History
gibbs cafb54d853 Implement SCB paging. This allows up to 255 active commands on 
aic7770 >= Rev E, aic7850, aic7860, aic7870, and ai7880 based controllers.

Make findSCB safer for non-tagged commands when tagged commands are
active on the controller.  The symptoms of this problem were
"Overlapped commands attempted" messages during error recovery
attempts.

Compact scratch ram usage.  This leaves 8 bytes free for future use.

Clean up some comments.
