qemu_graphic_console_is_multihead() declares the graphical console "c" a "multihead" console if there are two different graphical consoles in the system that (a) both reference "c->device", and (b) have different "c->head" numbers. In effect, if at least two graphical consoles exist that are different heads of the same device that underlies "c". In fact, "c" may be one of these two graphical consoles, or "c" may differ from both of those consoles (in case "c->device" has at least three heads). The loop currently uses this awkward "two different consoles" approach because the function used not to have access to "c", only to "c->device", which didn't allow for fetching (and comparing) "c->head". But, we've changed that in the last patch; we now pass all of "c" to qemu_graphic_console_is_multihead(). Thus, look for the *first* (and possibly *only*) graphical console, if any, that refers to the same "device" as "c", but by a different "head" number.
