  Modified files:
    sys/dev/amr          amr.c amr_disk.c amrvar.h 
  Log:
  Change the queueing model used by the controller to drastically reduce
  the time spent at splbio().  We now avoid it unless we are actually
  manipulating the command queues themselves.  This doesn't improve
  performance noticeably, but should improve concurrency somewhat.

                         mlxvar.h 
  Log:
  Move some hardware-related items to the hardware-related header.
  
  Shift to using the same queueing strategy that the amr driver uses.
  Some simple tests indicate that we use about 2% of the CPU at around
  500tps with the controller completely saturated with I/O.
