145368f547 Extends multipath support for OSPF.
Fixes cases where the same network or external route are propagated by
several OSPF routes and some other corner cases in next hop construction
and ECMP. Allows to specify whether external routes should be merged.

Thanks to Peter Christensen for the original patch.

859cbd75e1 Fixes a bug in (mainly) IPv6 BGP.
Stack variable may be used unitialized and that would lead to spurious
rta_free(), which may cause crash. The bug was introduced in 1.4.1 from
merging add-path branch.

Thanks to Peter Andreev for reporting it and Alexander V. Chernikov for
resolving it.

864f52a5f4 Fixes nasty bug in BFD.
When a BFD session is removed while being scheduled for notification,
the session stays in notify list and is removed twice, which leads to
a strange crash after a while.

d40c26594c Fixes issues with static protocol reconfiguration.
The old static route was not removed when the nexthop changed and the
new one was not viable (no neighbor).

48e5f32db6 Many changes in I/O and OSPF sockets and packet handling.
I/O:
 - BSD: specify src addr on IP sockets by IP_HDRINCL
 - BSD: specify src addr on UDP sockets by IP_SENDSRCADDR
 - Linux: specify src addr on IP/UDP sockets by IP_PKTINFO
 - IPv6: specify src addr on IP/UDP sockets by IPV6_PKTINFO
 - Alternative SKF_BIND flag for binding to IP address
 - Allows IP/UDP sockets without tx_hook, on these
   sockets a packet is discarded when TX queue is full
 - Use consistently SOL_ for socket layer values.

OSPF:
 - Packet src addr is always explicitly set
 - Support for secondary addresses in BSD
 - Dynamic RX/TX buffers
 - Fixes some minor buffer overruns
 - Interface option 'tx length'
 - Names for vlink pseudoifaces (vlinkX)
 - Vlinks use separate socket for TX
 - Vlinks do not use fixed associated iface
 - Fixes TTL for direct unicast packets
 - Fixes DONTROUTE for OSPF sockets
 - Use ifa->ifname instead of ifa->iface->name

f3e5917850 Enables multihop mode for IBGP by default.
This is more consistent with common usage and also with the behavior of
other implementations (Cisco, Juniper).

Also changes the default for gw mode to be based solely on
direct/multihop.
