id and use the vrf->vrf_id instead
since we keep a copy of the pim->vrf pointer.
This will remove some crashes where we expect the
pim->vrf_id to be usable and it's not.

Issue: Client1------LHR-----(int-1)RP(int-2)------client2
Client2 send IGMP join for group G.
Client1 send IGMP join for group G.
verify show ip mroute in RP, will have 2 OIL.
Client2 send IGMP leave.
Verify show ip mroute in RP, will still have 2.
Root cause: When RP receives IGMP join from client2, it creates
a (s,g) channel oil and add the interface int-2 into oil list and
set the flag PIM_OIF_FLAG_PROTO_IGMP to int-2
Client1 send IGMP join, LHR will send a (*,G) join to RP. RP will
add the interface int-1 into the oil list of (s,g) channel_oil and
will set the flag PIM_OIF_FLAG_PROTO_IGMP and PIM_OIF_FLAG_PROTO_PIM
to the int-1 and set PIM_OIF_FLAG_PROTO_PIM to int-2 as well. It is
happening because of the pim_upstream_inherited_olist_decide() and
forward_on() get all the oil and update the flag wrongly.
So now when client 2 sends IGMP prune, RP will not remove the int-2
from oil list since both PIM_OIF_FLAG_PROTO_PIM & PIM_OIF_FLAG_PROTO_IGMP
are set, it just unset the flag PIM_OIF_FLAG_PROTO_IGMP.
Fix: Introduced new flags in if_channel, PIM_IF_FLAG_MASK_PROTO_PIM
& PIM_IF_FLAG_MASK_PROTO_IGMP. If a if_channel is created because of
pim join or pim (s,g,rpt) prune received, then set the flag
PIM_IF_FLAG_MASK_PROTO_PIM. If a if_channel is created becuase of IGMP
join received, then set the flag PIM_IF_FLAG_MASK_PROTO_IGMP.
When an interface needs to be added into the oil list check if
PIM_IF_FLAG_MASK_PROTO_PIM or PIM_IF_FLAG_MASK_PROTO_IGMP is set, then
update oil flag accordingly.

RCA: When configured more than 32(MAXVIS), the inerfaces that are configured
after 32nd interfaces have the value of MAXVIF.
This is used as index to access the free vif tracker of array size 32(MAXVIFS).
So the channel oil list pointer which is present as the next field in pim structure get corrupt, when updating free vif.
This gets accessed during rpf update resulting in crash.
Fix: Refrain from allocating mcast interface structure and throw config error when more than MAXVIFS are attempted to configure.
Max vif checks are exempted for vrf device and pimreg as vrf device will be the first interface and not expected to fail and pimreg has reserved vif.

The memory type PIM_SPT_PLIST_NAME is specific to
SPT but we are going to store more prefix-list names
in pim, make it generic to allow for less confusion
in the future.

Issue 1:
1. Enable pim on an interface.
2. Configure query-interval or query max response time,
which results in pimd crash.
Root cause:
1. When pim is enabled on an interface, it creates a igmp socket
with querier_timer and other_querier time as NULL.
2. When query-interval/max_response_time is configured, it call the
function igmp_sock_query_reschedule() to reshedule the query. This
function check either of querier_timer or other_querier timer should
be running. Since in this case both are NULL, it results in crash.
Issue 2:
1. Enable pim on an interface.
2. Execute no ip igmp query-interval or query max response time,
which results in pimd crash.
Root cause:
1. When pim is enabled on an interface, it creates a pim interface
with querier_timer and other_querier time as NULL.
2. When no ip igmp query-interval/max_response_time is executed, it will
check either of querier_timer or other_querier timer should be running.
Since in this case both are NULL, it results in crash.
Fix:
When pim is enabled on an interface, it creates a igmp socket with
mtrace_only as true. So add a check if mtrace_only is true, then don't
reshedule the query.
