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.

824de84d48 Do not start with huge OSPF FIBs.
Most OSPF instances don't need 64k FIB fields. This change halves
resident memory usage on small OSPF networks.

e0a62ad0f8 Fixes a bug in duplicit configured stubnets.
If there was the same configured stubnet on local and remote
router, the remote route always won regardless of its cost.

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.

126683feed Filter language updates; new route attributes and datatype.
- Adds bgp_originator_id and bgp_cluster_list route attributes.
 - Adds dotted quad filter datatype (for router IDs, used by
   bgp_originator_id and ospf_router_id route attributes).
 - Fixes pair ~ pair set matching.
 - Documentation updates.

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.

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

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.

c27b2449d1 Shows source (Router ID) for OSPF routes and adds such attribute.
A sad thing is that we does not have a 'router_id' filter type,
so it must be given as decimal number in filters.
