Remove folks04, it no longer used after the GNOME 3 import.

Cleanup plist

The FreeBSD GNOME team proudly presents GNOME 3.14 and Cinnamon 2.2.
Gnome 3.14.1 and Cinnamon 2.2.16 are supported on FreeBSD 9.3-RELEASE and up.

This commit removes the old GNOME 2 desktop, bindings and some ports that
can't be compiled. A few ports where updated to more recent versions to
allow them to compile with this update.

Apart from updating ports to newer versions

GDM is more integrated with gnome-shell now, and handles several things for
the GNOME desktop such as screen locking. If you want to use GNOME 3 via
startx, you will have to add your own lock screen/screensaver. For example
xscreensaver
can be used for sessions started without GDM.

Shell Extensions can be installed via https://extensions.gnome.org/ , we have

- Set CPPFLAGS and LIBS in a number of ports so configure can find libintl.h
  and libintl.so.  This fixes a problem where DATADIRNAME gets an incorrect
  value which causes locale files to be installed in the wrong place.
- The only configure checks that still need to be patched are related
  to intltool so move DATADIRNAME patching from USES=pathfix to
  USE_GNOME=intlhack.

- games/klavaro: remove excessive dependencies
- japanese/libskk: add INSTALL_TARGET=install-strip
- math/libqalculate: add INSTALL_TARGET=install-strip and remove pthread
  patching
- multimedia/freetuxtv: remove excessive dependencies
- science/gramps: fix shared-mime-info use

- Switch to USE_GNOME=introspection

PR:		185916

When linking a library libA with a library libB using libtool, if libB.la
exists, libtool will add all libraries libB.la refers to (dependency_libs
field) to the linker command line and store them in the dependency_libs
field of libA.la.  So everything that subsequently links with libA will also
link to these extra libraries.  This causes too much overlinking.

This commit modifies Mk/Uses/libtool.mk so it empties the dependency_libs
field in .la libraries during staging.  However, because .la libraries have
very limited use when dependency_libs is empty it makes sense to completely
remove them during staging.

So with this commit USES=libtool is modified to remove .la libraries and a
new form (USES=libtool:keepla) is introduced in case they need to be kept
(dependency_libs is still emptied).

Support stage

Fix conflicts in pkgname with net-im/folks

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

Add an explicit dependency on pkgconf

- Convert USE_GETTEXT to USES (part 1)

Approved by:	portmgr (bapt)

Add LATEST_LINK [1]
While here, switch to USES=pathfix, spell PORTREVISION correct and s/=/+=/
for CPPFLAGS and LDFLAGS

* 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.
