  Log:
  Major update to the 'twe' driver.
  
   - Layout reorganisation to enhance portability.  The driver now has
     a relatively MI 'core' and a FreeBSD-specific layer over the top.
     Since the NetBSD people have already done their own port, this is
     largely just to help me with the BSD/OS port.
  
   - Request ID allocation changed to improve performance (I'd been
     considering switching to this approach after having failed to come
     up with a better way to dynamically allocate request IDs, and seeing
     Andy Doran use it in the NetBSD port of the driver convinced me
     that I was wasting my time doing it any other way).  Now we just
     allocate all the requests up front.
  
   - Maximum request count bumped back to 255 after characterisation
     of a firmware issue (off-by-one causing it to crash with 256
     outstanding commands).
  
   - Control interface implemented.  This allows 3ware's '3dm' utility to
     talk to the controller.  3dm will be available from 3ware shortly.
  
   - Controller soft-reset feature added; if the controller signals a
     firmware or protocol error, the controller will be reset and all
     outstanding commands will be retried.
