pim controls the vrf table creation for due to the way that
pim must interact with the kernel. In order to match the
table_id for unicast <-> multicast( not necessary but a
real nice to have ) we need to pass up from zebra the
table_id associated with the vrf.

The 'struct rib' data structure is missnamed. It really
is a 'struct route_entry' as part of the 'struct route_node'.
We have 1 'struct route_entry' per route src. As such
1 route node can have multiple route entries if multiple
protocols attempt to install the same route.

All PIM Neighbors for a given pim interface is registered with
BFD.
Upon receiving BFD status down event, PIM Neighbor with BFD info is deleted.
Add pim bfd configuraiton (CLI) per interface, '[no] ip pim bfd'
Testing Done:
Configure BFD under PIM interface on all neighbor routers,
check bfd sessions up, remote end unconfigure BFD, results in BFD session down.
Previous state was UP to New state DOWN, results in PIM neighbor delete behind
that particular pim interface.

Problem reported was that with some overlapping static route configurations,
when the link went down the less specific static was not re-installed after
the link came back up. Determined that with the overlapping statics, we
would recursively resolve the next-hop temporarily thru the more specific
static route, but since the next-hop wasn't actually reachable, we would go
through the code that clears the nht information for the static completely.
This caused the nht code to no longer process the static route.
After reviewing the process, there doesn't seem to be any reason that the
static should be deregistered in that section of code. Removed the
deregister and the problem is resolved and not addional failures seen in
manual testing. zebra_test.py completed successfully and ospf and bgp smokes
completed with no new failures.

Encountered a crash in zebra due to getting a delete on an SVI with
VRR configured. Since we don't actually do a delete but flag the interface
as inactive, slag VRR interfaces would remain on the vrf_iflist with a lock
count of zero, causing the crash. Since all other interface types are moved
to the default table before deleting, doing the same thing for any interfaces
that were left in the vrf.
Testing includes manual testing, bgp-min, ospf-min, vrf-min, bgp-smoke, and ospf-smoke.
All passed (first time or on rerun) or match known failures.

We only needed to add/change the vrf callbacks when we initialize
the vrf subsystem. As such it is not necessary to handle the callbacks
in any other way than through the init function.
