  Modified files:
    sys/sys              conf.h 
    sys/kern             kern_conf.c 
  Log:
  Introduce dev_re[lf]thread() functions.
  
  dev_refthread() will return the cdevsw pointer or NULL.  If the
  return value is non-NULL a threadcount is held which much be released
  with dev_relthread().  If the returned cdevsw is NULL no threadcount
  is held on the device.
