fixes the recent support bmp monitor of VPNv4 afi/safi
the bmp updates messages (MP_REACH_NLRI) are never sent for VPNv4 and bmp withdraws (MP_UNREACH_NRLI) are sent instead
this is caused by bgp_node_lookup which fails to find VPNv4 bgp_node in the rib which results in NULL path info attributes passed to bmp_monitor
using bgp_afi_node_lookup instead of bgp_node_lookup solves the problem

Topology:
R1(LHR) ---- R2 ----R4(FHR)
---- R3 ----
R2 = RP
Steps to reproduce:
1. R1(LHR) sends IGMP join, R4(FHR) sends multicast traffic.
Verify traffic is flowing from FHR to LHR.
2. Restart R1(LHR).
3. Below sequence of events are happening after FRR restart in R1(LHR).
4. R1(LHR) Register RP address to Zebra.
5. R1(LHR) Receive update from Zebra that R2(RP) is reachable via R3.
6. R1(LHR) Receive IGMP join for group 225.1.1.1, will create pim upstream
and (*,G) mroute with IIF towards R3.
7. R1(LHR) Receive update from Zebra that RP is reachable via R2(RP).
8. R1(LHR) Update the PIM upstream IIF, but not updating the (*,G) IIF
even there is RPF change.
9. R1(LHR) receives IGMP join for group 225.1.1.2, will create (*,G) with
IIF towards R2(RP), both upstream and (,G) created with IIF towards R2(RP).
Root Cause:
Mroute IIF is not getting updated when better route update
received. It is still pointing to the older nexthop.
Fix:
Update the mroute IIF when there is change in nexthop.

In ospf_handle_exnl_lsa_lsId_chg there is a code path
where that we may be using uninitialized data for decisions.
Doubtful that this happens but let's make it less likely to
even more.

When using bgp_vty_afi_from_str it can
return AFI_MAX( but in practice never will with
our cli ). In bgp_default_afi_safi_cmd the code
directly references:
bgp->default_afi[afi][safi] = TRUE;
and if afi is AFI_MAX FRRR would be accessing
memory where it should not be.
Let's just provide some assurances for coverity
that this never happens.

Coverity is complaining that buf has not been initialized.
It has and coverity appears to be confused so let's help it
find the initialization.

Enhanced few exsiting PIM APIs to support both
IPv4 and IPv6 configuration. Added few new APIs
for PIMv6. Tested all existing tests with new
API changes.
