	* stackstash.[ch]: Add a destroy notifier to StackStash

	* collector.c (collector_create_profile): Pass g_free as destroy
	notifier.

	* collector.c (collector_reset): Pass NULL as destroy notifier

	* profile.c (profile_load): Pass g_free here.

	* profile.c (struct Profile): Remove unused "Node" typedef

	* collector.c (resolve_symbols): Free the array here.

	* TODO: various updates.
