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.
