Log message:
Remove libscsi and the two packages using it, tosha and cdd.

The FreeBSD SCSI library on which libscsi was based, was removed in 1998.
The two other packages were last updated 1997 and 2001, respectively.
Better software exists (e.g. cdparanoia, cdrecord).

Ok agc@, gdt@

Log message:
devel/libscsi: Disable FreeBSD and DragonFly

The FreeBSD SCSI library, on which this package is based, was removed in
1998 and replaced with CAM-SCSI.  DragonFly never had it.  Neither
platform has the required <sys/scsiio.h>.  Other patches are
NetBSD-specific, so the scope of this package must be narrowed once again.

Log message:
This package is BSD-specific; set ONLY_FOR_PLATFORM.

Log message:
user-destdir support

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Drop -Werror, it doesn't appear to be warns safe:
scsi.c:1047: warning: pointer type mismatch in conditional expression

Log message:
Fixed gcc error message:

scsi.c:1047: warning: dereferencing 'void *' pointer
scsi.c:1047: error: void value not ignored as it ought to be

The reason is that scsireq_t->data has now (NetBSD 4.99.30) the type
void *, which seems to have been char * before.

Log message:
Mechanically replaced man/* with ${PKGMANDIR}/* in the definition of
INSTALLATION_DIRS, as well as all occurrences of ${PREFIX}/man with
${PREFIX}/${PKGMANDIR}.

Fixes PR 35265, although I did not use the patch provided therein.

Log message:
Change the format of BUILDLINK_ORDER to contain depth information as well,
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.

For example, "make show-buildlink3" in fonts/Xft2 displays:

	zlib
	fontconfig
	    iconv
	    zlib
	    freetype2
	    expat
	freetype2
	Xrender
	    renderproto

Log message:
Track information in a new variable BUILDLINK_ORDER that informs us
of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.
