Avoid collision by puting them in a different path which is anyway provided

audio/libcanberra: split a gtk2 from non graphic port

there was already a slave port for gtk3, now make a slaveport for gtk2 as
well.

While here fix the option definition which was wrongly done making libcanberra
have no options at all while libcanberra-gtk3 had and the opposite was expected

Use options helpers to simplify the port.
Drop the gtkdoc by default
bump revision and track no package for the 2 only port requiring the gtk2
library
Reduce the slave port to its bare minimal requirement

This change has been made in a slaveport instead of a flavor, because flavors
depending
on its own origin is not supported. this is a candidate for subpackages in the
futur.

note that this changes also removes gtk2 from the dependency path of many gtk3
only
 application

Remove # $FreeBSD$ from Makefiles.

Move some gnome@ ports to desktop@

As gnome@ is lacking active committers at the moment, transfer some of its
ports [1] up the stack to the desktop@ group, in hope that this way we get some
updates in as the set of people that "should feel responsible" grows.

As soon as gnome@ grows some committers again, this can (and should) of course
be reverted again.

[1] The list of ports chosen in this move consits of all the ports that are
required to build x11/kde5.

Remove no longer needed code that was reinplacing a symlink

PR:		216309

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

- Convert to USES=libtool and USES=pathfix
- Add INSTALL_TARGET=install-strip

Convert GMAKE to MAKE_CMD
Please note that lots of invocation of MAKE_CMD here are wrong as they do not
properly respect MAKE_ENV and friends

With hat:	portmgr

Simplify makefile and get rid of GMAKE call

Stagify.

Add NO_STAGE all over the place in preparation for the staging support (cat:
audio)

Update to 0.28.

Add gtk3 slave port.
