Martin Mares 7d83290780 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.
