Make clear that the DATA COMPRESSION page is a SCSI-3 entity- not a SCSI-2

Browse Source 
entity. Add the Device Configuration page data structure- this structure
should be used if you fail to fetch the DATA COMPRESSION page. Make a union
type of a mode header, a device configuration page and the data compression
page.

Add a couple of QIC density defines (QIC 2G/QIC 4GB).
