print/ghostscript7*: Deprecate and set expiration date to 2023-06-30

7.X-series are more than 20 years old by now and have been unsupported
for almost as long so it's about time to let go of these ports.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

print: remove 'Created by' lines

Fix CONFLICTS entries of multiple ports

There have been lots of missing CONFLICTS_INSTALL entries, either
because conflicting ports were added without updating existing ports,
due to name changes of generated packages, due to mis-understanding
the format and semantics of the conflicts entries, or just due to
typoes in package names.

This patch is the result of a comparison of all files contained in
the official packages with each other. This comparison was based on
packages built with default options and may therefore have missed
further conflicts with optionally installed files.

Where possible, version numbers in conflicts entries have been
generalized, some times taking advantage of the fact that a port

*/*: Remove redundant '-[0-9]*' from CONFLICTS_INSTALL

The conflict checks compare the patterns first against the package
names without version (as reported by "pkg query "%n"), then - if
there was no match - agsinst the full package names including the
version (as reported by "pkg query "%n-%v").

- 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
