raw_bsd: add offset and size options
Added two new options 'offset' and 'size'. This makes it possible to use
only part of the file as a device. This can be used e.g. to limit the
access only to single partition in a disk image or use a disk inside a
tar archive (like OVA).
When 'size' is specified we do our best to honour it.
