Centralize the n-flag-clear processing to a single point.
Signed-off-by: Fredi Raspall <fredi@voltanet.io>

If the n-flag-clear option is set in the configuration of a prefix
segment, clear the flag in the extended ip reachability TLVs.
RFCs 7794 and 8667 are not too strict on the setting / clearing the
N-flag in prefix SIDs. However, if there exists a cmd line option
to clear it, it should be cleared in the TLVs announced, as other
vendors do.

RIPNG schedules a call to `ripng_interface_wakeup` in 1 second after
receiving the interface UP event from zebra. The function is called even
if the interface was shut down during this interval.
This is incorrect and also leads to a crash in the following scenario:
```
vtysh -c "conf" -c "router ripng vrf red" -c "network enp2s0"
ip link add red type vrf table 1
ip link set enp2s0 vrf red
ip link set enp2s0 down
ip link set enp2s0 up && sleep 2 && ip link del red
```

Track 'down' state of connected addresses with a new flag. We
may have multiple addresses on an interface that share a prefix;
in those cases, we need to determine when the first address
is valid, to install a connected route, and similarly detect
when the last address goes 'down', to remove the connected
route.

if_netlink.c created it's on nested parsing #define which
is identical to netlink_parse_rtattr_nested. Consolidate
on one instead of having this duality.

In order to parse the netlink message into the
`struct rtattr *tb[size]` it is assumed that the buffer is
memset to 0 before the parsing. As such if you attempt
to read a value that was not returned in the message
you will not crash when you test for it.
The code has places were we memset it and places where we don't.
This *will* lead to crashes when the kernel changes. In
our parsing routines let's have them memset instead of having
to remember to do it pre pass in to the parser.

Deconfiguring conditional advertisement resulted in all other policy
settings on the peer getting removed due to an excessively large memset.
This also created a desync with the northbound config tree, which caused
its own set of problems...
Fix the memset to just remove the conditional advertisement config.

The code had no limits on addresses configured on an interface running
ospf6d. The code would crash when more than 100 addresses were added.
This change limits the number of interface address to 100 if mtu is set
to the default value. If the mtu is set to a jumbo packet size or larger
we will support 200 interface addresses.

Fixes OSPFv3-26.13 ANVL RFC conformance bug #8576 by improving the bugfix
for #7030 from 4c63a76a. That commit changed handling of received old
non-MAXAGE LSAs with a MAXAGE counterpart in the LSDB from "add all LSAs to
LSDB and flood non-self-originated ones" to "add & flood only
non-self-originated LSAs and ignore self-originated LSAs". The new behaviour
is similar but adds sending a MAXAGE LS Update for received self-originated
LSAs to remove the old LSAs from the network, resulting in "add & flood
non-self-originated LSAs, don't add but send MAXAGE LS Update for
self-originated LSAs". The missing MAXAGE LS Update is what OSPFv3-26.13
ANVL complained about.

For EVPN routes, there is specific logic in place for path selection
surrounding MAC Mobility. For pure type-5 routes, if a route is
advertised with a MED, this is ignored since it ultimately falls inside
of the EVPN specific path selection logic, and ultimately selects the
lower IP address. This change ensures only type-2 routes fall into the
EVPN BGP path selection.

When clagd is stopped on secondary device,
all vxlan interfaces (vnis) are kept in protodown state.
FRR treats protodown vxlan interfaces (vnis) as interface down
and sends vni delete to bgpd.
In the event of clagd down, SVIs are flapping as underlying
bridge is going through churn.
When FRR receives SVI up notification do not trigger event to bgpd
if vnis are operationaly down.
Ticket:#2600210 CM-22929
Reviewed By:CCR-11544
Testing Done:
Performed CLAG stop/start on secondary device, all vxlan devices
remained in protodown along with this validated the vnis are cleaned up
and added back in bgpd.
