   Log:
   Enhance the Linux emulation layer to make MegaRAID SAS managements tool happy.
   Add back in a scheme to emulate old type major/minor numbers via hooks into
   stat, linprocfs to return major/minors that Linux app's expect.  Currently
   only /dev/null is always registered.  Drivers can register via the Linux
   type shim similar to the ioctl shim but by using
   linux_device_register_handler/linux_device_unregister_handler functions.
   The structure is:
 
       struct linux_device_handler {
           char    *bsd_driver_name;
           char    *linux_driver_name;
           char    *bsd_device_name;
           char    *linux_device_name;
           int     linux_major;
           int     linux_minor;
           int     linux_char_device;
       }; 
 
   Linprocfs uses this to display the major number of the driver.  The
   soon to be available linsysfs will use it to fill in the driver name.
   Linux_stat uses it to translate the major/minor into Linux type values.
 
   Note major numbers are dynamically assigned via passing in a -1 for
   the major number so we don't need to keep track of them.
 
   This is somewhat needed due to us switching to our devfs.  MegaCli
   will not run until I add in the linsysfs and mfi Linux compat changes.
