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.

0ea8fb4abe Fixes and enhancements in 'show ospf state' command.
Now it shows a distance, option to change showing reachable/all network
nodes and better handling of AS-external LSAs in multiple areas. The
command 'show ospf topology' was changed to not show stubnets in both
OSPFv2 and OSPFv3 (previously it displayed stubnets in OSPFv2).

7969ea3b41 Fixes a bug in OSPF on NBMA interfaces.
A very tricky bug. OSPF on NBMA interfaces probably never really worked.
When a packet was sent to multiple destinations, the checksum was
calculated multiple times from a packet with already filled checksum
field (from previous calculation). Therefore, many packets were sent
with an invalid checksum.

 - Fixes pair ~ pair set matching.

53434e44a9 Better flushing of interfaces.
When device protocol goes down, interfaces should be flushed
asynchronously (in the same way like routes from protocols are flushed),
when protocol goes to DOWN/HUNGRY.

This fixes the problem with static routes staying in kernel routing
table after BIRD shutdown.

- 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

dca75fd7c2 Removes phantom protocol from the pipe design.
It seems that by adding one pipe-specific exception to route
announcement code and by adding one argument to rt_notify() callback i
could completely eliminate the need for the phantom protocol instance
and therefore make the code more straightforward. It will also fix some
minor bugs (like ignoring debug flag changes from the command line).

c83876265e Fixes a tricky bug in the pipe protocol.
When uncofiguring the pipe and the peer table, the peer table was
unlocked when pipe protocol state changed to down/flushing and not to
down/hungry. This leads to the removal of the peer table before
the routes from the pipe were flushed.

The fix leads to adding some pipe-specific hacks to the nest,
but this seems inevitable.

6cb8f742f1 Better handling of well-known communities.
Process well-known communities before the export filter (old behavior is
to process these attributes after, which does not allow to send route
with such community) and just for routes received from other BGP
protocols. Also fixes a bug in next_hop check.

ea89da381f Workaround for stupid callback scheduler.
There is no reak callback scheduler and previous behavior causes
bad things during hard congestion (like BGP hold timeouts).

Smart callback scheduler is still missing, but main loop was
changed such that it first processes all tx callbacks (which
are fast enough) (but max 4* per socket) + rx callbacks for CLI,
and in the second phase it processes one rx callback per
socket up to four sockets (as rx callback can be slow when
there are too many protocols, because route redistribution
is done synchronously inside rx callback). If there is event
callback ready, second phase is skipped in 90% of iterations
(to speed up CLI during congestion).

f9bdcad469 Fixes type mismatch in OSPF printf statements.
Mixing ip_addr and u32 does bad things on Ultrasparc.
Although both have the same size. Fascinating.
It was not catched by compiler because of varargs.

29c430f856 Changes handling of AS_PATH_CONFED_* segments in AS_PATH.
Although standard says that if we receive AS_PATH_CONFED_*
(and we are not a part of a confederation) segment, we should
drop session, nobody does that and it is unwise to do that.

Now we drop session just in case that peer ASN is in
AS_PATH_CONFED_* segment (to detect peer that considers BIRD
as a part of its confederation).
