block: add drive_backup HMP command
Make "drive_backup" available on the HMP monitor:
drive_backup [-n] [-f] device target [format]
The -n flag requests QEMU to reuse the image found in new-image-file,
instead of recreating it from scratch.
The -f flag requests QEMU to copy the whole disk, so that the result
does not need a backing file. Note that this flag *must* currently be
passed since the other sync modes ('none' and 'top') have not been
implemented yet. Requiring it ensures that "drive_backup" behaves like
"drive_mirror".
