ChangeLog, gen_uuid.c:
  gen_uuid.c (get_random_bytes): Use O_NONBLOCK when trying to open
  	/dev/random.  Break out the /dev/random initialization code into a
  	get_random_fd() function, and use that function in uuid_generate() to
  	determine whether to use uuid_generate_random() or
  	uuid_generate_time().
