Ben Gras 2fe8fb192f Full switch to clang/ELF. Drop ack. Simplify.
There is important information about booting non-ack images in
docs/UPDATING. ack/aout-format images can't be built any more, and
booting clang/ELF-format ones is a little different. Updating to the
new boot monitor is recommended.

Changes in this commit:

	. drop boot monitor -> allowing dropping ack support
	. facility to copy ELF boot files to /boot so that old boot monitor
	  can still boot fairly easily, see UPDATING
	. no more ack-format libraries -> single-case libraries
	. some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases
	. drop several ack toolchain commands, but not all support
	  commands (e.g. aal is gone but acksize is not yet).
	. a few libc files moved to netbsd libc dir
	. new /bin/date as minix date used code in libc/
	. test compile fix
	. harmonize includes
	. /usr/lib is no longer special: without ack, /usr/lib plays no
	  kind of special bootstrapping role any more and bootstrapping
	  is done exclusively through packages, so releases depend even
	  less on the state of the machine making them now.
	. rename nbsd_lib* to lib*
	. reduce mtree

.Sh NAME
.Nm wcscoll
.Nd compare wide strings according to current collation
.Sh LIBRARY
.Lb libc
.Sh SYNOPSIS
.In wchar.h
.Ft int
.Fn wcscoll "const wchar_t *s1" "const wchar_t *s2"
.Sh DESCRIPTION
The
.Fn wcscoll
function compares the nul-terminated strings
.Fa s1
and
.Fa s2
according to the current locale collation order.
In the
.Dq Li C
locale,
.Fn wcscoll
is equivalent to
.Fn wcscmp .
.Sh RETURN VALUES
The
.Fn wcscoll
function returns an integer greater than, equal to, or less than
0, if
.Fa s1
is greater than, equal to, or less than
.Fa s2 .
.Pp
No return value is reserved to indicate errors;
callers should set
.Va errno
to 0 before calling
.Fn wcscoll .
If it is non-zero upon return from
.Fn wcscoll ,
an error has occurred.
.Sh ERRORS
The
.Fn wcscoll
function will fail if:
.Bl -tag -width Er
.It Bq Er EILSEQ
An invalid wide-character code was specified.
.It Bq Er ENOMEM
Cannot allocate enough memory for temporary buffers.
.El
.Sh SEE ALSO
.Xr setlocale 3 ,
.Xr strcoll 3 ,
.Xr wcscmp 3 ,
.Xr wcsxfrm 3
.Sh STANDARDS
The
.Fn wcscoll
function conforms to
.St -isoC-99 .
.Sh BUGS
The current implementation of
.Fn wcscoll
function disregards
.Dv LC_COLLATE
locales, and falls back to using the
.Fn wcscmp
function.
