New POSIX xlocale implementation written from scratch.
Complete in the sense that all POSIX *locale(3) and *_l(3) functions
are included, but in OpenBSD, we of course only really care about
LC_CTYPE and we only support ASCII and UTF-8.

tzfile.h is an internal header that should never have been installed.
What's worse, the tzfile.h that gets installed is over 20 years old
and doesn't match the real tzfile.h in libc/time. This makes the
tree safe for /usr/include/tzfile.h removal. The TM_YEAR_BASE
define has been moved to time.h temporarily until its usage is
replaced by 1900 in the tree. Actual removal of tzfile.h is pending
a ports build. Based on a diff from deraadt@

Define NULL as a void * instead of a long integer, as required by Single Unix.
Kernel and bootblocks still use the old 0L value until all the NULL abuses
in the code are fixed.
