Copy operation is defined by source and destination LBAs and LBA count to copy. For destiantion LBA and LBA count we reuse exiting fields `offset_blocks` and `num_blocks` in `struct spdk_bdev_io`. For source LBA new field `src_offset_blocks` was added. `spdk_bdev_get_max_copy()` function can be used to retrieve maximum possible unsplit copy size. Zero values means unlimited. It is allowed to submit larger copy size but it will be split into several bdev IOs.
