block: BLOCK_IO_ERROR QMP event
This commit introduces the bdrv_mon_event() function, which
should be called by block subsystems (eg. IDE) when a I/O
error occurs, so that an QMP event is emitted.
The following information is currently provided in the event:
- device name
- operation (ie. "read" or "write")
- action taken (eg. "stop")
Event example:
{ "event": "BLOCK_IO_ERROR",
"data": { "device": "ide0-hd1",
"operation": "write",
"action": "stop" },
"timestamp": { "seconds": 1265044230, "microseconds": 450486 } }
