Clean up print/ghostscript9-agpl-base and print/ghostscript9-agpl-x11 and
update them to version 9.23. Share CMap data with graphics/poppler-data
and update that to 0.4.9.

Details for print/ghostscript9-agpl-base:

• Update to 9.23.
• Drop external epag device.
• Always use fontconfig to find fonts.
• Use ports openjpeg instead of bundled.
• Use bundled lcms2, because upstream forked it.
• Drop dependency on gsfonts. Newer versions of the fonts are already included.
• Depend on poppler-data for CMap files. It has the same maps except Identity-H, Identity-UTF16-H, and Identity-V.
• Resolve conflict with gambc by moving bin/gsc to bin/gs instead of symlinking.
• Configure with --with-libiconv=maybe instead of --with-libiconv=native to prevent detecting libiconv from converters/libiconv if it happens to be installed. Also remove the ICONV option because it's part of the base system in all supported versions of FreeBSD.
• Enable thread safety.
• Remove all driver options and simply build with --with-drivers=ALL. They don't take up much space and don't require additional dependencies so options don't provide much value. This makes the port a lot easier to maintain.
• Set the internal font path to ${LOCALBASE}/share/fonts because the upstream default doesn't make much sense on FreeBSD.
• Make dependency on libijs optional because it only seems to be used by print/hpijs which is deprecated.
• Extract all directories and remove unwanted directories in post-patch so contents can be examined after 'make extract'.
• Strip gs and libgs.so. Reported by stage-qa.
• Install color profiles in share/color/icc, where other programs can find them.
• Remove old patches.

Details for print/ghostscript9-agpl-x11:

• Keep the Makefile similar to ghostscript9-agpl-base Makefile.
• Set PATCHDIR to ghostscript9-agpl-base/files so patches are shared.

Details for graphics/poppler-data:

• Update to 0.4.9.
• Replace post-patch with MAKE_ARGS.
• Add post-install to make all CMap files available in share/cmap so Ghostscript can use them too. Unfortunately, Poppler requires these files organised in subdirectories and Ghostscript wants them all in one directory, hence the hardlinks.
