Modified Files:
        src/sys/dev/scsipi: sd_scsi.c

Log Message:
sd_scsibus_get_parms():
* Use the "block descriptor length" to find the beginning of the mode page
  data.  This is critical, since some devices do not return a block descriptor
  at all.  (XXX There is disgusting structure hackery here.)
* Always use scsipi_size() (i.e. READ CAPACITY) to get the total disk size.
* Get the rotational rate from the rigid geometry page.
* Don't read the block size from the block descriptor if there was none.
* Get the block size from the flexible geometry page if possible.
* If we don't like the way page 4 smells, try page 5, rather than just punting.
