Parallels driver indeed support Parallels Dirty Bitmap Feature in
read-only mode. The patch adds bdrv_supports_persistent_dirty_bitmap()

This will allow to copy CBT from Parallels image with qemu-img.
Note: read-write support is signalled through
bdrv_co_can_store_new_dirty_bitmap() and is different.
