Add debug function 'is_single_threaded'

Browse Source 
Usage:

AIThreadID foo(AIThreadID::none);

...

  llassert(is_single_threaded(foo));
...
  llassert(is_single_threaded(foo));
...
etc

The first call to is_single_threaded(foo) remembers the thread,
and after that it is enforced that any call from anywhere that uses foo
is done by the same thread.

If AIThreadID::none is omitted then the thread is enforced to the thread
that creates the AIThreadID.
