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.

With important help from kettenis@, guenther@, and jca@.
Repeated testing in ports bulk builds by naddy@.
Additional testing by jca@, sebastia@, dcoppa@, and others.
OK kettenis@ dcoppa@, and guenther@ on an earlier version.
Riding guenther@'s libc/librthread major bump.

Move the 10 (!) defintions of NULL to their own mini header file and
update the NULL definition for C++11. OK deraadt@ guenther@ kettenis@

gcc 2.x is dead

ok millert@

Protect fgetwln(), wcslcat() and wcslcpy() with __BSD_VISIBLE
OK tedu@ kettenis@

Add fgetwln(3) from FreeBSD and bump libc minor revision.

Per C99, wchar.h has to forward declare struct tm

Annotate wide character routines so they get protected by Wbounded.
OK millert@

Enable fmemopen(3) and open_{w,}memstream(3)

commiting on behalf of mpi@

Add support for mbsnrtowcs() and wcsnrtombs() to libc.

Bulk build test by naddy.

C99 says that both <wchar.h> and <stdint.h> should define WCHAR_MIN/MAX.

ok beck@, guenther@, millert@, miod@

Hook wcsftime(3) to the build; committing on behalf of espie

Add wscanf(3) and friends. Based on our scanf(3) implementation, with wide
character support changes based on code from FreeBSD.
ok espie guenther; man page help from schwarze

Add wcsdup(), from NetBSD.

ok deraadt matthew

As pointed out by Richard Guenther our definition
of NULL was incorrect for c++ compilers that aren't
gcc (or pretend to be gcc like clang).

ok miod@

Use __POSIX_VISIBLE not __POSIX_C_SOURCE to bracket the definitions
of wcscasecmp() and wcsncasecmp(). Noticed by naddy@ OK espie@

wcs(n)casecmp support, manpage comments from jmc@, okay deraadt@

Bring back wprintf. We've sorted out what to do for gcc2 and gcc3.
"Yes, go ahead then" deraadt

Back out wprintf until we've determined what to do for gcc2 and gcc3 arches.

Add fwprintf, swprintf, vfwprintf, vswprintf, vwprintf, and wprintf to libc.
Based on our vfprintf etc. implementations. Wide character parts based on

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.

Don't declare wcscoll() twice

Add wcstof(3) and wcstold(3).

ok miod@

First pass at removing clauses 3 and 4 from NetBSD licenses.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of

First pass at removing clauses 3 and 4 from NetBSD licenses.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

Adapt things to use __type_t instead of _BSD_TYPE_T_
Add new sys/_types.h header
Include machine/_types.h or sys/_types.h where applicable

This piece was missed in the _FOO_SOURCE -> __FOO_VISIBLE change set.
