0fb22f3e9b topotests: update interface in SRv6 topotest
Previously, routes leaked from one VRF to another VRF were associated
with the original nexthop interface.

Due to this change, the `bgp_srv6l3vpn_route_leak` topotest always fails
because it still expects the nexthop interface.

This commit fixes the expected interface name in the
`bgp_srv6l3vpn_route_leak` topotest.

60e73903d5 topotests: update ospf_multi_vrf_bgp_route_leak
Leaked connected routes have now the following nexthop interfaces:
- lo for routes imported from the default VRF
- or the VRF interface for routes imported from the other VRFs.

db7cf73a33 bgpd: fix interface on leaks from redistribute connected
In the target VRF's Routing Information Base (RIB), routes that are
leaked and originate from the 'redistribute connected' command have
their next-hop interface set as the interface from the source VRF.
This prevents the IP address of the connected interface from being
reachable from the target VRF.

Extract from the routing table:
> VRF r1-cust1:
> C>* 172.16.29.0/24 is directly connected, r1-eth4, 00:44:15
> S>* 192.0.2.0/24 [1/0] is directly connected, r1-cust4 (vrf r1-cust4), weight 1, 00:00:30

In r1-cust4 VRF, the nexthop interface of 172.16.29.0/24 is r1-eth4,
which is unknown in the context. The following ping does not work:

> # tcpdump -lnni r1-cust1 'icmp' &
> # ip vrf exec r1-cust4 ping -c1 -I 192.0.2.1 172.16.29.1
> PING 172.16.29.1 (172.16.29.1) 56(84) bytes of data.
PING 172.16.29.1 (172.16.29.1) from 192.0.2.1 : 56(84) bytes of data.
18:49:20.635638 IP 192.0.2.1 > 172.16.29.1: ICMP echo request, id 15897, seq 1, length 64
18:49:27.113827 IP 192.0.2.1 > 192.0.2.1: ICMP host 172.16.29.1 unreachable, length 92

Fix the issue by setting nh_ifindex to the index of the VRF master
interface of the incoming BGP instance. The result is:

> VRF r1-cust4:
> C>* 192.0.2.0/24 is directly connected, r1-cust5, 00:27:40

067fbab4e4 bgpd: fix interface on leaks from network statement
Leaked routes from prefixes defined with 'network <prefix>' are inactive
because they have no valid nexthop interface.

>   import vpn
>  exit-address-family
> exit

Extract from the routing table:

> VRF r1-cust1:
> S>* 172.16.29.0/24 [1/0] via 192.168.1.2, r1-eth4, weight 1, 00:47:53
>
> VRF r1-cust4:
> B   172.16.29.0/24 [20/0] is directly connected, unknown (vrf r1-cust1) inactive, weight 1, 00:03:40

Routes imported through the "network" command, as opposed to those
redistributed from the routing table, do not associate with any specific
interface.

When leaking prefix from other VRFs, if the route was imported from the
network statement (ie. static sub-type), set nh_ifindex to the index of
the VRF master interface of the incoming BGP instance.

The result is:

> VRF r1-cust4:
> B>* 172.16.29.0/24 [20/0] is directly connected, r1-cust1 (vrf r1-cust1), weight 1, 00:00:08

dda5de0340 mgmtd: fix printing an empty data tree
We don't need to create an actual tree to print an empty tree, libyang
handles NULL just fine. The actual problem is that `yang_dnode_new`
creates a tree by validating it, and the validation creates all implicit
default nodes. Therefore, when called with "with-default" flags, instead
of getting an empty tree, we get a tree with all top-level default set.

ee1986f1b5 bgpd: Reinstall aggregated routes if using route-maps and it was changed
Without this change when we change the route-map, we never reinstall the route
if the route-map has changed.

We checked only some attributes like aspath, communities, large-communities,
extended-communities, but ignoring the rest of attributes.

With this change, let's check if the route-map has changed.

bgp_route_map_process_update() is triggered on route-map change, and we set
`changed` to true, which treats aggregated route as not the same as it was before.
