Each device is represented by a QDict. The returned QObject is a QList
of all devices.
This commit slightly changes the monitor output when 'info network' is used.

+/**
+ * do_network_info(): Network information
+ *
+ * Each network device information is stored in a QDict and the
+ * returned QObject is a QList of all devices.
+ *
+ * The QDict contains the following:
+ *
+ * - "name": device name
+ * - "vlan": only present if the device is attached to a VLAN, it is the id
+ * of the VLAN
+ * - "info": it is a QDict containing any of the following:
+ * - "model": type of the device
+ * - "macaddr": MAC address
+ * - "script": path to script used to configure the device
+ * - "downscript": path to script used to deconfigure the device
+ * - "fd": handle to the device
+ * - "ifname": name of the host device connected to the guest device
+ * - "mcast": multicast address
+ * - "cloned": true if the device is multicast clone
+ * - "connection_from": IP/port pair of an incomming connection
+ * - "connect_to": IP/port pair of an outgoing connection
+ *
+ * Example:
+ *
+ * [ { "name": "tap.0", "vlan": 0,
+ "info": { "script": "/etc/kvm/kvm-ifup", "downscript":
"/etc/qemu-ifdown",
+ "ifname": "tap0" } },
