[ospfd] trivial: NSM AdjChange should print event, declutter core functions

2006-07-10 Paul Jakma <paul.jakma@sun.com>

	* ospf_nsm.c: (nsm_notice_state_changes) Move state change
	  logging code to new func to declutter nsm_change_state and
	  ospf_nsm_event.
	  Log event with AdjChange, it's useful to know.
	  (nsm_change_state) move adjchange and snmp logging to previous.
	  (ospf_nsm_event) call nsm_notice_state_changes from here.
	  Move the debug message to entry of function, so it gets out
	  even if something goes wrong.
