* include/time.h: Declare __tzset_parse_tz and __tzset_compute.

	* time/tzset.c (tzset_internal): Break TZ string parsing out into
	__tzset_parse_tz and updating of daylight, timezone, tzname into
	update_vars.
	(__tz_compute): Renamed from tz_compute.  Take additional parameters.
	(__tz_convert): Updating of tm_isdst, tm_zone, and tm_gmtoff now
	happens in __tz_compute.
	* time/tzfile.c (__tzfile_read): Also read TZ string.
	(find_transition): Fold into __tzfile_compute.
	(__tzfile_compute): For times beyond the last transition try to
	use the TZ string.
	* timezone/tst-timezone.c: Information in daylight and tzname does
	change for Asia/Tokyo timezone with more concrete information.
	Remove the test.

	* include/stdio.h: Add libc_hidden_proto for ftello.
	* libio/ftello.c: Add libc_hidden_def.
