Daniel P. Berrange 3c3237b951 Convert to use GTK3 and GObject Introspection bindings
Switch over to use GObject introspection bindings for all python
modules related to GObject/GTK3/etc. It is not possible to mix
and match old pyggtk/pygobject manual bindings with new introspection
based bindings so it must be all changed in one go.

Imports like

    import gtk

Change to

    from gi.repository import Gtk

The vmmGObject class is changed to always inherit from GObject.GObject
There is no compelling reason to avoid a GObject dep for the
virt-manager TUI & it horribly messed up the code.

Signal declarations are changed from

  vmmChooseCD.signal_new(vmmChooseCD, "cdrom-chosen", [object, str])

To

     __gsignals__ = {
        "cdrom-chosen": (GObject.SignalFlags.RUN_FIRST, None, [object, str])
    }

which is required by new GObject bindings

Most of the rest of the change is simply dealing with renamed
constants / classes.

Alot of legacy compat code was removed - ie helpers which
check to see if certain GTK2 methods are available are no
longer required since we're mandating GTK3 only.

The event loop is replaced with LibvirtGLib's event loop.

Still todo

 - Rip out all DBus stuff & make vmmEngine class inherit GtkApplication
   which provides unique support & DBus method handling
 - Switch to use LibvirtGConfig & LibvirtGObject for libvirt interaction
 - Possibly switch to Python 3 too ?
 - Figure out why GNOME keyring is missing Introspection support

My suggestion is that the standalone GIT repo for virt-install
only live on as a support branch for legacy platforms.

A stable-0.9 branch of virt-manager can be kept for legacy PyGtk2
based virt-manager releases.

The virt-manager master branch should exclusively use GObject
inspection and ideally Python3 and contain both the virt-manager
and virt-install codebases in one since they are intimately
related to each other & using separate GIT repos has needlessly
complicated life for everyone.
