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.
