2006-09-11  Balazs Scheidler <bazsi at balabit.hu>

	(log_writer_free): removed stats_unregister_counter, fixed a memory
	leak by freeing all elements in the logwriter queue,
	(log_writer_options_init): fixed a possible memory leak by freeing
	the option structure contents before overwriting it with new values,

	* src/main.c (main_loop_run): added stats_cleanup_orphans() call

	* src/stats.c (stats_counter_free): new function,
	(stats_register_counter): added special case for orphaned counters,
	save "shared" value in the StatsCounter structure,
	(stats_orphan_counter): new function, orphanes a counter that can
	thus be reused by a new configuration upon the receiption of a HUP signal,
	(stats_unregister_counter): use stats_counter_free instead of
	open-coding it,
	(stats_cleanup_orphans): free all orphaned counters, to be called
	after a reload
