      implement qemu_blockalign (Stefano Stabellini) · e268ca52

      this patch adds a buffer_alignment field to BlockDriverState and
      implements a qemu_blockalign function that uses that field to allocate a
      memory aligned buffer to be used by the block driver.
      buffer_alignment is initialized to 512 but each block driver can set
      a different value (at the moment none of them do).
      This patch modifies ide.c, block-qcow.c, block-qcow2.c and block.c to
      use qemu_blockalign instead of qemu_memalign.
      There is only one place left that still uses qemu_memalign to allocate
      buffers used by block drivers that is posix-aio-compat:handle_aiocb_rw
      because it is not possible to get the BlockDriverState from that
      function. However I think it is not important because posix-aio-compat
      already deals with driver specific code so it is supposed to know its
      own needs.
