pbrd: Set next/prev to NULL on cached nexthops
When we copy a new nexthop to cache and track, set its
next and prev pointers to NULL. We don't want those since
this is to be treated as a single nexthop.Other nexthops that
aren't in a group could hash to this nexthop so it doesn't
make sense to keep those pointers in the cache.

bgpd: add l2vpn evpn to afi safi parse utility
Problem reported with "clear bgp l2vpn evpn * soft" clearing the
wrong afi/safi (cleared ipv6 unicast instead). Determined that
the calling function used the argv_find_and_parse_afi/safi routines
to determine the correct afi/safi to pass on. Since l2vpn/evpn were
missing from the lookup, the command defaulted to ipv6 unicast. This
fix just adds that afi/safi to the lookup routine.

bgpd: Filtering received EVPN routes based on VNI does not work
Issue1: When "neighbor X.X.X.X route-map RM-VNI-FILTER in" is configured under evpn address-family,
all the received routes are dropped regardless of whether the route has a matching vni or not.
Issue2: Routes with 2 labels are not filtered correctly
Issue3: Interpreting the label based on tunnel type, vxlan was not done correctly.
Vxlan label has 24 bits, whereas, MPLS label is 20 bits long
Fix1: The handler bgp_update() that services the received route ignored the route's label while deciding whether to filter it or not. As part of the fix, the handler now uses the label info to make the decision about whether to filter the route or not.
Fix2: route_match_vni() now tries to match both the labels within the route, not just the one.

dynamically take effect.

the route-maps dependent on it, has been introduced to address this issue.
