This was found while doing libyang2 work (causes assert); however, it is
also incorrect for libyang1 (empty canonical value for incorrectly
referenced interface vs interface-name node).
While here, fix 2 other incorrect uses of "." on a container node.

When the control plane protocol is created, the vrf structure is
allocated, and its address is stored in the northbound node.
The vrf structure may later be deleted by the user, which will lead to
a stale pointer stored in this node.
Instead of this, allow daemons that use the vrf pointer to register the
dependency between the control plane protocol and vrf nodes. This will
guarantee that the nodes will always be created and deleted together, and
there won't be any stale pointers.
Add such registration to staticd and pimd.

On looking at bgp_bfd_dest_update the function call into bfd_get_peer_info
when it fails to lookup the ifindex ifp pointer just returns leaving
the dest and src prefix pointers pointing to whatever was passed in.
Let's do two things:
a) The src pointer was sometimes assumed to be passed in and sometimes not.
Forget that. Make it always be passed in
b) memset the src and dst pointers to be all zeros. Then when we look
at either of the pointers we are not making decisions based upon random
data in the pointers.

RCA: There were 2 problems.
1. SGRpt prune expiry didn't create S,G entry with none oil when no other
interfaces were part of the oil.
2. When restarting the timer with new hold value, comparision was missing and
old timer was not stopping.
Fix:
SGRpt Prune pending expiry will put SG entry with none oil if no other

interfaces present. If present we will be deleting the inherited oif from oil.
Deleting the oif in that scenario will take care of changing mroute.
When alone interface expires in SGRpt prune pending state, we shall detect by
checking installed flag. if not installed, install mroute.

1. When a node changes from non-DR to DR in the given topology,
the node was receiving both PIM Join as well as IGMP join.
Since it was already receiving PIM Join previously, ifchannel was
already present. Hence when it becomes DR, the IGMP source flag is not
set due to issue in the code. Hence it never creates S,G entry thinking
that it is not DR.
2. When pim join expires, the pim flag is not reset when ifchannel is not
deleted.
