This feature can be used in case where users are avoiding the iops limit by doing jumbo I/Os hammering the storage backend. Signed-off-by: NBenoit Canet <benoit@irqsave.net> Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com>

The max parameter of the leaky bucket throttling algorithm can be used to allow the guest to do bursts. The max value is a pool of I/O that the guest can use without being throttled at all. Throttling is triggered once this pool is empty. Signed-off-by: NBenoit Canet <benoit@irqsave.net> Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com>

Now image info will be retrieved as an embbed json object inside BlockDeviceInfo, backing chain info and all related internal snapshot info can be got in the enhanced recursive structure of ImageInfo. New recursive member *backing-image is added to reflect the backing chain status. Signed-off-by: NWenchao Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com>

This patch adds function bdrv_query_image_info(), which will retrieve image info in qmp object format. The implementation is based on the code moved from qemu-img.c, but uses block layer function to get snapshot info.

This patch adds function bdrv_query_snapshot_info_list(), which will retrieve snapshot info of an image in qmp object format. The implementation is based on the code moved from qemu-img.c with modification to fit more for qmp based block layer API.

bdrv_snapshot_dump() and bdrv_image_info_dump() do not dump to a buffer now, some internal buffers are still used for format control, which have no chance to be truncated. As a result, these two functions have no more issue of truncation, and they can be used by both qemu and qemu-img with correct parameter specified.

This patch is a pure code move patch, except following modification: 1 get_human_readable_size() is changed to static function. 2 dump_human_image_info() is renamed to bdrv_image_info_dump(). 3 in qmp_query_block() and qmp_query_blockstats, use bdrv_next(bs) instead of direct traverse of global array 'bdrv_states'. 4 collect_snapshots() and collect_image_info() are renamed, unused parameter *fmt in collect_image_info() is removed. 5 code style fix. To avoid conflict and tip better, macro in header file is BLOCK_QAPI_H instead of QAPI_H. Now block.h and snapshot.h are at the same level in include path, block_int.h and qapi.h will both include them.
