Shift bits for CAM flags so that the top bit isn't set in an enum

Browse Source 
(at request of Ken Merry). Garbage collect items out of the ccb_getdev
structure and and a length field so that consumes will know how much
of the inq_data tag is valid. Clean up a few misspellings. Add
a CAM_SEND_STATUS target mode flag.

All of this necessitated a CAM_VERSION bump.

JHK approved.
