time_rz: port to Solaris etc. Works around a tzname problem on platforms like Solaris that have tzname but not tm_zone, by setting tzname at the appropriate time and restoring it later. * lib/time_rz.c (tzname_address, tzname_value) [HAVE_TZNAME]: New static vars. (save_abbr) [HAVE_TZNAME]: Set them. (revert_tz) [HAVE_TZNAME]: Clear or use them. (restore_tzname): New function. (localtime_rz, mktime_z): Use it.
