[virt-tools-list] [PATCH 06/11] virt-viewer-display: Use a borrowed reference to session

Before this patch there was a cyclic reference between VirtViewerSesion and
VirtViewerDisplay, since all VirtViewerDisplays are created / destroyed by
VirtViewerSession it is safe to assume that lifetime of VirtViewerSession >=
VirtViewerDisplay, so VirtViewerDisplay can take a borrowed reference
breaking the circle, and allowing proper cleanup on exit.

Note that there is no g_object_unref removed from virt-viewer-display, this
because there is no finalize / dispose and before this patch
VirtViewerDisplay never unref-ed the reference it hold to the session.
