New commands for OSPF

Hello

I implemented two CLI commands for OSPF giving nice informative 
(and still machine parsable) representation of OSPF network graph
(based on datas from the LSA database).

The first command (show ospf topology) shows routers, networks
and stub networks, The second command (show ospf state) shows
also external routes and area-external networks and routers
propagated by given area boundary router.

The patch and examples of output are attached (if you wonder
why there are so many external routes, that is because i didn't
realized that if i import local routes to OSPF, i get them as
external routes even when they are already here as stub networks).

If you have some better ideas for command names and keywords
(especially 'state' command and 'xrouter' and 'xnetwork' keyword)
i would like to change that.
