* Use two cdevsw's for ugen(4): one for control endpoints, and one for
  data endpoints.  The control endpoint doesn't need read/write/poll
  operations, and more importantly, the thread counts should be
  separate so that the control endpoint can properly reference itself
  while deleting and recreating the data endpoints.
* Add some macros that handle referencing/releasing devices, and use them
  for sleeping/woken-up and open/close operations as apppropriate.
* Use d_purge for FreeBSD, and a loop testing the open status for all
  the endpoints for NetBSD and OpenBSD, so that when the device is
  detached, the right thing always happens.
