originating RP, it will drop the message.
* SA messages are forwarded away from the RP address only.
* SA messages are not forwarded within the mesh group.

Add a new topology test for `aggregate-address` to test
`matching-MED-only` and its combination with `summary-only`.
Signed-off-by: Rafael Zalamena <rzalamena@opensourcerouting.org>
Add code to handle MED matching:
- When MED matches act as normal.
- When MED doesn't match do the following:
* Uninstall the aggregate route
* Unsuppress routes (if using summary-only)
- When MED didn't match, but now matches:
* Install the aggregate route
* Suppress all routes (if using summary-only)

NetBSD and DragonFlyBSD support reporting of route(4) overflows
by setting the socket option SO_RERROR.
This is handled the same as on Linux by exiting with a -1 error code.

For `no router bgp` without ASN check candidate
config for default bgp instance presence to avoid
failure from checking backend db where bgp instance
may not be created.
This situation can be seen in transactional cli mode
with following config.
bharat(config)# router bgp 101
bharat(config-router)# exit
bharat(config)# no router bgp
% No BGP process is configured
bharat(config)# no router bgp
% No BGP process is configured

move `router bgp` nb callback at `bgp` node level
to have access to bgp context at neighbor and peer-group
level and align create/destroy callbacks call during
no router bgp.
Earlier `no router bgp` is performed first global destroy
callback is called which essentially removes `bgp context`
then it calls to remove (parallel nodes) neighbor and peer-group
which does not have access to bgp context.
Moving router bgp at bgp solves this destroy callback ordering issue.

Remove the nexthop_same_firsthop() api and just call nexthop_same().
