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.

Initial import for portaudio-devel-20060521 (at this moment also known
as portaudio version 19), a portable cross-platform Audio API.

PortAudio is a free, cross platform, open-source, audio I/O library.  It
lets you write simple audio programs in 'C' that will compile and run on
many platforms including Windows, Macintosh (8,9,X), Unix (OSS), SGI, and
BeOS. PortAudio is intended to promote the exchange of audio synthesis
software between developers on different platforms, and was recently
selected as the audio component of a larger PortMusic project that includes
MIDI and sound file support.

PortAudio provides a very simple API for recording and/or playing sound
using a simple callback function.  Example programs are included that
synthesize sine waves and pink noise, perform fuzz distortion on a guitar,
list available audio devices, etc.
