Current code treats all metaqueues as lists of route_node structures.
However, some queues contain other structures that need to be cleaned up
differently. Casting the elements of those queues to struct route_node
and dereferencing them leads to a crash. The crash may be seen when
executing bgp_multi_vrf_topo2.
Fix the code by using the proper list element types.

FRR stores the route_tag in network byte order. Bug filed indicates
that the `show ip ospf route` command shows the correct value.
Every place route_tag is dumped in ospf_vty.c the ntohl function
is used first.

RA packets are pretty chatty and when there is a warning from
a missconfiguration on the network, the log file gets filed
up with warnings. Modify the code in rtadv.c to only spit
out the warning in these cases at most every 6 hours.

if r1 has a route received from a neighbor and the same route
configured as static, the administrative distance will determine
which route to use
r1(config)# ipv6 route 1:1::1/128 Null0 70
r1# sh ipv6 route
Codes: K - kernel route, C - connected, S - static, R - RIPng,
O - OSPFv3, I - IS-IS, B - BGP, N - NHRP, T - Table,
v - VNC, V - VNC-Direct, A - Babel, F - PBR,
f - OpenFabric,
> - selected route, * - FIB route, q - queued, r - rejected, b - backup
t - trapped, o - offload failure
S>* 1:1::1/128 [70/0] unreachable (blackhole), weight 1, 00:00:12

The static route is selected. If we now change the administrative distance
in ospf6, the OSPF route should be selected
r1(config)# router ospf6
r1(config-ospf6)# distance 50
r1# sh ipv6 route
Codes: K - kernel route, C - connected, S - static, R - RIPng,

However the distance is not applied as there are no changes in the routing table
