Duplicate function in thread_pthread.h

[Inada Naoki]

Do you know C macros?
Two implementations is switched by USE_SEMAPHORES.

#ifdef USE_SEMAPHORES
...
void
PyThread_free_lock(PyThread_type_lock lock)
...
#else /* USE_SEMAPHORES */
...
void
PyThread_free_lock(PyThread_type_lock lock)
...
#endif /* USE_SEMAPHORES */
