Historically, to work around CVS limitations, imports on the tzcode
vendor branch were split into subdirectories, which were then merged to
their respective counterparts in contrib. In the Git era, this split is
unnecessary and adds more work.
Undo the split for the most recent vendor import of tzcode 2010n to
prepare for the vendor import of tzcode 2022c.
* Makefile Change LOCALTIME default from "Factory" to "GMT";
do not compile "factory" file
(but keep it in the distribution).
* Theory Remove reference to "Factory" zone.
* localtime.c Initialize ttinfo structures filled by tzparse
(thanks to Ravindra for reporting a valgrind warning).
* zic.c Fix generation of POSIX strings for zones with
rules using "weekday<=n" forms of dates
(thanks to Lei Liu for finding the problem).
Also, limit output for non-POSIX-specificable zones
defined to follow the same rules every year.
(Note that no zones of either of the above types
appear in the distribution; these changes cater to
add-on zones).

* asctime.c - Set errno to EINVAL and return
"??? ??? ?? ??:??:?? ????\n"
if asctime_r is called with a NULL struct tm pointer.
(Note that asctime_r is called by ctime_r and asctime;
asctime is called by ctime.)
* localtime.c - Set errno to EINVAL and return WRONG
if time1 is called with a NULL struct tm pointer;
avoid dereference if a NULL struct tm pointer is
passed to timelocal, timegm, or timeoff.
(Note that time1 is called by mktime,
timegm, and timeoff; mktime is called by timelocal.)

primarily bugfixes, but is also contains a disclaimer of copyright.
As we are completely off the vendor branch here, this import has
no effect on the source tree.
