net: stream: add QAPI events to report connection state
The netdev reports NETDEV_STREAM_CONNECTED event when the backend
is connected, and NETDEV_STREAM_DISCONNECTED when it is disconnected.
The NETDEV_STREAM_CONNECTED event includes the destination address.
This allows a system manager like libvirt to detect when the server
fails.
For instance with passt:
{ 'execute': 'qmp_capabilities' }
{ "return": { } }
{ "timestamp": { "seconds": 1666341395, "microseconds": 505347 },
"event": "NETDEV_STREAM_CONNECTED",
"data": { "netdev-id": "netdev0",
"addr": { "path": "/tmp/passt_1.socket", "type": "unix" } } }
[killing passt here]
{ "timestamp": { "seconds": 1666341430, "microseconds": 968694 },
"event": "NETDEV_STREAM_DISCONNECTED",
"data": { "netdev-id": "netdev0" } }
