swi-prolog*: Update to 8.0.1

pkgsrc changes:
 - Rename swi-prolog to swipl to follow upstream nomenclature
 - Add all main packages (except X11) to swi-prolog-lite.
   After CMake migration in order to generate the documentation and being able
   to use it (e.g. via help/2) it is needed to add basic, archive, ssl and term
   packages.
   All X11 packages are provided by swi-prolog-packages.
 - Adjust pkgsrc Makefile-s logic to upstream CMake migration:
    o Uncoditionally disable not wanted packages in Makefile.common (to avoid
      possible PLIST mismatches; please note that this will probably disable
      tipc package on Linux!).
      All other installed packages are enabled/disabled via
      swi-prolog-{lite,packages,jpl} Makefile.
    o Add libarchive, ossp-uuid and openssl build dependency to
      swi-prolog-packages.  Despite these are provided by swi-prolog-lite
      they are needed as part of the build of swi-prolog-packages too.
    o Remove no more needed logic to check and eventually start X server to
      build documentation.  Should address PR pkg/42047.
 - Remove an unconditional CHECK_WRKREF_SKIP, this was needed on FreeBSD
   but unfortunately it is not clear why.  If this is still needed please let
   me know in order to try to investigate further and address that.
 - Bump API requirements to 8.0.1 in buildlink3.mk to be on the safe side
   now that shared libraries are provided on all platforms.

Changes:
8.0.1
-----
Indexing on multiple arguments together, indexing inside compounds,
Mode-directed tabling, saved states using ZIP files, many deployment
enhancements. Moved build environment to CMake and removed most of
the build tool dependencies. Builds documentation along with the
binary.

Please note that this is just a short summary. Unfortunately the
complete changelog is very long, full changelog can be found at:

Log message:
Use META_PACKAGE

Log message:
* If PLIST_SRC is explicitly set to an empty value in a package Makefile,
  then automatically generate a PLIST that says "${PKGNAME} has no files".

* If PLIST_SRC and GENERATE_PLIST are not set in a package Makefile,
  and no PLIST files exist, then fail during the package build with
  PKG_FAIL_REASON.

* Remove "intentionally empty" PLISTs again.

Now, the easy way to say that a package installs no files is to just
add the following to the package Makefile:

	PLIST_SRC=	# empty

Log message:
Re-add "intentionally empty" PLISTs for meta-packages and other packages
that directly manipulate empty PLISTs.

Modify plist/plist.mk so that if the PLIST files are missing and no
GENERATE_PLIST is defined, then the package fails to build.

Log message:
Remove empty PLISTs from pkgsrc since revision 1.33 of plist/plist.mk
can handle packages having no PLIST files.

Log message:
Allow for PKGREVISION's of its dependencies.

Log message:
Update swi-prolog* to 5.6.17.

The 5.6.x release consolidates the 5.5.x development stream started in 2004.
Highlights:
* UNICODE character set support
* Unbounded integer arithmetic and rational numbers
* New and faster CHR release
* Added clp(r) constraints over reals
* Many enhancements to the web and notably sematic web libraries
* Much more ...

Log message:
Point MAINTAINER to pkgsrc-users@NetBSD.org in the case where no
developer is officially maintaining the package.

The rationale for changing this from "tech-pkg" to \ 
"pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list).  Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
