implementations for windows and everyone else. They are now written to use PR_AtomicIncrement and PR_AtomicDecrement.

A side effect of this change is that no one needs to include "windows.h" in .cpp files which were implementing threadsafe
interfaces. You used to have to do this before with the old implementations.
