add missing std:: namespace qualifiers. remove unistd.h include which is only necessary for usleep but not available on all platforms. implement usleep with c++ std libraries <thread> and <chrono>.

Using <pthread.h> is sometimes also problematic to build on certain platforms and can be replaced by std::thread and std::mutex. |
pthread_mutex_trylock returns zero on success. std::mutex::try_lock returns true on success. The conditions checked for success of pthread_mutex_trylock, so they should now require result value of `true`.
