Recent changes to the nht code in bgp caused us to actually
keep a true count of v6 nexthop paths when using v4 over v6.
This change introduced a race condition on shutdown on who
got to the bnc cache first( the v4 table or not ). Effectively
we were allowing the continued existence of the path->nexthop
pointing to the freed bnc. This was especially true when
we had route leaking. So when we free the bnc make sure
we clean up the path->nexthop variables pointing at it too.

If you are using bgp unnumbered( or interface based peers )
when we detect an error give the user a bit more of a clue
what they may have done wrong.

isisd would crash when lsp fragments aged out, since they got freed
correctly, but were not removed from LSP0's linked list of fragments.

The evpn_vtep_ip_cmp function must return positive and negative
numbers for when we are doing sorted linked list inserts.
Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
The purpose of adding a l2vni as an sorted list is
shot in the foot when the l2vni compare function only
returns 0 or 1. This will cause subtle crashes when
we add sorted and we end up with multiple list node pointing
to the same thing.

Use ospf6_prefix_same for comparing two exact same prefix
to determine ECMP for a route.
ospf6_route_cmp expects two different prefix rather
being exactly same.
Ticket:CM-22630
Testing Done:
performed ECMP of intra network prefix route via
sending same route via different available
ospf6 paths.

Add the '[no] flood <disable|head-end-replication>' command
to the l2vpn evpn afi/safi sub commands for bgp. This command
when entered as 'flood disable' will turn off type 3 route
generation for the transmittal of the type 3 route necessary
for BUM replication on the remote VTEP. Additionally it will
turn off the BUM handling via the new zebra command,
ZEBRA_VXLAN_FLOOD_CONTROL.

Allow the modification of whether or not we will allow
BUM flooding on the vxlan bridge. To do this allow
the upper level protocol to specify via the ZEBRA_VXLAN_FLOOD_CONTROL
zapi message.
If flooding is disabled then BUM traffic will not be forwarded
to other VTEP's.

1. "show bgp ipv4 json"
- Added "network" field which displays a prefix in 'prefix/prefixlen' format.
2. "show bgp ipv6 json"
- Added "network" field which displays a prefix in 'prefix/prefixlen' format.
- JSON does not have "prefix", "prefixLen" fields which are present in IPv4
command. Added these fields as they are useful.
3. "show bgp ipv4/ipv6 neighbor <neighbor_addr> advertised-routes json"
- Added "network" field.
4. "show bgp ipv4/ipv6 summary json"
- Added "pfxSnt" for peers. This count is obtained from corresponding
update_subgroup.
5. "show bgp neighbor json"
- Added "sentPrefixCounter"

When reading in config files and we have failures on multiple
lines actually note the actual failure lines and return them.
This fixes an issue where we stopped counting errors after
the first one and we got missleading line numbers that
did not correspond to the actual problem.
This is fixed:

When executing vpn route-map config for importation, the running-config
records vrf import route-map instead. Actually, this is a problem when
restarting configuring when using vpn route-map. The choice is done to
move to vrf format, when at least one import list is created for vrfs.

When a subgroup splits to form a new subgroup because of policy changes
for a peer, new subgroup copies adj out(state about advertised routes)
from the parent subgroup. At the same time, it should also copy
scount(advertised prefix count) to the new subgroup for the count to be
in sync with the adj_out for the subgroup.
