  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.
