Fix putenv race conditions with undefined behavior.
Do all putenv calls before Emacs creates any threads.
Use a safer way to modify the TZ environment variable in the
presence of multiple threads. For further thread-safety,
prefer localtime_r and gmtime_r to localtime and gmtime,
and prefer struct tm's tm_gmtoff (if available) to calling
both localtime_r and gmtime_r.
* configure.ac (LOCALTIME_CACHE): Remove.
We needn't worry about SunOS 4 any more; Sun dropped support in 2003.
All uses of LOCALTIME_CACHE removed. This simplifies the fix.
(tzalloc): Add check for this function.
* admin/merge-gnulib (GNULIB_MODULES): Add time_r, since Emacs now
calls localtime_r and gmtime_r directly.

before Emacs goes multithreaded.

thread-safe enough for Emacs.

(Fencode_time): Use mktime_z, for better thread-safety.
(set_time_zone_rule): Now static. Rewrite to be mostly thread-safe,

Do not reclaim storage that is in the environment; let it leak.
Always call tzset, since localtime_r does not.
