Anatol Belski fd8495b342 block: qcow: Use aligned I/O in QcowSync
Store the alignment from the data file in QcowSync. Use AlignedBuf
directly in read_vectored and write_vectored as the intermediate
buffer so that aligned_pread/aligned_pwrite can skip the bounce
copy when offset and length are naturally aligned.

Use gather_from_iovecs_into to gather iovec data directly into the
aligned buffer.
