Mutex class

A mutex is a lockable object that's designed to signal when critical sections of code need exclusive access, preventing O ther threads with the same protection from executing concurrently and access the same memory locations.

mutexobjects provide exclusive ownership and do no support recursivity (i.e., a thread shall not lock a mutex it already owns) -See for a recursive_mutex alternative class that does.

It's guaranteed to be a standard-layout class.
