Add USES=compiler:c11 to fix:
../libxfce4util/xfce-kiosk.h:37: error: redefinition of typedef 'XfceKiosk'
../libxfce4util/xfce-kiosk.h:35: error: previous declaration of 'XfceKiosk' was here

Approved by:	mentors (implicit approval)

- 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
  for help)
- Add x11/xfce4-screensaver as an optional dependency to the
  xfce4-goodies (enabled by default)
- Remove dependency on x11-fm/thunar-vfs and deprecate the port.
  It is EOL upstream and the functionality is included in thunar
  itself

Add an XFCE SITE_SUBDIR abbreviation and use it forf or the xfce ports,
which removes the need to set MASTER_SITE_SUBDIR in any of them.

This fixes ports that have USES=xfce but do not use the XFCE MASTER_SITE,
namely sysutils/xfce4-bsdcpufreq-plugin.
