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.

+dnl     release of your software. More frequent updates are unnecessary, and
+dnl     only guarantee that the current interface number gets larger faster.
+dnl  3. If the library source code has changed at all since the last update,
+dnl     then increment revision (`c:r:a' becomes `c:r+1:a').
+dnl  4. If any interfaces have been added, removed, or changed since the last
+dnl     update, increment current, and set revision to 0.
+dnl  5. If any interfaces have been added since the last public release, then
