General SCSI Device for 2090 / 2091 boards with source 

What's supported:
- - - - - - - - -
o  Autorecognition of direct access and sequential access devices. This
   enables normal CMD_READ and CMD_WRITE operation for direct access AND
   sequential access devices.

o  TD_PROTSTATUS works by really querying the unit, so it should work
   with removable media, that can be write protected.

o  Fully supported SCSIDirect commands. (The whole device is built around
   an scsi-direct executor)

o  SCSI units are mapped directly into device units (no offset 3 like
   the 2090 hddisk.device did)
