[virt-tools-list] [virt-viewer] Fix --without-spice-gtk --with-ovirt build

[Christophe Fergeau]

The oVirt foreign menu support reused some existing bits from the older
SPICE controller foreign menu code. However, this controller code is
only built when spice-gtk support is built, while the oVirt foreign menu
code could be used with VNC as well. Trying to build the ovirt foreign
menu code without spice-gtk causes build issues due to missing
functions, or missing declarations, ...

The libgovirt/spice-gtk code which is entangled is the code to update
the foreign menu when its content changes, or when a new window is
opened. Making the oVirt-specific code independant from the
spice-gtk-specific code is not too complicated, but this comes at the
expense of a bit of code duplication, but this is only simple code
iterating over the GHashTable storing the opened windows.
