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 growth.

qcow2: Fix "total clusters" number in bdrv_check This should be based on the virtual disk size, not on the size of the image. Interesting observation: With some VM state stored in the image file, percentages higher than 100% are possible, even though snapshots themselves are ignored. This is a qcow2 bug to be fixed another day: The VM state should be discarded in the active L2 tables after completing the snapshot creation.

block/qcow2: Add qcow2_refcount_area() This function creates a collection of self-describing refcount structures (including a new refcount table) at the end of a qcow2 image file. Optionally, these structures can also describe a number of additional clusters beyond themselves; this will be important for preallocated truncation, which will place the data clusters and L2 tables there. For now, we can use this function to replace the part of alloc_refcount_block() that grows the refcount table (from which it is actually derived).

iotests: drop qemu_img_verbose() helper qemu_img_verbose() has a drawback of not going through generic qemu_img_pipe_and_status(). qemu_img_verbose() is not very popular, so update the only two users to qemu_img_log() and drop qemu_img_verbose() at all.
