sysutils/xfce4-diskperf-plugin: Update to 2.7.0

INSTALLS_ICONS: retire the macro and rework the related dependencies

While here, make sure gtk-update-icon-cache is only on run dependency
where added as a dependency
Enforce gtk3 to depend on gtk-update-icon-cache (previously it was
inheriting the dependency)

Remove # $FreeBSD$ from Makefiles.

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 xfce4-diskperf-plugin to 2.6.3

Two new XFCE4 fixes for GCC architectures.

Approved by:	mentors (implicit approval)

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 to 2.6.2

By default libtool replaces -export-symbols <file> with -retain-symbols-file
<file> on ELF systems, but this doesn't really do what -export-symbols is
meant to do.  On GNU ELF systems it converts <file> to a simple version
script first and then uses -version-script instead of -retain-symbols-file.
Let USES=libtool patch libtool scripts to do this on all systems with GNU
ld(1).

Bump PORTREVISION on all ports where the build log contains -export-symbols.

audio/calf: This port builds a module that now exports only one function,
but it also builds a number of executables that link to this module and
expect to see other functions.  Because it's already a bit dodgy to link to
a module (libtool warns about this) let the module continue to export only
one function and instead build an ordinary library from the same source that
the executables can link to.  Fix a number of other issues in the same

USES=xfce: Stop overriding MASTER_SITE_SUBDIR.

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.
