ras2tiff, sgi2tiff, sgisv, and ycbcr are completely removed from the distribution. The libtiff tools rgb2ycbcr and thumbnail are only built in the build tree for testing. Old files are put in new 'archive' subdirectory of the source repository, but not in distribution archives. These changes are made in order to lessen the maintenance burden.
