Fix #4533 - unregister callbacks on exception, fixing a memory leak

Our problem here was that if a thread blocked in threadWait or
threadDelay and was killed by an exception thrown from another thread,
its registration with the IO manager would not be cleared.

The fix is simply to install exception handlers that do the cleanup and
propagate the exception.

Fix #4514 - IO manager deadlock

* The public APIs for threadWaitRead and threadWaitWrite remain unchanged,
  and now throw an IOError if a file descriptor is closed behind their
  backs.  This behaviour is documented.

* The GHC.Conc API is extended to add a closeFd function, the behaviour
  of which is documented.

* Behind the scenes, we add a new evtClose event, which is used only when
  one thread closes a file descriptor that other threads are blocking on.

* Both base's IO code and network use the new closeFd function.
