gtk+3: Upgrade to 3.16.4

* Drop --disable-gtk2-dependency and the patch for
  gtk/native/Makefile.am: gtk-update-icon-cache is no longer used at
  build time and as a result the option was removed.
* Add dependency to libepoxy
* Add dependency to virtual/mesa for wayland-egl
* Package new binaries gtk3-icon-browser and gtk-encode-symbolic-svg
* Add a backported patch that allows server side window decorations
  in all cases
* RRECOMMEND adwaita-icon-theme-symbolic: GTK+ widgets expect a
  symbolic theme to be installed

+Subject: window: Check if we can use CSD before enabling them
+
+The change in 03213b9509fc1df16c66194ea168aed6c15110e9 changed the rules
+as to when CSD can be enabled, but it also unconditionally enables CSD
+with the implicit assumption that client-side shadows were the real
+issue, and that we could work around that by drawing our own borders.
+This also means that setting a titlebar for a GtkWindow will enable CSD
+unconditionally.
+
+In reality, some window managers (like Matchbox) *only* support
+server-side decorations, and will ignore all hints to the contrary, to
+the point of drawing decorations at random locations on top of the
+window.
+
+Since CSD are enabled unconditionally, the GTK_CSD environment variable
+is also not a suitable escape hatch.
+
+In the grand tradition of asking ourselves if we should do something
+just because we can, we should split the environment checks from the
+checks on what the user requested; by doing that, we can also check
+when enabling client-side decorations, and ideally bail out if needed.
