was done for NB config output but I missed it for regular vty output.

The current maximum-prefix-out topo-test starts a configuration with a
maximum-prefix-out.
Test the application of new maximum-prefix-out value without clearing
the neighbor.

Abstract:
- The command "neighbor PEER maximum-prefix-out NUMBER" cannot be applied
without clearing the BGP neighbor.
- Apply the maximum-prefix-out value as soon as it is modified without
clearing the neighbor.
subgroup_update_packet() and subgroup_withdraw_packet() respectively
manages the announcement and withdrawal BGP message to the peer.
subgrp->scount counter counts the number of sent prefixes.
Before the patch, the maximum out prefix limitation was applied in
subgroup_update_packet() in order that subgrp->scount never exceeds the
limit. Setting a limit inferior to the effective number of sent prefix
did not result in sending any withdrawal message to reduce the number of
sent prefixes. Without clearing the BGP neighbor, the limitation only
applied to the announcement of new prefixes when the limitation was
over.
With the patch, the limitation is checked in subgroup_announce_check().
The function is intended to say whether a prefix has to be announced in
regards to the prefix-list, route-map... Now when a maximum-prefix-out
value is changed/removed, the neighbor AFI/SAFI table is re-parsed in
the same way as for the application of route-map, prefix-lists...

Fixes#9720. When updating an ECMP inter-area route, we compute
a new route and check whether that already exists. If so, we keep the old
route and only update its nexthops. Previously, we merged the new route's
nexthops into the old one's, but this way, it's impossible to remove
nexthops from the old route, resulting in stale nexthops.
This commit fixes this by first removing all nexthops from the old route and
then copying all nexthops from the new route into it. If the new route has
fewer nexthops, the old one will have as well afterwards.

BGP EVPN custom `union gw_addr` is basically the same thing as a common
`struct ipaddr` but it lacks the address family which is needed in some
cases.

This code is populating a temporary variable `add` instead of the attr.
Initially this variable was later copied to the attr but the copying was
erroneously deleted by 0a50c2481. Directly populate the attr to restore
the correct behavior.

Here we try to compare the new attr with the existing one but this call
compares the existing index with zero instead. attrhash_cmp already
compares indexes using overlay_index_same so this call is both wrong and
useless.
