Setting the zoom-level using the command line option '--zoom' is not
working for vnc guests. This problem can be solved by emitting
the "display-desktop-resize" signal when vnc is initialized.

Set the display's session property in the constructor. If the session is
not set, then virt_viewer_display_get_session() doesn't return anything
useful.

We were setting the show_hint to READY as soon as we got the vnc-connected
signal. But there may be an authentication step between vnc-connected and
vnc-initialized. In this case, we switch to an empty black display during the
authentication step instead of showing the 'waiting for display N' status.

When clicking the close button on a virt-viewer window with
a VNC session open, while the VNC session terminates, the
window does not go away.
The problem is that the virt_viewer_session_vnc_disconnected
method never gets invoked. The close button triggers a call
to virt_viewer_session_clear_displays which unrefs the
VirtViewerDisplayVnc instance. This in turn triggers a call
to gtk_container_destroy, which destroys all widgets it
contains, ie the VncDisplay * object.
With the VncDisplay object in its dispose phase, no signals
will ever be emitted, thus the 'vnc-disconnected' signal
never gets seen.
The design issue is that VirtViewerDisplayVnc is assuming
it owns the VncDisplay, whereas in fact the real owner is
the VirtViewerSessionVnc object.
The solution is to introduce a new virt_viewer_display_close
method which can be used to de-parent the widget before
VirtViewerDisplay is unref'd.
The VirtViewerSessionVnc object also needs to hold a full ref
on the VncDisplay object, not merely a floating reference
* virt-viewer-display-spice.c, virt-viewer-display.c,
virt-viewer-display.h: Add virt_viewer_display_close
* virt-viewer-display-vnc.c: Deparent VNC widget in
virt_viewer_display_close impl
* virt-viewer-session-vnc.c: Improve logging
* virt-viewer-session.c: Call virt_viewer_display_close
before unrefing display
* virt-viewer-window.c: Improve logging

To facilitate introduction of multi-head support, pull some of
the VirtViewerDisplay class out into a new VirtViewerSession
class.

Add many signals to VirtViewerDisplay which are emitted when various
events occur. This lets us remove all the code in the VirtViewerDisplay
subclasses which call back into VirtViewer methods. Instead VirtViewer
can simply connect signals to the display

Turn VirtViewerDisplay into a Gtk widget instead of just a GObject,
by merging the functionality from VirtViewerAlign
