	* c-format.c (enum format_specifier_kind, kind_descriptions): New.
	(struct format_wanted_type): Replace field "name" with "kind", add
	"format_start" and "format_length".
	(check_format_info_main): Fill in new fields.  Fill in
	FORMAT_WANTED_TYPES even for missing arguments.  Move checks
	after the final NUL outside the while loop.  Do not include
	width and precision modifiers in the format_start/format_length
	of the main format.
	(check_format_types): Remove FORMAT_START and FORMAT_LENGTH
	arguments.  Compute WANTED_TYPE first so that format_type_warning
	can be called for missing arguments.  Adjust calls to
	format_type_warning.
	(format_type_warning): Fetch as much information as possible
	from format_wanted_type.  Adjust printing now that every
	warning has a "descr", as well as for missing argument warnings
	and to include % sign for format specifiers.
