Renato Westphal 8b93b03839 bgpd: fix sending of invalid nexthops on the wire 
The bpacket_reformat_for_peer() function rewrites the nexthop of outgoing
route updates on a per-peer basis in order to handle route-maps ("set
ip next-hop") and locally-originated routes missing a nexthop.

In the latter case, RFC 4271 says the following: "When announcing a
locally-originated route to an internal peer, the BGP speaker SHOULD use
the interface address of the router through which the announced network
is reachable for the speaker as the NEXT_HOP".

We were doing this for regular IPv4/IPv6 routes, but not for
VPN/EVPN/ENCAP routes, which were being announced with invalid nexthops
(0.0.0.0 or ::).

This patch fixes this problem.

FRRouting is free software that manages various IPv4 and IPv6 routing
protocols.

Currently FRRouting supports BGP4, BGP4+, OSPFv2, OSPFv3, RIPv1,
RIPv2, RIPng, PIM-SM/MSDP and LDP as well as very early support for IS-IS.

See the file REPORTING-BUGS to report bugs.
