[ospfd] Implement new ospf router subcommand "log-adjacency-changes [detail]"

Browse Source 
2006-06-28 Erik Muller <erikm@internap.com>

	* ospfd.h: Define 2 new struct ospf config flags:
	  OSPF_LOG_ADJACENCY_CHANGES and OSPF_LOG_ADJACENCY_DETAIL
	* ospf_nsm.c (nsm_change_state): Log adjacency changes if
	  requested.
	* ospf_vty.c (ospf_log_adjacency_changes): New command function
	  to implement ospf subcommand "log-adjacency-changes [detail]".
	  (no_ospf_log_adjacency_changes) Turn off log-adjacency-changes.
	  (show_ip_ospf) Show whether adjacency changes are logged.
	  (ospf_config_write) Add "log-adjacency-changes [detail]" to config.
	  (ospf_vty_init) Add ospf_log_adjacency_changes and
	  no_ospf_log_adjacency_changes.
	* ospfd.texi: Document new ospf router subcommand
	  "log-adjacency-changes [detail]".

Configures ospfd to log changes in adjacency. With the optional
detail argument, all changes in adjacency status are shown. Without detail,
only changes to full or regressions are shown.
