* 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.
