SizedQueue#close(exception=false).
[Feature #10600]
Trying to deq from a closed empty queue return nil
if exception parameter equals to false (default).
If exception parameter is truthy, it raises
ClosedQueueError (< StopIteration).
ClosedQueueError inherits StopIteration so that you can write:
loop{ e = q.deq; (using e) }
Trying to close a closed queue raises ClosedQueueError.
Blocking threads to wait deq for Queue and SizedQueue will be
restarted immediately by returning nil (exception=false) or
raising a ClosedQueueError (exception=true).
Blocking threads to wait enq for SizedQueue will be
restarted by raising a ClosedQueueError immediately.
The above specification is not proposed specification, so that
we need to continue discussion to conclude specification this
method.
* test/thread/test_queue.rb: add tests originally written by
John Anderson and modify detailed behavior.

and ConditionalVariables to thread_tools.c. In other wowrds,
such classes are built-in.
[Feature #8919]
At first, I planned to embed only a Queue class.
However, rubygems requires 'thread.rb' (rubygems are
required at first, when launch MRI without --disable-gems).
So most of people require 'thread.rb' as an embedded library.
Now, ext/thread/thread.c is empty, only for a dummy for
compatibility.
* thread.c: move a definition of Mutex class to thread_tools.c.
And define Mutex class under Thread (so now Mutex is Thread::Mutex).
Because other thread related classes are also defined under Thread.
We remain ::Mutex as Thread::Mutex. Only an inspect result is changed.
* common.mk: add dependency from thread.o to thraed_tools.c.
