  Log:
  After some complaints about the dir names, the random device is
  now in dirs called sys/*/random/ instead of sys/*/randomdev/*.
  
  Introduce blocking, but only at startup; the random device will
  block until the first reseed happens to prevent clients from
  using untrustworthy output.
  
  Provide a read_random() call for the rest of the kernel so that
  the entropy device does not need to be present. This means that
  things like IPX no longer need to have "device random" hardcoded
  into thir kernel config. The downside is that read_random() will
  provide very poor output until the entropy device is loaded and
  reseeded. It is recommended that developers do NOT use the
  read_random() call; instead, they should use arc4random() which
  internally uses read_random().
  
  Clean up the mutex and locking code a bit; this makes it possible
  to unload the module again.
