  time_rz: port better to MinGW
  
  Don't change tzname, as this makes MinGW dump core (Bug#21020).
  Instead, store the tzname copy in the struct tm_zone object.
  Problem reported by Eli Zaretskii in: http://bugs.gnu.org/21020#48
  * lib/strftime.c [!_LIBC]:
  * lib/time_rz.c: Include time-internal.h.
  * lib/strftime.c (strftime_case_) [!HAVE_TM_ZONE]: Infer the zone
  name from *TZ rather than from TZNAME, doable because *TZ now has
  a tzname_copy member.
  * lib/time-internal.h: New file, with contents taken from
  lib/time_rz.c.  It's separate because strftime.c now accesses
  struct tm_zone members.
  (struct tm_zone) [HAVE_TZNAME && !HAVE_TM_ZONE]:
  New member tzname_copy.
  * lib/time_rz.c (struct tm_zone): Move to time-internal.h.
  (tzalloc) [HAVE_TZNAME && !HAVE_TM_ZONE]:
  Initialize tzname_copy member.
  (save_abbr) [HAVE_TZNAME && !HAVE_TM_ZONE]: Save abbreviation
  in tzname_copy member.
  (revert_tz) [HAVE_TZNAME]: Remove no-longer-needed tzname saving.
  (restore_tzname): Remove; no longer needed.  All calls removed.
  * modules/time_rz (Files): Add lib/time-internal.h.
