8945f73d94 Ensures that msg_controllen includes last padding.
Although RFC 3542 allows both cases, Theo de Raadt thinks
he knows better, and msg_controllen without last padding
fails on OpenBSD.

Thanks to Job Snijders for the bugreport.

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

64534ea2f4 Fixes an issue when opposite address is mistaken for broadcast on ptp ifaces on BSDs.
Thanks to Lex van Roon for the bugreport and to Alexander V. Chernikov
for examining it and locating the problem.

f515e22924 Allows other than IA_PEER addresses on PtP ifaces on BSD.
Also fixes a potential problem with link-local dest_addrs
for IA_PEER addresses.

Thanks to Alexander V. Chernikov for the suggestion.

ef4a50be10 Better packet priority and traffic class handling.
Implements support for IPv6 traffic class, sets higher priority for OSPF
and RIP outgoing packets by default and allows to configure ToS/DS/TClass
IP header field and the local priority of outgoing packets.

094d2bdb79 Implements ADD-PATH extension for BGP.
Allows to send and receive multiple routes for one network by one BGP
session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.

Hostcache is a structure for monitoring changes in a routing table that
is used for routes with dynamic/recursive next hops. This is needed for
proper iBGP next hop handling.

c429d4a4ba Restrict export of device routes to the kernel protocol.
In usual configuration, such export is already restricted
with the aid of the direct protocol but there are some
races that can circumvent it. This makes it harder to
break kernel device routes. Also adds an option to
disable this restriction.
