[libvirt] [PATCH 10/13] vsh: Introduce new global initializer

[Erik Skultety]

Right now, there's very little to do in global initializer besides
registering client hooks, but there's a potential to have some more
features that will need to be properly initialized beforehand (exporting
vshControl pointer only would definitely make use of this).
