ospf6d: fix ospf6 crash in inp lsa processing
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.

lib, zebra: Allow the specification of BUM flooding
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

If flooding is disabled then BUM traffic will not be forwarded

1. "show bgp ipv4 json"
- Added "network" field which displays a prefix in 'prefix/prefixlen' format.

- JSON does not have "prefix", "prefixLen" fields which are present in IPv4

bgpd: Incorrect sent prefix count for a split subgroup
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.

bgpd: Convert `struct bgp_info` to `struct bgp_path_info`
Do a straight conversion of `struct bgp_info` to `struct bgp_path_info`.
This commit will setup the rename of variables as well.
This is being done because `struct bgp_info` is not descriptive
of what this data actually is. It is path information for routes
that we keep to build the actual routes nexthops plus some extra
information.

doc: correct route map match for prefix lists
This corrects the route map documentation to add the missing "prefix-list"
keyword, which is necessary when matching against a prefix list (as opposed to
an access list).
Additionally, change hyphens for underscores in the variables the user is
supposed to substitute in those commands, to prevent any confusion with the
"prefix-list" keyword itself, and also to make it more consistent with the
other documented commands (which are already using underscores).

While testing 5549 support using global addresses, discovered that
ipv6 nexthop tracking thru a route-reflector didn't work. Since
the next-hop used for remote nexthops resolves to the link-local

interface down events. Also tripped over a crash in certain cases
which is also resolved in this fix.

The condition in the do/while is always false because 'return_nsid' cannot
reach the end of the loop with 'return_nsid' having a different value than
NS_UNKNOWN. Because of that, the condition can be replaced with 0 (false).
Also, the loop can be removed because the two assignments made at the end
of the loop before the condition check are not used (detected via Clang,
afterwards).

watchfrr, lib: cleanup & delay detaching
This cleans up watchfrr to be more "normal" like the other daemons in
terms of what it does in main(), i.e. using the full frr_*() call set.
Also, this changes the startup behaviour on watchfrr to stay attached on
the daemon's parent process until startup is really complete. This
should allow removing the "watchfrr.started" hack at some point.
