* Clean-up EntityManager a bit - use tsl::robin_set instead of std::set (which should have been unordered::set anyways). - getListeners() now returns a vector which avoids to traverse a set twice. Turns out that copying the set wasn't as efficient as I thought. * Improve jobsystem a bit We recently added a job reference counting mechanism, but we were a bit too aggressive about taking/release references. Also make the API more complete by adding explicit retain/release, which is needed to allow several threads to wait on the same job. Also improve futex code by inlining it.
