 SConstruct, libtiff/SConstruct: Added the first very preliminary

<font size="+3">C</font>HANGES IN LIBTIFF:

 tif_dir.c: Fixed up support for swapping "double complex"

	values (128 bits as 2 64 bits doubles).  GDAL gcore tests now

	pass on bigendian (macosx) system.

	
 libtiff/{tif_dirread.c, tif_dirinfo.c}: Do not upcast BYTEs to

	SHORTs in the TIFFFetchByteArray(). Remove TIFFFetchExtraSamples()

	function, use TIFFFetchNormalTag() instead as per bug

		http://bugzilla.remotesensing.org/show_bug.cgi?id=831

	Remove TIFFFetchExtraSamples() function, use TIFFFetchNormalTag()

	instead.

	
 tif_print.c: Fixed printing of the BYTE and SBYTE arrays.

	
 tif_write.c: Do not check the PlanarConfiguration field in

	the TIFFWriteCheck() function in case of single band images (as per

	TIFF spec).

	
 libtiff/{tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_print.c}:

	Make FieldOfViewCotangent, MatrixWorldToScreen, MatrixWorldToCamera,

	ImageFullWidth, ImageFullLength and PrimaryChromaticities tags custom.

<font size="+3">C</font>HANGES IN THE TOOLS:

	
 tiffcp.c: Fixed WhitePoint tag copying.

<font size="+3">C</font>HANGES IN THE CONTRIB AREA:
