Sync tzselect, zdump, zic to TZDB 2024a.
This patch incorporates the following TZDB source code changes,
listed roughly in descending order of importance.
zic now supports links to links, needed for future tzdata
zic now defaults to '-b slim'
zic now updates output files atomically
zic has new options -R, -l -, -p -
zic -r now uses -00 for unspecified timestamps
zdump now uses [lo,hi) for both -c and -t
Fix several integer overflow bugs
zic now checks input bytes more carefully
Simplify and fix new TZDIR setup
Default time_t to 64 bits on glibc 2.34+ 32-bit
zic now generates TZ strings that conform to POSIX when all-year DST
zic -v now shows extreme-int tm_year transitions
Fix zic bug in last time type of Asia/Gaza etc.
Fix zic bug with Palestine after 2075
Fix bug uncovered by recent change to Iran history
Fix 'zic -b fat' bug with Port Moresby 32-bit data
Fix zic bug with -r @X where X is deduced from TZ
Fix bug with zic -r cutoff before 1st transition
Fix leap second expiry and truncation
Fix zic bug on Linux 2.6.16 and 2.6.17
Fix bug with 'zic -d /a/b/c' if /a is unwriteable
Don't mistruncate TZif files at leap seconds
Fix zdump undefined behavior if !USE_LTZ
zdump -v reports localtime+gmtime failures better
Fix zdump diagnostic for missing timezone
Don't assume nonempty argv
Port better to C23
Do not assume negative >> behavior
I18nize zdump a bit better
Port zdump to right_only installations
New tzselect menu option 'now'
tzselect can now use current time to help choose
Improve tzselect behavior for Turkey etc.
tzselect: do not create temporary files
tzselect: work around mawk bug with {2,}
tzselect: Port to POSIX awk, which prohibits -v newlines
Do not use empty RE in tzselect
Don't set TZ in tzselect
Avoid sed, expr in tzselect
tzselect: Fix problems with spaces in TZDIR
Improve tzselect diagnostics
Remove zic workaround for Qt bug 53071
Remove zic support for "min" in Rule lines
Remove zic support for zic -y, Rule TYPEs, pacificnew
Remove tzselect workaround for Bash 1.14.7 bug
* SHARED-FILES: Update to match current sync.
* config.h.in (HAVE_STRERROR): Remove; no longer needed.
* timezone/Makefile ($(objpfx)zic.o): Depend on tzdir.h.
($(objpfx)tzdir.h): New rule to build a placeholder.
* timezone/private.h, timezone/tzfile.h, timezone/version:
* timezone/zdump.c, timezone/zic.c: Copy verbatim from TZDB 2024a.
