block: apply COR-filter to block-stream jobs
This patch completes the series with the COR-filter applied to
block-stream operations.
Adding the filter makes it possible in future implement discarding
copied regions in backing files during the block-stream job, to reduce
the disk overuse (we need control on permissions).
Also, the filter now is smart enough to do copy-on-read with specified
base, so we have benefit on guest reads even when doing block-stream of
the part of the backing chain.
Several iotests are slightly modified due to filter insertion.
