In preparation of the update of glib remove the -reference ports

Those ports mainly concern old Gnome2 libraries, the behaviour of this infra
is not compatible with the meson build system (being used in newer version)
the documentation is provided otherwise in the other version

Drop build dependency on GNU m4.

m4 from base is able to do the job, if properly wrapped to mimic GNU m4

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Bump PORTREVISION for ports depending on the canonical version of GCC
defined via Mk/bsd.default-versions.mk which has moved from GCC 7.4 t
GCC 8.2 under most circumstances.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and

plus, as a double check, everything INDEX-11 showed depending on lang/gcc7.

Bump PORTREVISION for ports depending on the canonical version of GCC
in the ports tree (via Mk/bsd.default-versions.mk and lang/gcc) which
has now moved from GCC 6 to GCC 7 by default.

This includes ports
 - featuring USE_GCC=yes or USE_GCC=any,
 - featuring USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and those
 - with USES=compiler specifying one of openmp, nestedfct, c11, c++0x,
   c++11-lib, c++11-lang, c++14-lang, c++17-lang, or gcc-c++11-lib.

Adjust USES to fix building on gcc-based archs (in particular, powerpc64).

On the clang architectures, these changes have no effect: the baser
compiler already includes the needed features.

While here, remove now-redundant CXXFLAGS statements and pet portlint
(no other content change).

Tested on both powerpc64 and amd64.

* Add PORTSCOUT macros to only show stable gnome versions.
* Fix the PORTSCOUT macro in devel/glib20-reference/bsd.gnome-reference.mk
  so that all -reference ports get ignored.
* Add some PORTSCOUT=ignore:1 here and there for software that won't get
  any updates anymore. Or are slave ports, so only the master port will
  get checked.

Cleanup plist

Use MAKE_CMD

- Stage support for all -reference ports
- Nuke NOPORTDOCS, those ports are already IGNOREd with NOPORTDOCS

Approved by:	kwm (maintainer)

Add NO_STAGE all over the place in preparation for the staging support (cat:
devel part 2)

Don't try to remove directories we don't make.

Convert devel to USES=pkgconfig

* Update the glib to 2.34.3 and gtk20 to 2.24.17 and gtk30 to 3.6.4 which
  are the latest stable releases.
* Update vala to the newest stable release 0.18.1, also update a few ports
  in the gtk/gnome stack.
* The c++ bindings ports for glib, atk, gconf, etc, have now USE_GNOME toggles.
* Remove pkg-config run depends from glib20 and freetype2. This doesn't
  eliminate pkg-config run dependency completely, a second phase is needed
  and is planned.
* Support for .:run. and .:build. for USE_GNOME components was added.
  Currently only libxml2 and libxslt support this mechanism.
* Updates of the telepathy stack and empathy.
* Trim makefile headers, convert ports to new options, trim off library
  versions for some ports.
* Fix other ports so they build with the new glib version.

Update vala to the newest stable release 0.12.1.

Thanks to pav@ for doing multiple exp-runs, and marcus@ for repo-copies.
Full contributors acknowledgment will be given in the GNOME 3 import.

Install the tools in the NOPORTDOCS case.
We need them for other *mm-reference ports.

Presenting GNOME 2.28.1 for FreeBSD.  The official release notes for this
release can be found at http://library.gnome.org/misc/release-notes/2.28/ .
Officially, this is mostly a polishing release in preparation for GNOME 3.0
due in about a year.

On the FreeBSD front, though, a lot went into this release.  Major thanks
goes to kwm and avl who did a lot of the porting work for this release.
In particular, kwm brought in Evolution MAPI support for better Microsoft
Exchange integration.  Avl made sure that the new gobject introspection
repository ports were nicely compartmentalized so that large dependencies
aren't brought in wholesale.

But, every GNOME team member (ahze, avl, bland, kwm, mezz, and myself)
contributed to this release.

Fix the installation and plist when NOPORTDOCS is defined, bump the
PORTREVISION.

Reported by:    itetcu

Fix the plist, bump the PORTREVISION on glibmm-reference.

Add a full BUILD_DEPENDS on glibmm to fix build problems on pointyhat.

- Add header in these *-reference ports.
- Fix a few of pkg-descr by chase the rename.
- Move all PORTREVISION and PORTEPOCH to top with ?=.
- Put USE_X_PREFIX back in, but under REFERENCE_PORT, and remove PREFIX? and
  USE_XLIB. This fix ports to use the correct mtree when you change the prefix,
  for example:

        Incorrect: (Without USE_X_PREFIX)
        ================================
        # cd /usr/ports/x11-toolkits/gtk20
        # make -V MTREE_FILE
        /etc/mtree/BSD.x11-4.dist
        # make PREFIX=/tmp/foo -V MTREE_FILE
        /etc/mtree/BSD.local.dist <-- Here...
        ================================

- Add pkg-descr

Fix the packing list.

Move the glibmm programming reference to the glibmm-reference port.
