* modules/access/vcd/*, modules/access/cdda.c: changed ioctl_ReadSector() into ioctl_ReadSectors(), a function that can read multiple sectors at a time.
  Modified the cdda plugin to read 20 sectors at a time. This was necessary because it was overkill to read the data sectors by sectors and was creating problems under Windows.
