console: allow pinning displaychangelisteners to consoles
DisplayChangeListener gets a new QemuConsole field, which can be set to non-NULL before registering. This will pin the QemuConsole, so that particular DisplayChangeListener will not follow console switches. spice+gtk (which don't support text console input anyway) are switched over to be pinned to console 0, which usually is the graphical display.
