d9bafc3fba rewrite scoped_timer for linux 
The previous version was racy and could lead to crashes.
The timer could be deleted before the callback was called, making it execute on already freed memory

This new version is similar to Mac's. It spawns its own thread and uses pthread_cond_wait.
Care is taken for small timeouts to avoid races in the thread creation and timer destruction.
