Windows: Fix mythread_once() macro with Vista threads.
Don't call InitOnceComplete() if initialization was already done. So far mythread_once() has been needed only when building with --enable-small. windows/build.bash does this together with --disable-threads so the Vista-specific mythread_once() is never needed by those builds. VS project files or CMake-builds don't support HAVE_SMALL builds at all.
