qed: refuse unaligned zero writes with a backing file

Zero writes have cluster granularity in QED. Therefore they can only be
used to zero entire clusters.

If the zero write request leaves sectors untouched, zeroing the entire
cluster would obscure the backing file. Instead return -ENOTSUP, which...

stream: complete early if end of backing file is reached

It is possible to create an image that is larger than its backing file.
Reading beyond the end of the backing file produces zeroes if no writes
have been made to those sectors in the image file.

This patch finishes streaming early when the end of the backing file is...

iscsi: Set number of blocks to 0 for blank CDROM devices

The number of blocks of the device is used to compute the device size
in bdrv_getlength()/iscsi_getlength().
For MMC devices, the ReturnedLogicalBlockAddress in the READCAPACITY10
has a special meaning when it is 0....

iscsi: move iscsi_schedule_bh and iscsi_readv_writev_bh_cb

Put these functions at the beginning, to avoid forward references
in the next patches.

iscsi: simplify iscsi_schedule_bh

It is always used with the same callback, remove the argument. And
its return value is never used, assume allocation succeeds.

iscsi: fix races between task completion and abort

This patch fixes two main issues with block/iscsi.c:

1) iscsi_task_mgmt_abort_task_async calls iscsi_scsi_task_cancel which
was also directly called in iscsi_aio_cancel

2) a race between task completion and task abortion could happen cause...
