Currently, there is no rate limit for qemu-img commit. This may
cause the task of qemu-img commit to consume all the bandwidth
of the storage. This will affect the IO performance of other processes
and virtual machines under shared storage. So we add support for
offline rate limit i

The type of input variable is unsigned int
while the printer type is int. So fix incorrect print type.

The function fcntl maybe return -1, which is not a unsigned type.
Unsigned type or Negative values should not do bitwise operator with
O_ACCMODE.

Concurrent IO becomes serial IO because of the qemu Coroutine lock,
which reduce IO performance severely.
So unlock Coroutine lock before bdrv_co_pwritev and
bdrv_co_preadv to fix it.

In blk_remove_bs, all I/O should be completed before removing throttle
timers. If there has inflight I/O, removing throttle timers here will
cause the inflight I/O never return.
This patch add bdrv_drained_begin before throttle_timers_detach_aio_context
to let all I/O completed befo
Avoid empty pointer access if the bs is NULL.
