In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

- Vte, add gtk3 support, enable introspection, update to 0.35.90
- Spice-gtk, add gtk3 support
- gtk-vnc, add gtk3 support
- Add libvirt-glib (thanks @bjornfor)
- Add usbredir
- qemu, enable usbredir
- spice-gtk, enable usbredir
- virt-manager, update to 1.0.1
[Bjørn:
* Set namePrefix = "" to preserve package name "virt-manager"
(instead of "python2.7-virt-manager")
* Add dconf to GIO_EXTRA_MODULES to get persistent settings in
virt-manager. Without it:
GLib-GIO-Message: Using the 'memory' GSettings backend. Your settings will not be saved or shared with other applications.
* Add ${gtk3}/share to XDG_DATA_DIRS to unbreak "Take Screenshot"
feature (fixes "Settings schema 'org.gtk.Settings.FileChooser' is not installed")
* gtk-vnc: don't pull "pkgs" attrset for optionalString, use stdenv.lib.optionalString instead.
