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.

- remove some annoying space in "summary-address" and "tag"

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
O 1:1::1/128 [110/20] via fe80::1833:c9ff:fe7b:3e43, r1-r2-eth0, weight 1, 00:00:49
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,
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, 00:00:39
O 1:1::1/128 [110/20] via fe80::1833:c9ff:fe7b:3e43, r1-r2-eth0, weight 1, 00:01:16
However the distance is not applied as there are no changes in the routing table
This commit will force the update of the routing table with the new configured distance
r1# sh ipv6 route

Replace custom implementation or call to ipaddr_isset with a call to
ipaddr_is_zero.
ipaddr_isset is not fully correct, because it's fine to have some
non-zero bytes at the end of the struct in case of IPv4 and the function
doesn't allow that.

Before this patch, if the first server crashed or was terminated, RPKI
connection keeps _active_ forever.
With this patch, if we catch connection problem (FATAL), we reset RPKI, to
switch to another available RTR-Server by using configured preference.
