xfce4 & xfce4-extras: move gnome-themes-standard back to xfce4

gnome-themes-standard had been moved to extras to try and help 32-bit
ARM builds generate a complete base DE, because of librsvg breakage.
With Xfce 4.16 having various components that now use CSDs, we really
must have this package as part of the basic install. (And, in any case,
32-bit ARM builds have different dependent package breakages now.)

meta-pkgs/xfce4: update to 4.16

Project summary of changes:

Today, after 1 year and 4 months of work, we are happy to announce the release \ 
of the Xfce desktop 4.16, a new stable version that supersedes Xfce 4.14.

4.16 was a special cycle in many respects (not only pandemic-wise, but also). \ 
One of the corner-stones of the non-code changes concerns our migration to \ 
GitLab, which is a change in development workflow and a huge step forward in \ 
terms of becoming more contributor-friendly and welcoming. In parts, the \ 
humungous changelog of Xfce 4.16 can be attributed to new contributors proposing \ 
merge requests (288 merge requests were merged or closed against our core \ 
components alone!). We also created a reference Docker container \ 
(xfce/xfce-build) and added CI pipelines to all components to ensure we don´t \ 
break the build. None of this would have been possible without our hosting being \ 
sponsored by Gandi and Fosshost!

Another big change concerns our visual identity, which we updated from a strange \ 
mix of random (partly Tango-based) icons and not following any naming scheme to \ 
a new, visually consistent set (following the freedesktop.org naming \ 
specification and a fixed color palette). We´re aware this will generate some \ 
work for icon theme maintainers (if they really want to override our gorgeous \ 
icons ;)) but we believe the longterm benefit outweighs this one-time effort.

And then finally we did some housekeeping (e.g. by dropping Gtk2 support code) \ 
and we also added features and improvements - all while sticking to a reasonable \ 
release cycle timeframe.

So without further ado, here go the main highlights of this release:

    The window manager received lots of updates and improvements again in the \ 
area of compositing and GLX. If a primary display was set, the alt-tab dialog \ 
will now only be shown there. Furthermore some handy new options to zoom the \ 
cursor along with rest of the display as well as an option to keep minimized \ 
windows in the most recently used list complement this release.
    We added a new plugin to the panel dubbed "statustray" which \ 
combines both StatusNotifier and legacy Systray items. An animated autohide \ 
transition now clearly shows the user "where the panel has gone" and a \ 
dark mode (enabled by default) makes the panel drop into the background a bit \ 
more with bright themes like the Gtk default Adwaita. Quite a few more smaller \ 
improvements were also introduced like accessing desktop actions from a \ 
Launcher´s right-click menu, the Window Buttons plugin now offering to `Launch \ 
a new instance` of an application and the Workspace Switcher now optionally \ 
showing automatic numbering for workspaces.
    Support for fractional scaling was added to the display dialog, along with \ 
highlighting the preferred mode of a display with an asterisk and adding aspect \ 
ratios next to resolutions. Falling back to a working mode after misconfiguring \ 
the display layout has also been made more robust.
    A new tab in the "About Xfce" dialog shows basic system \ 
information like CPU or GPU type. Furthermore the layout and visuals of the \ 
dialog were improved.
    The settings manager has improved search and filter capabilities. \ 
Furthermore all settings dialogs now use window decorations drawn by Gtk (client \ 
side decorations).
    The "Mime Settings" and "Preferred Applications" dialogs \ 
were merged into the "Default Applications" dialog - making it easier \ 
for users to set which application handles which filetype or action from one \ 
place.
    Our file manager Thunar received a boatload of fixes and quite a few notable \ 
features, including pause for copy/move operations, support for queued file \ 
transfer, remembering view settings per directory and support for transparency \ 
in Gtk themes.
    Our thumbnailing service tumbler became more flexible by being able to \ 
exclude paths. Furthermore support for .epub (e-book format) was added.
    The session manager offers improved support for GPG agent 2.1 and the \ 
setting dialog was visually improved.
    The power manager received a lot of bugfixes and some smaller features - \ 
among them a cleanup of its settings dialog, an optional visual indicator for \ 
when `Presentation Mode` is enabled, more accurate battery status icons and \ 
automatically dismissing low-power notifications upon the connection of a \ 
charger.
    The desktop mostly received bugfixes and small improvements - and the new \ 
default wallpaper!
    Our menu library garcon received new APIs and now doesn´t launch \ 
applications as children of the process hosting the menu anymore. The previous \ 
behavior led to applications crashing along with e.g. the panel.
    The applicaton finder now allows for sorting applications by \ 
"frecency" - a combination of frequency and recency.
    Dependency updates: Drop Gtk2, add LibGTop, bump Gtk >= 3.22, GLib and \ 
GDBus >= 2.50

Rename sysutils/xfce4-xarchiver to archivers/xarchiver

xarchiver is no longer part of xfce (for years), and the package
name and location makes it difficult to find. match other package
managers.
