gnome.mk: rename gdkpixbuf2 to gdkpixbuf to prepare for port move

The GTK 1-based gdk-pixbuf has not existed for some time.

No functional or package changes.

*/*: Bump consumers of x11-toolkits/gtk30

New version of gtk3 in tree

XFCE: Cleanup dependencies

- Update xfce.mk to avid forcing too many dependencies on consumers
- Change dependency on garcon to reference libgarcon-1.so (main
  library)
- Explicitly add USE_XFCE components to the ports actually needing
  them.
- Cleanup dependencies, adding/removing missing/extra dependencies
- Change the referenced library in some LIB_DEPENDS to the actually
  linked one (avoids false positives in poudriere Q/A tests)
- Bump PORTREVISION on all touched ports, even indirectly due to
  the effect of removing forced dependencies on certain components
- Remove USES=fuse from gigolo. I could not find any kind f reference
  to fuse in the code.
- xfce4-bsdcpufreq-plugin: Also remove empty comment at the top of
  the Makefile

Welcome XFCE 4.16 to the FreeBSD ports tree!

Upstream announce: https://xfce.org/about/news/?post=1608595200

This XFCE release dropped support for GTK2 plugins and also dropped
GTK2 from all components.

WARNING: please check UPDATING before upgrading your packages. In
case of problems also read the libexo pkg-message.

Due to this some panel plugins and libraries will be removed since
they cannot compile anymore:

- print/xfce4-print
- x11/xfce4-quicklauncher-plugin

Update to 0.3.1.

Details:
- No functional changes.
- Includes build fix for upcoming xfce 4.16.

sysutils: Add missing USES={gnome,mate,php}

Update to version 0.3; uses gtk3 now

sysutils/xfce4-bsdcpufreq-plugin: fix build on GCC architectures

Use C11 compiler:
In file included from /usr/local/include/xfce4/libxfce4util/libxfce4util.h:33,
                 from panel-plugin/bsdcpufreq.c:27:
/usr/local/include/xfce4/libxfce4util/xfce-kiosk.h:37: error: redefinition of
typedef 'XfceKiosk'
/usr/local/include/xfce4/libxfce4util/xfce-kiosk.h:35: error: previous
declaration of 'XfceKiosk' was here

Welcome XFCE 4.14 to the FreeBSD ports tree

- This XFCE release uses almost exclusively gtk3, so the USES=xfce
  now defaults to gtk3
- Make x11-themes/gtk-xfce-engine an optional dependency(disabled
  by default), it only supports gtk2, so would leave miost of this
  XFCE version unthemed.
- Add Greybird as an optional and enabled dependency as a modern
  theme supporting both GTK versions and all other XFCE parts
- The xfce4-vala port is deprecated and removed. The VALA bindings
  are available in the library ports using the GIR and VAPI options
  (on by default)
- Fixed various missing library and portlint warnings (portmgr fixit
  blanket)
- Default Display Manager changed to lightdm (Thanks to woodsb02

Update ports in the remaining categories to not use GH_COMMIT.

With minor cleanups to make things simpler.

This does not really support GHC

Update USE_GITHUB so it does not require GH_COMMIT.

Using this new scheme allows only setting the _tag_ or _commit hash_ in
GH_TAGNAME and not having to know the hash for a tag.  This scheme will
download a tarball that has a different checksum than before due to a changed
directory name for extraction.

The following MASTER_SITES are provided to retain the old checksum and
directory structure (that require GH_COMMIT):
  GH -> GHL
  GITHUB -> GITHUB_LEGACY
