Added pointer to network to RTE. The complications with passing NET separately

rte_discard and rte_dump don't need net * as parameter.

Generate router_id automatically if possible (standard "smallest of local
...
regular interface addresses" rule).
Protocols should NOT rely on router_id existence -- when router ID is not
available, the router_id variable is set to zero and protocols requiring
valid router ID should just refuse to start, reporting such error to the log.

Since almost every UNIX system requires different techniques for reading

the kernel routing table as opposed to modifying it which is approximately
the same on non-netlink systems, I've split the kernel routing table
routines to read and write parts. To be implemented later ;-)

After contemplating about RIP route timeouts for a long time, I've implemented
...
protocol callbacks for route insertion and deletion from the central table.
RIP should maintain its own per-protocol queue of existing routes, scan it
periodically and call rte_discard() for routes that have timed out.

Each protocol now hears even its own routes and needs to make its own
...
loop detection. This is needed since both RIP and OSPF handle multiple
neighbors and they need to redistribute routes learned from each neighbor
to the remaining ones.

Solve chicken-and-egg problems with protocol startup. We now queue all inactive

protocols and don't send route/interface updates to them and when they come up,
we resend the whole route/interface tables privately.
Removed the "scan interface list after protocol start" work-around.
