- Split ghostscript into X11-independent and -dependent parts:

 * print/ghostscript{7,8,9,9-agpl}-base

   Installs Ghostscript binary, libgs, and related files.
   These ports do not depend on X11 libraries (i.e. x11* devices
   are not available).  USES=ghostscript will set dependency on
   one of them depending on GHOSTSCRIPT_DEFAULT.

   The default device is set to "display" or "bbox".

 * print/ghostscript{7,8,9,9-agpl}-x11

   Installs a shared library which provides X11 support to
   the installed Ghostscript binaries.  x11* devices will be
   enabled when the library is available.

   This depends on *-base (RUN_DEPENDS).  USES=ghostscript:x11
   will set dependency on one of them.

- Fix integer overflow reported as CVE-2015-3228.

- Update Uses/ghostscript.mk:

 * Add x11 keyword.  nox11 keyword is now obsolete.

 * Use packagename in *_DEPENDS line to prevent relationship between
   -base and -x11 packages from being broken.

- Fix x11/nox11 keyword and bump PORTREVISION in ports using
  USES=ghostscript to update dependency of pre-compiled packages.
