Remove 2 non depend on, obsoletes libraries failing with new sigc++20

Remove libintl.so.9 compatibility link that was added in r374303 to
prevent massive PORTREVISION bumps.  Bump dependent ports that have not
been bumped since.

- Drop @dirrm* from and add empty directories to pkg-plists

Approved by:	portmgr blanket, kwm (for gnome@ ports)

Add USES=libtool to accessibility/atkmm and bump dependent ports

- Replace LIB_DEPENDS with USE_GNOME=gtkmm24
- Replace USE_GNOME=gnomehack with USES=pathfix
- Add USES=libtool

- Convert USE_GMAKE/BZIP2 to USES

Add NO_STAGE all over the place in preparation for the staging support (cat:
x11-toolkits)

Add an explicit dependency on pkgconf

* 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.

Presenting GNOME 2.18 for FreeBSD.  GNOME 2.18 is a departure from recent GNOME
releases in that it focuses more on stability and functionality than on
new features.  Not that it doesn't have its share of new and exciting
items.  See http://www.gnome.org/start/2.18/ for all the goodies in
this release.

GNOME 2.18 for FreeBSD would not have been possible without the hard work
of the FreeBSD GNOME Team and our intrepid band of testers including
J. W. Ballantine, Pawel Worach, Yasuda Keisuke, Pascal Hofstee, miwi,
Yoshihiro Ota, Vladimir Grebenschikov, Jukka A. Ukkonen,
Phillip Neumann, Franz Klammer, and Neal Delmonico.
