MAJOR CHANGES:

Fixed important bug in custom tags handling code..

CHANGES IN THE SOFTWARE CONFIGURATION:

Applied patch from Patrick Welche (all scripts moved in the 'config' and 'm4' directories).
SConstruct, libtiff/SConstruct: Added the first very preliminary support for SCons software building tool (http://www.scons.org/). This is experimental infrastructure and it will exist along with the autotools stuff.
port/lfind.c: Added lfind() replacement module.

CHANGES IN LIBTIFF:

tif_dir.c: When prefreeing tv->value in TIFFSetFieldV also set it to NULL to avoid double free when re-setting custom string fields as per: http://bugzilla.remotesensing.org/show_bug.cgi?id=922
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.

CHANGES IN THE TOOLS:

tiffcp.c: Fixed WhitePoint tag copying.

CHANGES IN THE CONTRIB AREA:

tiffdump.c: Added support for TIFF_IFD datatype.
addtiffo/{tif_overview.c, tif_ovrcache.c, tif_ovrcache.h}: Make overviews working for contiguous images.
