* NEWS: Mention "info auto-load-scripts".

* python/py-auto-load.c (struct auto_load_pspace_info): New member
	script_not_found_warning_printed.
	(init_loaded_scripts_info): Renamed from create_loaded_scripts_hash,
	all callers updated.  Initialize script_not_found_warning_printed.
	(get_auto_load_pspace_data_for_loading): New function.
	(maybe_add_script): New function.
	(source_section_scripts): Simplify.  Only print one warning regardless
	of the number of auto-load scripts not found.
	(clear_section_scripts): Clear script_not_found_warning_printed.
	(auto_load_objfile_script): Record script in hash table.
	(count_matching_scripts): New function.
	(maybe_print_script): Renamed from maybe_print_section_script, all
	callers updated.  Rewrite to use ui_out_*.
	(info_auto_load_scripts): Renamed from
	maintenance_print_section_scripts, all callers updated.
	(gdbpy_initialize_auto_load): "maintenance print section-scripts"
	renamed as "info auto-load-scripts".
