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:
Compiles and works fine in DragonFly and should work fine in OpenBSD (at
least upstream tarball does).

Log message:
Update to version-3.0.2.  Many, many changes--please see
the ChangeLog for details, they are way too numerous to
list here.

Bump BUILDLINK_API_DEPENDS.
TODO: use misc/pciids?

Log message:
Add DESTDIR support. Split install -d command as it is not portable.

Log message:
# subdir build in libs, followed by linking with it, without .WAIT
MAKE_JOBS_SAFE=        NO

Log message:
pkglint cleanup; update HOMEPAGE/MASTER_SITES.

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.

Log message:
Aligned the last line of the buildlink3.mk files with the first line, so
that they look nicer.
