mirror: add buf-size argument to drive-mirror

This makes sense when the next commit starts using the extra buffer space
to perform many I/O operations asynchronously.

mirror: perform COW if the cluster size is bigger than the granularity

When mirroring runs, the backing files for the target may not yet be
ready. However, this means that a copy-on-write operation on the target
would fill the missing sectors with zeros. Copy-on-write only happens...

qemu-iotests: Test concurrent cluster allocations

This adds some first tests for qcow2's dependency handling when two
parallel write requests access the same cluster.

qemu-iotests: qcow2: Test growing large refcount table

Actually writing all the content with 512 byte sector size would take
forever, therefore build the image file with a Python script and use
qemu-io for the last write that actually triggers the refcount table...

tests: allow qemu-iotests to be run against nbd backend

To do this, we start a qemu-nbd process at _make_test_img and kill
it in _cleanup_test_img. $TEST_IMG is changed to point at the TCP
server. We also remove the checks for existence of binaries from
common.config - they're duplicated in common, and we can make the...

The new options are tested with blkdebug on both the source and the
target.

qemu-iotests: Add 043 backing file chain infinite loop test

This new test verifies that qemu-img info --backing-chain safely aborts
when an image file has a backing file infinite loop.
