local formatting information.
	* language.h (language_defn):  Replace individual format info
	with language_format_info structs.
	* language.h (local_*_format, local_*_format_prefix,
	local_*_format_specifier, local_*_format_suffix):  New macros
	for binary/octal/decimal/hex formats to access info elements.
	* c-exp.y (c_language_defn):  Update for new format handling.
	* m2-exp.y (m2_language_defn):  Update for new format handling.
	* dbxread.c (language.h):  Include for partial-stab.h use.
	* defs.h (local_hex_format, local_hex_format_custom,
	local_hex_string, local_hex_string_custom):  Move to language.h.
	* language.c (local_hex_format_custom, local_hex_string,
	local_hex_string_custom, local_octal_format_custom):  Use new
	format handling.
	* language.c (unknown_language_defn, auto_language_defn,
	local_language_defn):  Update for new format handling.
	* printcmd.c (print_scalar_formatted):  Use new macros
	to access decimal and binary format info for printing.
	**** start-sanitize-chill ****
	* c-exp.y (chill_language_defn):  Update for new format handling.
	* ch-exp.y (CHARACTER_LITERAL):  Add support to yylex.
	* ch-exp.y (match_integer_literal):  Add function.
	* ch-exp.y (builtin_type_chill_char):  Add definition.
	* gdbtypes.h (builtin_type_chill_char):  Add declaration.
