Now it can handle a change in iface pattern structure.
It can add, remove and reconfigure interfaces, vlinks and areas.

Fixes many bugs in the old code and makes it much cleaner.

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).

And fixes one minor bug.

Finally, it is working.

are in single database. This avoids duplication of external LSAs and
fixes bug in external LSA distribution.

Origination of summary LSA works.
Routing table calculation works.
Virtual links works.

Well, I hope, OSPF is fully compatible with RFC2328!!!!

	- metric is 3 byte long now
	- summary lsa originating
	- more OSPF areas possible
	- virtual links
	- better E1/E2 routes handling
	- some bug fixes..

I have to do:
	- md5 auth (last mandatory item from rfc2328)
	- !!!!DEBUG!!!!! (mainly virtual link system has probably a lot of bugs)
	- 2328 appendig E

Thanks you Harry Moyes.
