This patch series introduces a new QMP command "query-netdev" to get
information about currently attached backend network devices (netdevs).
Also, since the "info_str" field of "NetClientState" is now deprecated,
we no longer use it for netdevs, only for NIC/hubports.
The HMP command "info network" now also uses the new QMP command inside.

Usage example:

-> { "execute": "query-netdev" }
<- { "return": [
         {
             "listen": "127.0.0.1:90",
             "type": "socket",
             "peer-id": "hub0port1",
             "id": "__org.qemu.net1"
         },
         {
             "script": "/etc/qemu-ifup",
             "downscript": "/etc/qemu-ifdown",
             "ifname": "tap0",
             "type": "tap",
             "peer-id": "net5",
             "vnet_hdr": true,
             "id": "tap0"
         },
         {
             "ipv6": true,
             "ipv4": true,
             "host": "10.0.2.2",
             "ipv6-dns": "fec0::3",
             "ipv6-prefix": "fec0::",
             "net": "10.0.2.0/255.255.255.0",
             "ipv6-host": "fec0::2",
             "type": "user",
             "peer-id": "net0",
             "dns": "10.0.2.3",
             "hostfwd": [
                 {
                     "str": "tcp::20004-:22"
                 }
             ],
             "ipv6-prefixlen": 64,
             "id": "netdev0",
             "restrict": false
         }
     ]
   }

v4->v5:
- Enable qtest of query-netdevs for AVR and RX archs.
- Bump "Since" version in QAPI to 6.0.

v3->v4:
- Rename "query-netdevs" to "query-netdev".
- Copy netdev drivers to new QAPI enum "NetBackend".

v2->v3:
- Remove NIC and hubports from query-netdevs.
- Remove several fields from NetdevInfo since they are unnecessary.
- Rename field @peer to @peer-id.
- Add support of vhost-vdpa.
- Keep "info_str" for NIC/hubports, but remove it for netdevs.

v1->v2:
- Rewrite HMP "info network" to get information from results of QMP command.
- Remove obsolete field "info_str" from "NetClientState".
