qapi: Add "backing" to BlockStats

Currently there is no way to query BlockStats of the backing chain. This
adds "backing" field into BlockStats to make it possible.

The comment of "parent" is reworded.

qcow2: fix wrong value of L1E_OFFSET_MASK, L2E_OFFSET_MASK and REFT_OFFSET_MASK

Accoring to qcow spec, the offset fields in l1e, l2e and ref table entry
start at bit 9. The offset is cluster offset, and the smallest possible
cluster size is 512 bytes.

sheepdog: fix 'qemu-img map'

It was muted in the previous commit 4bc74be9. Let's revive it since nothing
prevents us to do it.

With this patch, following command will work as other formats:

$ qemu-img map sheepdog:image

drive mirror:fix memory leak

In the function mirror_iteration() > qemu_iovec_init(),
it allocates memory for op>qiov.iov, when the write request calls back,
but in the function mirror_iteration_done(), it only frees the op,
not free the op->qiov.iov, so this causes memory leak....

blkverify: Don't require protocol filename

If the filename is not prefixed by "blkverify:" in
blkverify_parse_filename(), the blkverify driver was not selected
through that protocol prefix, but by an explicit command line (or QMP)
option (like driver=blkverify)....
