	* tracepoint.c (tracepoint_list, stepping_list): Remove.
	(clear_collection_list): Free fields 'aexpre_list' and 'list'
	in collection_list.
	(do_clear_collection_list, init_collection_list): New.
	(encode_actions): Add local variables 'tracepoint_list' and
	'stepping_list'.  Call init_collection_list and make cleanup
	which calls do_clear_collection_list.  Don't call
	clear_collection_list.
	(_initialize_tracepoint): Delete references to
	'tracepoint_list' and 'stepping_list'.
