Log message:
	* libc/time/strftime.c: Add support for era and alt_digits data from
	LC_TIME locale category.  Conditionalize using _WANT_C99_TIME_FORMATS
	flag.
	(STRTOUL): Define differently for building strftime or wcsftime.
	(STRCPY): Ditto.
	(STRCHR): Ditto.
	(STRLEN): Ditto.
	(CHECK_LENGTH): Define to simplify code.
	(era_info_t): New type to store era info.
	(get_era_info): New function to fetch era info matching incoming
	struct tm.
	(free_era_info): New function to free era info.
	(alt_digits_t): New type to store alternative digits.
	(get_alt_digits): New function to convert alt_digits string into
	alt_digits_t structure.
	(free_alt_digits): New function to free alt_digits info.
	(conv_to_alt_digits): New function to convert unsigned value into
	alternative digits.
	(strftime): Conditionalize on _WANT_C99_TIME_FORMATS.  If
	_WANT_C99_TIME_FORMATS is defined, define as just a wrapper function
	providing era_info and alt_digits pointers and call ...
	(__strftime): Rename from strftime and make static if
	_WANT_C99_TIME_FORMATS is defined.  Add parameters for era_info and
	alt_digits pointers.  Handle conversion modifiers according to
	POSIX-1.2008.  Redefine %F and %Y according to POSIX.  Add default case
	to allow to bail out on invalid conversion specifiers.
