Decouple the I/O accounting from bdrv_aio_readv/writev/flush and make the hardware models call directly into the accounting helpers. This means: - we do not count internal requests from image formats in addition to guest originating I/O - we do not double count I/O ops if the device model handles it chunk wise - we only account I/O once it actuall is done - can extent I/O accounting to synchronous or coroutine I/O easily - implement I/O latency tracking easily (see the next patch) I've conveted the existing device model callers to the new model, device models that are using synchronous I/O and weren't accounted before haven't been updated yet. Also scsi hasn't been converted to the end-to-end accounting as I want to defer that after the pending scsi layer overhaul.
