* isis_adjacency.c: Stop expire timer while deleting adjacency.
	* isis_events.c: Stop pseudo LSP thread while resigning circuit from
	  level.
	* isis_route.c: Fix compiling with EXTREME_DEBUG. Mark route as not
	  in sync with zebra if it's changed.
	* isis_spf.c: Schedule route validating etc even if tent was empty.
	  It's probably because we just don't have any adjacencies.
	* isisd.c: Write minimum spf interval into configuration.
