- Removed platform-specific implementations. - Now all semaphores are in-object, unless they need to be conditionally created. - Similarly to `Mutex`, provided a dummy implementation for when `NO_THREADS` is defined. - Similarly to `Mutex`, methods are made `const` for easy use in such contexts. - Language bindings updated: `wait()` and `post()` are now `void`. - Language bindings updated: `try_wait()` added. Bonus: - Rewritten the `#ifdef` in `mutex.h` to meet the code style.
