52a43ae3b7 Minor changes in addresses.
Mainly changes IA_UNNUMBERED to IA_PEER and adds IA_HOST. Also do not
show broadcast addr in show interfaces. Nobody cares for that.

cfe34a316e Implements hostcache and recursive next hops.
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.

ff2857b03d Many changes in (mainly) kernel syncers.
- BSD kernel syncer is now self-conscious and can learn alien routes
- important bugfix in BSD kernel syncer (crash after protocol restart)
- many minor changes and bugfixes in kernel syncers and neighbor cache
- direct protocol does not generate host and link local routes
- min_scope check is removed, all routes have SCOPE_UNIVERSE by default
- also fixes some remaining compiler warnings

e366625c0e Fixes mixed-up messages on netlink socket
Under specific circumstances there might be two mixed-up
netlink sessions (one for scan, the other for route change
request). This patch separates netlink scans and requests
to two fds (and seq counters).

This should fix http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=428865

4c94a6c7e7 Do not repeat 'Invalid broadcast address' error message.
'Invalid broadcast address' error is reported only once for
an interface and not during every interface scan.

d7f3b30649 Ignore unknown netlink events.
Bird sometimes reported 'bird: nl_parse_link: Malformed message received'.
The cause is that bird asynchronously received netlink packet from
wireless driver about some wireless event on its link layer. In that
case bird shouldn't complain.

1567edea8d Bugfix for routing table breaking bug.
Here is a patch fixing a bug that causes breakage of a local routing
table during shutdown of Bird. The problem was caused by shutdown
of 'device' protocol before shutdown of 'kernel' protocol.  When
'device' protocol went down, the route (with local network prefix)
From different protocol (BGP or OSPF) became preferred and installed
to the kernel routing table. Such routes were broken (like
192.168.1.0/24 via 192.168.1.2). I think it is also the cause
of problem reported by Martin Kraus.

The patch disables updating of kernel routing table during shutdown of
Bird. I am not sure whether this is the best way to fix it, I would
prefer to forbid 'kernel' protocol to overwrite routes with
'proto kernel'.

The patch also fixes a problem that during shutdown sometimes routes
created by Bird remained in the kernel routing table.

The long resource/routing table dump printed upon startup is gone now
and if you wish to see it, just send bird SIGUSR1 or use the `debug'
commands.
