details: Add auto USB redirection support in console viewer
Add "Redirect USB device" option in console viewer. Initialize and embed UsbDeviceWidget object from SpiceClientGtk into a dialog to let user choose available USB devices for redirection. Throw an error message if USB connection failed. Auto-redirection is enable by default. There is race between creating usbredir channel and calling has_usb_redirection() when initializing spice session like happening on virt-viwer. So adding a new signal handler on_details_menu_virtual_manager_activate() to recheck the status of usbredir channel, set "Redirect USB device" option sensitive if it is availiable.
