Commit of build_consolidation branch

Squashed into one commit (see branch for details of the evolution of the branch). This brings gpcl6 and gxps into the Ghostscript build system, and a shared set of graphics library object files for all the interpreters. Also, brings the same configuration options to the pcl and xps products as we have for Ghostscript.

+xtiff 2.0
+
+xtiff is a tool for viewing a TIFF file in an X window.  It was written to
+handle as many different kinds of TIFF files as possible while remaining
+simple, portable and efficient.  xtiff requires X11 R4, the Athena Widgets
+and Sam Leffler's libtiff package (which can be found on ucbvax.berkeley.edu).

+ * Revision 1.0  90/05/07
+ *      Initial release.
+ * Revision 2.0  90/12/20
+ *      Converted to use the Athena Widgets and the Xt Intrinsics.
+ *
+ * Notes:
+ *
+ * According to the TIFF 5.0 Specification, it is possible to have
+ * both a TIFFTAG_COLORMAP and a TIFFTAG_COLORRESPONSECURVE.  This
+ * doesn't make sense since a TIFFTAG_COLORMAP is 16 bits wide and
+ * a TIFFTAG_COLORRESPONSECURVE is tfBitsPerSample bits wide for each
+ * channel.  This is probably a bug in the specification.
+ * In this case, TIFFTAG_COLORRESPONSECURVE is ignored.
+ * This might make sense if TIFFTAG_COLORMAP was 8 bits wide.
+ *
+ * TIFFTAG_COLORMAP is often incorrectly written as ranging from
+ * 0 to 255 rather than from 0 to 65535.  CheckAndCorrectColormap()
+ * takes care of this.
+ *
+ * Only ORIENTATION_TOPLEFT is supported correctly.  This is the
+ * default TIFF and X orientation.  Other orientations will be
+ * displayed incorrectly.
+ *
+ * There is no support for or use of 3/3/2 DirectColor visuals.
+ * TIFFTAG_MINSAMPLEVALUE and TIFFTAG_MAXSAMPLEVALUE are not supported.
+ *
+ * Only TIFFTAG_BITSPERSAMPLE values that are 1, 2, 4 or 8 are supported.
