build: Remove embedded gl2ps. Require gl2ps as external dependency. * NEWS: Announce that gl2ps is no longer distributed with Octave. * build-aux/common.mk: New AC_SUBST macro GL2PS_LIBS. * configure.ac: When building native graphics, test for gl2ps.h header. If not found, print a warning and disable printing of FLTK figures. * libinterp/corefcn/gl2ps-renderer.cc, libinterp/corefcn/gl2ps-renderer.h: Only compile files if HAVE_GL2PS_H is true. * libinterp/dldfcn/__init_fltk__.cc(draw): Use #ifdef HAVE_GL2PS_H to either print figure, or issue a warning when gl2ps is not available. * libinterp/link-deps.mk: Add GL2PS_LIBS to libinter link dependencies * libinterp/corefcn/module.mk: Remove gl2ps.h, gl2ps.c from build system. * libinterp/corefcn/gl2ps.c, libinterp/corefcn/gl2ps.h: Removed from distribution.
